All alcohol products are a certain composition based on ethyl alcohol, aromatic additives and coloring elements. Unlike high-quality products, in Surrogate, the main substance is methanol, which has a strong poisoning effect on the body. The ability to correctly determine, methyl or ethyl alcohol is in the composition of alcohol products, will help save not only health, but also life.
Ethyl alcohol or ethanol underlies each alcoholic beverage ranging from beer and ending with exotic drinks.
One of the most terrible alcohol poisoning is the use of methyl (technical) alcohol instead of ethyl (food) or medical
Scientific name of alcohol containing ethyl - ethanol. His chemical formula C2H5OH. This substance is recognized as psychoactive and used as an antidepressant. The main spread of ethanol in the following industries:
The main difference between ethyl alcohol from methyl is that only organic products are used for its production. Ethanol is formed as a result of their fermentation, for which special yeast apply. The resulting solution passes several stages of additional processing and distillation. After passing all the filtering stages in the resulting solution, the ethanol content does not exceed twenty percent.
The main active component of methyl alcohol - Methanol. This composition has the chemical formula CH3OHAnd in its essence is a real poison. His getting into the body can lead to strong poisoning, as a result of which various pathologies develop, sometimes the use of methanol leads to a fatal outcome.
This monoatomic alcohol is obtained due to the processing of wood formic acid and special substances. The composition is used as a chemical solvent. Very often, this solution underlies formaldehyde. The main difference in the action on the body of these compositions is that ethyl is much easier to absorb the body. In case of methyl in the esophagus, the oxidation processes begin, which leads to the formation of harmful toxins.
The first organs that are subjected to the destructive effects of methyl is the eyes and the nervous system. The blindness is one of the main symptoms of the use of poor-quality alcohol-containing drink.
The problem is that in taste, odor and color technical alcohol is no different from the food
The use of poor-quality alcohol products does not lead to such destructive consequences as the use of methyl alcohol. What is the difference between ethyl alcohol from methyl at first glance quite difficult. Both of these composition are identical to taste and color of the fluid.
Methanol is one of the most strongest poisons known to date. Its use inhibits the nervous system and adversely affects the vessels. When complications caused by methyl use are expressed in visual organs - this leads to the fact that a person completely loses his eyesight. Wrap this process reversed is very difficult. The use of methyl alcohol can provoke the following reactions:
The use of surrogate can cause a short-term loss of memory, attacks of dizziness and loss of consciousness. When the amount of drunk exceeds one hundred grams, a fatal outcome is possible.
One way to check the ethyl alcohol or methyl alcohol is set fire to the drink. Ethyl alcohol burns with a flat flame, which has a blue tint. Unlike him, Methyl flame color is green.
Typically, methanol is contained in solvents, non-freezing fluids and other means of household chemicals that are not intended to use insufficient
It is possible to determine methanol in alcohol using ordinary potatoes. To do this, a small piece of peeled root is added to a glass with a liquid. Unfortunately, the oxidation process takes a certain period of time. However, as a result of this test, potatoes can change its color. When potatoes change its color on a gentle pink - this is a one hundred percent sign of methyl liquid.
Another chemical test solution can be made at home. It requires a copper wire. It is heated to the state of redness on fire, and then immediately dip in the container with liquid. As a result of chemical processes, a sharp, unpleasant smell may appear. Its presence suggests that methanol is located in the mixture. Ethyl behaves with these tests is completely different. The mixture begins to emit thin apple fragrance.
This reaction can be achieved by another method. To do this, a small piece of wool is needed, which is thoroughly soaked in solution, after the wata absorbs the solution to be aligned. As a result of the combustion process, the same specific smell is formed, with which it is possible to determine the type of alcohol contained in the product.
Methyl alcohol is a highly toxic substance that refers to a group of alcohols having a one-nose structure. To begin pathological changes in the body, it is enough to use ten millilitres of such a substance. As a result of such an impact on the body, the question of analyzing alcoholic beverages on the methanol content is becoming important for life. How to distinguish alcohol methyl from ethyl will answer any person who has the necessary knowledge in the field of chemistry, but what to do a person when there is no whole necessary laboratory equipment at hand.
Buy alcohol in the stores causing trust, there is a risk of becoming a victim of fakes much lower than in dubious points of sale
One of the most dangerous methyl alcohol factors is that it is completely identical to the external signs of the composition contained in ethyl. Their main difference is the principle of action on the body. As a result of the action of methanol, acute poisoning of toxic substances occurs.
