1. There is a difference between alcohol, industrial alcohol and medical alcohol. Mainly in e68a8462616964757a686964616f31333361303031

Ethanol concentration content and range of use are different:

1. Ethanol concentration content is different

1) Industrial alcohol contains 96% ethanol and 1% methanol;

2) The edible alcohol content is not greater than methanol;

3) Medical alcohol is also edible alcohol, but the ethanol content is 75%.

2. Different uses:

1) Industrial alcohol can only be used as a raw material or as a fuel in the non-edible chemical industry;

2) Edible alcohol is mainly used in the food industry;

3) Medicinal alcohol can be used in the production of drugs, and can also be diluted into 75% medical disinfection alcohol in proportion.

2. The concept of alcohol, industrial alcohol and medical alcohol:

1. Edible alcohol (edible alcohol, also known as fermented distilled spirit, is mainly the use of potatoes, grains, sugar as raw materials through cooking, saccharification, fermentation and other processing for the food industry to obtain hydrous alcohol, its flavor characteristics are divided into four parts: color, aroma, taste, body, that is, refers to the content of aldehydes, acids, esters, alcohols in the distilled spirit, different flavors and gases will make the flavor of distilled spirits different.

2. Medical alcohol, commonly known as ethanol, is made from corn or other grains by saccharification enzyme fermentation, with few impurities. Consists of 75% alcohol and 25% water (chemical formula:

c2h5oh） 。Medical and medicinal alcohols are products that meet the requirements of edible alcohol at this stage, and there are no special ones.

3. Industrial alcohol, commonly known as methanol: it is extracted from raw coal or petroleum, contains a large amount of methanol, formaldehyde and other impurities, and is not easy to separate, and is composed of 95% ethanol and 5% methanol and formaldehyde (chemical formula: CH3OH) Industrial alcohol must not be taken or used for the disinfection of the human body because it contains methanol and other harmful substances to the human body, because methanol will cause poisoning, and some of it will be absorbed for disinfection, and it can lead to blindness and death after poisoning.

The difference between edible alcohol, medical alcohol and industrial alcohol is considered a long time to see today.

Industrial alcohol contains methanol, which is toxic. Medical treatment is not.

Does leaf alcohol remove the smell of polyurethane? Can pharmaceutical alcohol get rid of the smell that actually refers to it?

The degrees are different, how much, I forget.

Yes, industrial impurity, medical purity.

(2012 New Curriculum Standard) The concentration of medical alcohol is usually 75%.

The main differences are, different purity, different toxicity, and different uses, as follows:

First, the purity is different.

1. Industrial alcohol.

The purity of industrial alcohol is generally 95% and 99%.

2. Medical alcohol.

There are many purities of medical alcohol, the common ones are 95% and 75%.

3. Edible alcohol.

The degree of edible alcohol is uncertain, and the purity of edible alcohol is usually 95%.

Second, the toxicity is different.

1. Industrial alcohol.

It cannot be used for disinfection of the human body, because methanol can cause poisoning.

2. Medical alcohol.

Alcohol can be used to disinfect the human body due to its low concentration.

3. Edible alcohol.

It is mainly obtained by using potatoes, grains and sugars as raw materials through cooking, saccharification, fermentation and other treatments for the food industry, and there is no toxicity.

Third, the use is different.

1. Industrial alcohol.

It is mainly used in industrial printing, electronics, hardware, spices, chemical synthesis, pharmaceutical synthesis, etc. It can also be used as a cleaning agent and solvent.

2. Medical alcohol.

It is mainly used for disinfection and sterilization.

3. Edible alcohol.

It is mainly used in the food industry.

1. Ethanol concentration content is different

1) Industrial alcohol contains 96% ethanol and 1% methanol;

2) Medical alcohol is also edible alcohol, but the ethanol content is 75%.

2. Different uses:

1) Industrial alcohol can only be used as a raw material or as a fuel in the non-edible chemical industry;

2) Medical alcohol can be used in the production of medicines, and can also be diluted into 75% medical disinfection alcohol in proportion.

3. The preparation of raw materials and processes are different

Industrial alcohol is made by cracking raw coal or petroleum, which contains a large amount of methanol, formaldehyde and other impurities, and is not easy to separate;

Medical and medicinal alcohols are now made by saccharification enzymatic fermentation of corn or other grains with few impurities.

4. Commonly known as different:

Industrial alcohol is commonly known as methanol;

Medical alcohol is commonly known as ethanol.
