Chemical properties:
Cyclohexanone is flammable and may cause combustion when exposed to high heat or open flame. It will react violently when in contact with oxidants. If exposed to high heat, the internal pressure of the container will increase, and there is a risk of cracking and explosion. It is the same as open-chain saturated ketones. It can produce adipic acid HOOC(CH2)4COOH when oxidized with air, oxygen or nitric acid in the presence of a catalyst. Cyclohexanone oxime rearranges to form caprolactam under the action of acid. They are the raw materials for making nylon 66 and nylon 6 respectively. Cyclohexanone is prone to self-condensation reaction in the presence of alkali; it is also easy to react with acetylene. It was first obtained by dry distillation of calcium pimelate. The large-scale production of cyclohexanone is a method of catalytic hydrogenation of phenol and then oxidation.
Main uses:
Cyclohexanone is an important chemical raw material and industrial solvent, and is the main intermediate for the manufacture of nylon, caprolactam and adipic acid. It is also an important industrial solvent, such as used in paints, especially those containing nitrocellulose, vinyl chloride polymers and their copolymers or methacrylate polymers. It is used as an excellent solvent for pesticides such as organophosphorus insecticides and many similar pesticides, as a solvent for dyes, as a viscous solvent for piston-type aviation lubricants, and as a solvent for grease, wax and rubber. It is also used as a leveling agent for dyeing and matte silk, a degreasing agent for polishing metals, and for wood coloring and painting. Cyclohexanone can be used for film removal, stain removal and spot removal.
