Benzyl alcohol, chemical formula C7H8O, belongs to the representative of benzene in organic compounds, is a common organic compound. Because of its special physical and chemical properties, benzyl alcohol is widely used in many scientific research fields. This article will introduce the chemical properties, preparation methods and applications of benzyl alcohol, as well as the potential risks that may be caused by the incentives.

1. chemical properties

benzyl alcohol is white or colorless crystalline on the outside, with boiling point and melting point. It has a volatile, easy to dissolve in ethanol, ether, chloroform and benzene and other solvents of the physical properties. Benzyl alcohol can react with some acids and bases to produce salts and water. In addition, benzyl alcohol can be reacted with some organic compounds, such as HNO3/H2SO4 for nitration reaction, can get the corresponding benzyl nitrate. Some special functions of benzyl alcohol make it widely used in the fields of medicine, fine chemical industry and cosmetics.

2. preparation method

benzyl alcohol preparation method is more diversified, the most commonly used method is hydrogenation reduction method. An organic compound such as acetophenone, isophthaldione or phenol is added to a reactor in which a potassium sodium methanol solution is used, and then hydrogen gas is applied to prepare benzyl alcohol. In addition, under natural conditions, benzyl alcohol can also be prepared by nitration reaction, which is one of the most widely used inorganic chemical reactions.

3. Application

Benzyl alcohol is a commonly used chemical reagent, which can be used in the manufacture of fungicides, catalysts, preservatives, fragrances, cosmetics, dyes, resins, etc. In addition, benzyl alcohol can also make cephalosporins and other drugs. Due to the volatile physical properties of benzyl alcohol, it can be used to manufacture hypnosis, anesthesia and other drugs, and become one of the components of the well-known "fentanyl.

4. incentives may cause potential risk

Although benzyl alcohol has a wide range of applications, it is necessary to pay attention to the possible risks of benzyl alcohol in actual use. First of all, benzyl alcohol is an organic compound. If it is exposed to the outdoor environment for a long time, it is very likely to be degraded by natural light and produce some toxic compounds. Second, the volatile nature of benzyl alcohol is also dangerous, and contact with the eyes, skin or other healthy tissue may cause pathological damage or chemical burns.

summary:

This paper introduces the chemical properties, preparation methods, application fields and potential risks of benzyl alcohol in detail. As a common organic compound, benzyl alcohol has its effects in many fields. But its potential dangers have also attracted our attention, so remember to pay attention to its safe use and storage methods during use.
