Read： 926 Time：11months ago Source：Transform the World with Simplicity

Cyclohexanone is an important organic chemical raw material, which is widely used in the production of various chemicals and polymer materials. This article will detail the properties and uses of cyclohexanone.

1. the nature of cyclohexanone

cyclohexanone is a colorless and transparent liquid with a special odor of ketone. It is insoluble in water but miscible with many organic solvents. The boiling point of cyclohexanone is 155°C, the melting point is -47°C, and the relative density is 0.9478(20/4°C). Cyclohexanone has strong reactivity and can react with many compounds such as addition, condensation and oxidation.

2. The use of cyclohexanone

1. Production of nylon and engineering plastics

Cyclohexanone is an important raw material for the production of nylon and engineering plastics. It reacts with hexamethylene diamine to produce nylon 66 salt, which can be further processed to obtain nylon 66 fiber and engineering plastics. Nylon 66 has excellent properties such as high strength, wear resistance and heat resistance, and is widely used in the manufacture of mechanical parts, auto parts, electrical insulation materials, etc.

2. Production of solvents and coating

Cyclohexanone can be used as a solvent for the manufacture of coatings, inks, adhesives, etc. Compared with other solvents, it has higher solubility and lower volatility, so it is widely used in the coating industry.

3. Production of plasticizer

Cyclohexanone can be used as a raw material for the production of plasticizers for the manufacture of dioctyl phthalate (DOP) and other plasticizers. Plasticizers can be added to plastics to increase their flexibility, ductility and processability.

4. Production of pesticides and pharmaceutical intermediates

Cyclohexanone can also be used as raw materials for the production of pesticides and pharmaceutical intermediates for the manufacture of fungicides, herbicides, pesticides and pharmaceutical intermediates.

In conclusion, as an important organic chemical raw material, cyclohexanone has a wide range of applications in the field of chemical production raw materials.
