How to distinguish between industrial alcohol and edible wine

2. Industrial alcohol.

The first part of the microbial method can be glucose hydrolyzed with starch or cellulose.

The fungi are anaerobically fermented into alcohol, and then distilled, which is similar to edible wine; Ethylene hydration method (addition with water), C2H4 H2O catalyzes C2H5OH. These two methods are the most commonly used methods in industry, and the initial product of industrial alcohol is non-toxic. However, because industrial alcohol is not easy to supervise with fake wine, China's relevant regulations:

Methanol must be added to industrial alcohol.

3. Edible alcohol.

The difference with industrial alcohol is that the former is generally obtained by grain fermentation, while industrial alcohol is mostly synthesized from petroleum. Industrial alcohol contains ingredients that are harmful to the human body, such as methanol (but it has no effect when used in industry). The fermentation of edible alcohol is similar to the traditional brewing technique, so the resulting alcohol does not contain harmful ingredients to the human body, so it is edible.

Edible alcohol can be used industrially, but at a higher cost. Industrial alcohol cannot be used for consumption.

Insulating varnish. Washing water, cleaning agent.

industrial alcohol, etc. With the expansion of the market and the improvement of product quality, the scale of the company has grown one after another. Since the products were put on the market, they have generally won the trust and praise of customers, and have become a leader in the petrochemical solvent industry at home and abroad.

Industrial alcohol is anhydrous methanol or crude methanol has obvious odor, edible alcohol is ethanol and the taste is much lighter, if there are precision electronic scales around, take two samples of the same capacity simple specific gravity (ethanol is heavier than methanol, in the absence of reagents, use molar mass for rough identification, provided that these two solvents are not diluted with water).

It can be seen with a simple naked eye. Industrial alcohol is yellowish. Alcohol is mostly colorless. Smelling the smell with your nose can also be asked. Industrial alcohol has a five-egg stinking smell. Whereas edible alcohol does not.

You can see the color of the solution: the color of industrial alcohol is pale yellow, and the color of edible alcohol is colorless; It can also be done by smelling the smell: industrial alcohol stinks slightly.

It is not discernible by appearance and smell, but can only be distinguished by instrumental analysis. As for those who say that the color of the industry is yellow, these are basically the best materials, and they are not seriously processed, rather than normal production.

Edible alcohol: made from grains, potatoes, molasses or other edible crops as the main raw materials, fermented and distilled. It contains a lot of aldehydes and has a spicy taste.

Industrial alcohol, that is, alcohol used in industry, also known as denatured alcohol, industrial alcohol. Ethanol is of high purity and low in aldehydes, so the taste will be a little sweet.

The main component of industrial alcohol and edible alcohol is ethanol. Industrial alcohol may be higher in methanol and other substances, but it also depends on the product grade. Due to process problems, edible alcohol may have more esters, and it also depends on the product grade.

For most people, it is impossible to distinguish by the senses. Special analytical instruments, such as chromatographs, can be used to analyze the distinction of special lipids other than ethanol.

On the surface, it must not be visible. Both industrial and edible alcohol are essentially the same color in appearance. It is best to identify according to the label when buying. And compared to using a hotel, industrial alcohol** will be cheaper.

The difference between edible alcohol and industrial alcohol is that the former is generally obtained by grain fermentation, while the latter is mostly synthesized from petroleum. Identification can be made with the help of professional laboratory tests.

Edible alcohol: starch hydrolyzes glucose, yeast and other fungi glucose is fermented anaerobically to produce a mixture of low-concentration alcohol, bacteria and raw materials, and then distilled to obtain alcohol, and different concentrations are different degrees of wine.

Industrial alcohol: The first part of the microbial method can be used to ferment glucose bacteria hydrolyzed with starch or cellulose into alcohol anaerobically, and then distilled, which is similar to edible wine; Ethylene hydration method (addition with water), C2H4 H2O....Catalysis....c2h5oh。These two methods are the most commonly used methods in industry, and the initial product of industrial alcohol is non-toxic.

Distinction: 1. The difference between industrial alcohol and alcohol can be seen in the boiling point of boiling envy, the boiling point of ordinary alcohol is 75 degrees Celsius, and the boiling point of industrial alcohol is 65 degrees Celsius.

2. Take two test tubes, load them with pure methanol (industrial alcohol) and ethanol (ordinary alcohol), roll the fine copper wire into a spring shape and burn it on the alcohol lamp, and soon, it is found that the original red copper wire oxidizes and turns black, at this time, quickly stretch it into the liquid in the test tube, the copper wire returns to red and stares, and the alcohol hydroxyl group is oxidized into an aldehyde group. Ethanol oxidized to acetaldehyde, which has a pungent odor, and methanol oxidized to formaldehyde, which bubbles in addition to having a pungent odor because formaldehyde is a gas.

1. The chemical composition of wine is ethanol, which is commonly known as alcohol, which generally contains trace amounts of fusel and esters, but does not contain formaldehyde. The concentration of edible liquor is generally below 60 degrees (i.e. 60%) (a few have more than 60 degrees), and the liquor is purified to more than 75% industrial alcohol by fractionation, and purified to absolute ethanol. Edible wine is a kind of health drink, and moderate consumption can promote blood circulation, activate meridians, and dispel rheumatism.

2. Industrial alcohol, that is, the alcohol used in industry, also known as denatured alcohol and industrial fire wine, the purity of industrial alcohol is generally 95% and 99%, and it contains formaldehyde. Industrial alcohol is mainly produced in two ways: synthesis and brewing (corn or cassava), the general cost of synthesis is low, and the methanol content is high, so it is cheaper; The brewed industrial alcohol generally has an ethanol content greater than or equal to 95%, and a methanol content lower than that, which is more expensive.

3. Industrial alcohol methanol has strong toxicity, which has the greatest impact on the nervous system and blood system of the human body, and it will produce toxic reactions through the digestive tract, respiratory tract or ** ingestion, and methanol vapor can damage the mucous membrane and vision of the human respiratory tract. Poisoning reactions will occur when the intake of more than 4 grams of methanol is consumed, and a small cup of more than 10 grams can cause blindness in both eyes, and death can occur when the amount is consumed. The lethal dose is more than 30 ml, methanol is not easy to be excreted in the body, it will accumulate, and it is also toxic to oxidize to form formaldehyde and formic acid in the body.