To distinguish one alcohol from the other is quite easy to use any of the methods described above. But how to distinguish methyl alcohol from ethyl, if in the product they are contained in equal amounts or with a certain ratio. It is worth noting right away that the use of such a product is extremely undesirable, and its samples can be carried out only in laboratory conditions. Conducting such studies is a priority for confirming or refuting the methanol content in ethyl alcohol.
To determine the amount and quality of alcohol contained in alcohol in laboratory conditions, special "iodoform" samples are used.
In addition, the technique is used, with which methyl is converted into such substances as formaldehyde. For such experience, it is necessary to have a special test tube, the top of which contains a pipe for gas removal. Sulfuric acid is poured into such a test tube with the addition of potassium permanganate. These two substances, enhancing the reaction, formaldehyde. Various effects on this substance lead to a variety of reactions, which in most cases confirms the presence of methanol. At the domestic conditions there is a single method using copper wire.
Of course, checking the composition produced at home will not make one hundred percent result. Recently, a mixture is common, where medical alcohol is used to mask methyl. Such a composition may not show a certain reaction to all manipulations.
A full result can be obtained only having conditions for laboratory checking. If there is at least the slightest hint that the purchased products may be poor quality, it is recommended to get rid of it immediately.
Distinguish ethanol from technical alcohol at home can be in several ways. At the same time, special equipment, devices, devices (except, thermometer) are required.
Heating samples
After heating alcohol in a metal container on the fire of the home plate, it is necessary to measure the booster temperature of the liquid. Ethyl alcohol is higher - (78C), at the technical counterpart below (64c).
Testing copper wire
Now it is not a test sample, but copper wire. To increase the contact area, it is better to roll into a spiral.
Heating is needed to white or black, so that copper oxide began to stand out.
The hotbed is lowered into the liquid, the character of which is determined by the smell: methanol has an unpleasant smell, ethyl alcohol smells like an apple (we are too thin, but distinguishable).
Chemical reaction method to manganese
For this test, a transparent container is needed into which alcohol is placed. A few drops of mangartage (either crystallines) will cause acetic smell without bubbles in drinking alcohol. In methanol, the reaction will begin with the release of gases (bubbles).
Iodine reaction
It will take a heated to 50c water, alkali (sodium hydroxide), a drop of iodine, alcohol. When mixing all components in drinking alcohol, iodoform (yellow precipitate) should appear. In technical alcohol, such a reaction is impossible - the sediment will not.
Long-term way
In the methyl alcohol, raw purified potatoes in a few hours pose, and the color does not change in the drinking.
All these methods can be used, only for clean products. They are not suitable for their mixture. A person risks to go blind from the use of methanol.

Alcohol is the main ingredient of almost all alcoholic beverages. But in order to get as a result, high-quality, delicious, and most importantly safe products, it is necessary to choose the right alcohol.
Alcohol can be two types: ethyl and methyl. Which one you can drink or eat in food, and what color they burn, we will tell below.
Ethyl alcohol is two types: Food and medical. It is suitable for eating, however, it must be diluted with water before it, otherwise, due to the high alcohol concentration, you can get serious burns of the digestive tract and the oral cavity.
Without special manipulations, "on the eye" to distinguish methyl alcohol from ethyl is impossible. Both fluids are transparent, with a characteristic odor, the same density. True methyl has a neutral fragrance, which is expressed rather weakly and is felt only with "sniffing", while the ethanol pairs are sharper and scribed into the nose.
It is obtained by such a product by distillation of wort, pre-lasting fermentation. You can also get it on my own at home, however, for this it is necessary to use a special distillate - a moonshine device.
Reference. The homemade moonshine, prepared from high-quality raw materials and in accordance with the technological rules, is not inferior in the quality of industrial alcohol.
But it is worth understanding that with long-term use of this ethyl product, alcoholic dependence may appear in large quantities. Therefore, all drinks prepared on its basis must be used in small quantities.
Methyl or technical alcohol, which in the people is usually simply called methanol - This is an industrial product, use it in any kind of species. Get such liquid from legna, ant alcohol and wood.
Use such a product for the manufacture of solvents and formaldehyde. When working with such a substance, it is necessary to comply with safety equipment, as methanol has a strong and caustic fragrance, and can also cause strong epidermis burns.
Reference. Technical alcohol is absorbed in the body much slower than ethanol, it destroys the nervous system, causes severe poisoning, and also worsens vision.
That is why, by studying an independent manufacture of alcoholic beverages on an alcohol basis, it is very important to use the right product.
When buying alcoholic beverages in stores with a proven reputation, the risk of poisoning "Painsen" product is significantly reduced. Most often drinks with methyl alcohol come true in stalls, shopping tents, with hands, in unauthorized points of sale and drink, as well as near the stations.
