Read： 1271 Time：14months ago Source：Transform the World with Simplicity

Cyclohexylamine is an important organic chemical raw material, which is widely used in the synthesis of various chemical products and drugs. This article will detail the properties and uses of cyclohexylamine.

1. the nature of cyclohexylamine

cyclohexylamine is a colorless transparent liquid with ammonia smell. It is easily soluble in organic solvents such as water, ethanol and ether, but insoluble in non-polar solvents such as benzene and petroleum ether. Cyclohexylamine is highly alkaline and can react with acids to form salts.

cyclohexylamine has a high boiling point, it can be distilled and separated at high temperature. In addition, it also has good thermal stability and chemical stability, and can be used in a wide pH range.

2. the use of cyclohexylamine

1. synthetic pesticide

cyclohexylamine can be used to synthesize a variety of pesticides, such as fungicides, insecticides and herbicides. For example, the reaction of cyclohexylamine and formaldehyde can generate cyclohexenone, which is a broad-spectrum fungicide with good control effect on a variety of plant pathogens.

2. synthesis of pharmaceutical intermediates

cyclohexylamine can be used as pharmaceutical intermediates for the synthesis of a variety of drugs. For example, it reacts with acetic anhydride to produce acetylcyclohexylamine, an important intermediate for analgesic and antipyretic drugs.

3. Synthetic rubber accelerator

Cyclohexylamine can be used as a rubber accelerator to improve the processability and vulcanization speed of rubber. It reacts with tetramethylthiuram disulfide to produce a commonly used rubber accelerator, TMTD.

4. Synthesis of dyes

Cyclohexylamine can be used to synthesize a variety of dyes, such as acid dyes, direct dyes and disperse dyes. It reacts with phenol and formaldehyde to produce a black disperse dye.

In conclusion, as an important organic chemical raw material, cyclohexylamine has been widely used in the fields of pesticides, pharmaceuticals, rubber and dyes.
