How to produce acetic acid and its uses.

How to produce acetic acid can be answered in three steps. Acetic acid is produced by the oxidation of ethanol, the key raw material. We need to have a complete and efficient process in order to produce acetic acid. There are many different ways to produce acetic acid, including high temperature chemical synthesis reaction, low-temperature chemical synthesis reaction and biological synthesis reaction. In general, the high-temperature chemical reaction is mainly used for industrial production process while low-temperature or biological reactions are mainly used for research or small production in laboratory .

Physical properties of acetic acid

1. It is a colourless liquid.

This compound is a colourless liquid, density is 0.9899g/cm³, boiling point is 118.1 ℃(lit.), melting point is -56.9 ℃, flash point is 25.4 ℃. It is a volatile organic compound with a very bad toxicity. Acetic acid is soluble in water and ethanol. Acetic acid is composed of the carbon, hydrogen and oxygen atoms, which can be wholely decomposed into CO₂ and H₂O in the laboratory. It is known as acetic acid "acid" because it exists in our body naturally, but also as real acid because it reacts with metal and alkalis to form salts such as strong acids (such as hydriodic acid), alkali metal chlorides (such as sodium chloride) etc..

2. It is a colourless and transparent liquid at normal temperature (25℃).

Acetic acid is the simplest carboxylic acid, has a very strong smell, the melting point of -56.9℃, the boiling point is 391 K, relative density is 0.92.1 to 0.94g/cm³, decomposition point: -8℃, specific gravity: 1.042-1.048g/cm³ at 26℃. It is a strong acid, less soluble in water (15mg/100mL) is almost insoluble in ethanol (30mg/100mL). Acetic acid has a weight of about 30g, viscosity 1.1mP·s, density 1.036g/cm³. It has no smell or taste. Acetic acid can be used directly for dilution without cooling. This is how to how to produce acetic acid.

3. Its density in liquid form is 1.049 g/cm³.

This compound is a liquid with a freezing point of -56.9 viscosity 0.3mPa·s optical rotation +178 melting point of 38. Acetyl chloride (salt 1-chloro-2-acetyl-) is a kind of solvent and neutralizing agent. It has the following characteristics:

1. Acetyl chloride is very soluble in ethanol, ethyl acetate is usually used to dilute this compound. Solubility, solubility in water is not so good, it has strong corrosive properties, many new ways can be used to solve this problem.

2. Acetyl chloride is a polar solvent, its peculiar method of work.

3. Acetyl chloride breaks down in the presence of acid or alkali, get acetate and other products, which make it easy to work with various acids and bases, generally used for esterification and decomposition reactions.

4. It's corrosive and has good performance in neutralizing strong acids such as HCl and HNO₃; it accelerates decomposition of benzene, phenol; it used to remove phenolic compounds such as rusts from the steel etc. It is also a professional neutralizing agent; it can be used as a degreaser, detergent and washing agent.

Uses of acetic acid

1. It is mainly used to make acetone and acetic acid.

Acetic acid is mainly used to produce acetone and acetic acid through oxidation of ethanol, the key raw material. Acetone is sold as a solvent, the largest consumer being the food industry. Acetaldehyde (ethanol) oxidation reaction produces acetaldehyde and other chemicals, but also release heat as a byproduct. With microorganisms made up in the reaction mixture, it will turn into acetaldehyde gas bacteria produce using microorganisms such as bacteria or yeast decomposition, and then oxygen-free reaction mechanism by using air during the process of oxidation to produce acetic acid .

2. It is used in chemical industries.

According to Chemical Safety and Environmental Protection Act, the Department of Industrial Hygiene Inspection, the Hubei Department of Construction, Qingan Chemical Co., Ltd. is registered as a chemical agent manufacturer. Acetic acid is used as a solvent for production of other chemicals, so it also has to be treated with care; In addition to the above-mentioned uses, it also has many special applications such as paint solvents and photographic chemicals. In addition, it is also one of the important raw materials used in artificial leather production.

In conclusion, the production and properties of acetic acid can be answered by three steps. Acetic acid is produced by the oxidation of ethanol, key raw material. There are many different ways to produce acetic acid, including high temperature chemical synthesis reaction, low-temperature chemical synthesis reaction and biological synthesis reaction. In general, the high-temperature chemical reaction is mainly used for industrial production process while low-temperature or biological reactions are mainly used for research or small production in laboratory . This explains how to produce acetic acid.
