Benzyl alcohol is an important organic chemical raw material, which is widely used in medicine, spices, dyes, plastics and synthetic fibers. This article will detail the properties and uses of benzyl alcohol.

1. the nature of benzyl alcohol

benzyl alcohol is a colorless and transparent, aromatic smell of liquid, molecular formula is C6H5CH2OH, structural formula is C6H5-CH2-OH, relative molecular mass is 108.14. Benzyl alcohol has a strong alcohol taste and aromatic smell of benzene ring, insoluble in water, but miscible with alcohol, ether, acetone and other organic solvents.

benzyl alcohol has a boiling point of 205°C, a melting point of -15.3°C and a flash point of 101°C. After the vapor of benzyl alcohol is mixed with air, it can form an explosive mixture, which can cause combustion and explosion when exposed to open flame and high heat. Therefore, special attention should be paid to safety during storage and use.

benzyl alcohol has strong reducibility and is easily oxidized to benzoic acid. In addition, benzyl alcohol also has the characteristics of alcohol hydroxyl group, can occur esterification, etherification, halogenation and other reactions.

2. the use of benzyl alcohol

1.

in the field of medicine Benzyl alcohol has a wide range of applications in the field of medicine, commonly used as intermediates in drug synthesis. For example, benzyl alcohol can be used to synthesize drugs such as antibacterial drugs, anti-inflammatory drugs, and anti-cancer drugs. In addition, benzyl alcohol can also be used as an anesthetic, a bactericide, etc.

2.

in the field of spices Benzyl alcohol has a strong aromatic odor and can be used to prepare various flavors, such as rose oil, jasmine oil, etc. In the food industry, benzyl alcohol can be used as a food additive to give food an aromatic flavor.

3.

in the field of dyes Benzyl alcohol can be used as an intermediate in the synthesis of dyes for the production of various dyes. For example, benzyl alcohol can be used in the synthesis of acid dyes, direct dyes, disperse dyes, etc.

4.

in the field of plastics and synthetic fibers Benzyl alcohol can be used as a monomer for plastics and synthetic fibers for the production of various polymers. For example, benzyl alcohol can be used to produce polystyrene, polyester and other plastic materials, as well as polyester, nylon and other synthetic fibers.

In short, benzyl alcohol as an important organic chemical raw materials, in medicine, spices, dyes, plastics and synthetic fibers and other fields have a wide range of applications. With the continuous development of science and technology, the application field of benzyl alcohol will continue to expand.