However, in order to independently determine which kind of type of alcohol is presented, it is not necessary to carry its samples into the laboratory. There are several simple ways to determine the type of alcohol:
Attention! By buying alcohol in random places or, especially, having received a homemade product as a gift, you smell it before use. If the smell seems too sharp, some unusual, do not be lazy to spend homework to prevent hard poisoning.
If methanol has yet been used, then this will be testified:
A person can also be bad oriented in space and lose consciousness. In such cases, it is immediately necessary to provide first aid:
For intoxicating and neutralizing methanol, the victim every three hours is allowed to drink 50 ml slightly diluted ethanol. But do not do home self-medication. Only in a medical institution can evaluate the degree of poisoning and provide the right assistance.
It is possible to choose ethyl alcohol if you exceed the permissible dose of use. The amount of alcohol that has fallen into the blood is measured in a ppm (‰) - a conditional unit, denoting 1/10 part of the percent of alcohol per 1 liter of blood.
If drunk is sick, it is necessary to give him the opportunity to clean the stomach as it should, at the same time, if he is able to drink water, you need to offer it in sufficient quantity. The more alcohol, the body will fail at this stage, the better. It is important to ensure that the person does not choke a drink or a vomit. The next morning after the "victim" cleans, he will need:
It should be avoided by severe physical activity, the effects of contrast temperatures, heavy food and do not "hang out".
If there are doubts about the acquired alcoholic liquid, then it is better to make several studies at the same time to determine its quality. Check out the video in which the Lang method is used is one of the simple ways with which you can check the quality of alcohol at home:

How to distinguish ethyl alcohol from methyl
Detect in the container and drink low-quality alcohol - more Polbie. It is much worse to use methyl alcohol instead of ethyl alcohol. It is very difficult to distinguish them on the eye, which leads to frequent poisoning. Methanol is the strongest poison, adversely affecting the nervous and vascular system, as well as on vision. If a person survives, then often remains blind. The adoption of methyl alcohol causes lethargy, headache, overall malaise, back pain and abdomen. Possible loss of consciousness. The use of inside from 30 to 100 ml of methanol leads to a fatal outcome.
Ethyl and methyl alcohol is absolutely identical to taste, smell and color, so it will be difficult to distinguish them a simple person. There are several methods that allow you to determine that in front of you - ethanol and methanol. If you establish the quality of alcohol you can try the ignition of the liquid.
1. Close the color of the fire. If the alcohol burns with a blue flame, then, most likely, in front of you ethanol. Methyl alcohol burns green.
2.k the People's Method includes a sample with the use of potatoes. Clean the crude potatoes and throw a small slice into the container. After a few hours, it can change its color. If it is posed, the test alcohol is methanol. In ethyl alcohol, potatoes practically does not change colors.
3. One of the most reliable ways to check the chemical affiliation of the alcohol is the formaldehyde test. Take the copper wire and run on fire. Then plunge it into the liquid. From methanol there will be a sharp unpleasant odor of formaldehyde.
Ethanol in such cases practically does not smell or smell like a weak fragrance of apples.
Applied similarly by the end result of the test methods. Moch the vaccine with alcohol, pour it out and sweat sharply. You can also add to the liquid manganese and set fire. By the above outgoing smells, determine the presence of alcohol affiliation to the ethanol group or methanol.
How to distinguish methanol from ethanol
Externally methanol (technical alcohol) is very similar to ethyl alcohol. It has about the same density and refractive coefficient (the ability to refract the sun rays). It has the same smell and color. In the laboratory conditions, the methanol from ethanol will not be larger there. At home, it is harder to do this. However, there are several ways to distinguish ethyl alcohol from methyl and without complex equipment.
You will need
- metal container (mug, turk, etc.),
- copper wire,
- Gas burner (apply a household gas stove),
- Sigdition,
- transparent dishes (glass),
- Manganese.
Instruction
The first way.
1.Product the metal container with the fluid test on the burning gas burner (stove).
2. Measure the thermometer the temperature at which the fluid will begin to throw. Methanol boils at about 64 ° C, ethanol - about 78 ° C.
The second way.
1. A small spiral from the copper wire. It is necessary to increase the surface of the contact of copper and the fluid test.
2. Rush the copper wire is doing, and better - to black: this is the degree of heat when the copper oxide begins on the surface of the wire.
3. Cover the hot wire into the cooked container with the fluid test.
4. Impedible: If the fragrance of heavy apples appeared is ethanol. If a sharp, unpleasant and irritating mucosa smell occurred is methanol.
Third way.
