Description and Uses

Cyclohexanone, a colorless liquid is a cyclic ketone. It is an important building block for the synthesis of a variety of organic compounds. Majority of the cyclohexanone synthesized is utilized as an intermediate in the synthesis of nylon.
Used as a polyvinyl chloride (PVC) solvent, cyclohexanone caused contact dermatitis in a woman manufacturing PVC fluidotherapy bags. Cyclohexanone probably does not cross react with cyclohexanone resin. A cyclohexanone-derived resin used in paints and varnishes caused contact dermatitis in painters.

Cyclohexanone is used in the productionof adipic acid for making nylon; in thepreparation of cyclohexanone resins; and asa solvent for nitrocellulose, cellulose acetate,resins, fats, waxes, shellac, rubber, and DDT..