1. Will the test liquid into transparent dishes.
2. Add to the test liquid a bit of manganese (permanganate potassium).
3. In the liquid, gas bubbles appeared - this is methanol. If there are no bubbles and smelled with vinegar - this is ethanol.
Helpful advice
It is possible to distinguish ethanol from methanol using a iodoform reaction: when the iodine is mixed, alkali (sodium hydroxide), ethyl alcohol and heated to 50 ° C of water drops yellow precipitate - iodoform. Methanol does not give such a reaction.
Bubbles that stand out when the interaction of methanol with potassium permanganate is carbon dioxide. And during the oxidation of ethanol by mangartee, there is no gas selection - acetic acid is formed. This is used when cleaning ethanol from methyl alcohol impurities.
How to distinguish ethyl alcohol from methyl?
A terrible dilemma, in fact. More precisely, it is very scary in the end to be mistaken. After all, methanol is a terrible poison, a deadly dose is considered from 30 to 100 ml. Otherwise, a person can survive, but at the same time he will lose sight.
Therefore, we take seriously to the following information:
Ethanol during the ignition burns blue, methanol - green flame.
If you throw a piece of potatoes into a glass with alcohol, then after a few hours, it can either bring up - then this is methanol, or stay in the same color - respectively, before you ethanol.
For amateur chemists: take a copper wire, glow it, omit into a glass with alcohol. If you have methanol, the smell will be extremely unpleasant, if ethanol, then the smell will not either, or you will feel the light fragrance of apples.
To taste, color, smell methyl alcohol looks like ethyl, but
programming methods
But the most reliable way is to split the wire from copper on fire, dropping into a vessel with liquid. Methyl alcohol will go sharp unpleasant odor of formaldehyde. If the ethanol vessel, there will be no smells.
The most effective and fast way to distinguish methyl alcohol from ethyl. Pour the test liquid into a glass, take a small piece of copper wire, 0.5-1 mm. Heat this wire in the flame of the candle or gas burner, and quickly lower in a glass. Entering the reaction with alcohol, the hot copper will allocate some gas from alcohol. Its composition is not important to us. Its smell is important.
If the pairs of glass have an acidic (acid) smell, it was ethyl alcohol. And if the smell of formaldehyde, that is, a frank smell of the morgue, then in a glass was a methyl alcohol. This method is verified personally, so I recommend. Especially now, when the shelves of even branded stores are filled with fake alcohol.
If you drink a poor-quality ethyl alcohol, then poisoning can be strong, but if you use methanol, then there is very little chances to survive after that.
First of all, the ethyl alcohol from methyl is different to taste, ethyl think everyone tried alcohol as alcohol, but methyl has a chemical solution taste Alcohol smells like alcohol, but methyl chemistry and very much.
To identify the type of alcohol, you should be done in the first thing to do a lot of alcohol. Methanol with burning has a green shade, while ethanol has a blue flame color.
It is also fashionable to use for the difference between a piece of ordinary white, which halted in the methyl alcohol, the watch will take a stupid shade.
Methyl alcohol to distinguish from ethyl at home is almost impossible. The method with a heated wire and the smell of formaldehyde is good for currices of chemistry. Ethyl alcohol with this method will smell acetone, while not particularly different from formaldehyde.
A more effective way to get a moistened paper moistened and look at the flame color. Pure ethyl alcohol will burn in the first seconds in a blue flame, methanol will burn green.
By ordinary ignition in a spoon. Ethyl (drinking) alcohol burns hay-blue flame. Methanol burns with a flame greenish.
By immersion in an unknown medium of pissed plastic potatoes. An hour later in the methanol, the potatoes is poring, and the ethyl alcohol will remain the same color.
By formaldehyde sample. A piece of copper wire is splitting on fire and let go in alcohol. If it smells like apples - you can drink. If it smells like a morgue (formaldehyde) - it is impossible to drink.
The most correct thing is to hand over a sample to a chemical analysis, if there is such an opportunity. In any case, inwards do not use if there are some doubts.
There is a test with potatoes - the potato slice, left for several hours, acquires a pink shade in methyl alcohol, in ethyl color does not change ...
You can also heat the copper wire on fire, omit into the sample. Ethyl alcohol does not give a new smell, and methyl gives a sharp unpleasant smell.
Ethyl alcohol can be distinguished from methyl in the smell. Methyl alcohol has a pronounced unpleasant smell. And ethyl, simply, smells of alcohol. Just to be able to distinguish, you need to use alcohol at all. If you use alcohol, then it will be difficult to distinguish.
Even to distinguish ethyl alcohol from methyl, enough to put in a piece. If the onions green leaves, half an hour later, then it is a methyl alcohol.
