Role and use
Cyclohexanone is an important chemical raw material and is a major intermediate in the manufacture of nylon, caprolactam and adipic acid. It is also an important industrial solvent, for example for paints, especially those containing nitrocellulose, vinyl chloride polymers and their copolymers or methacrylate polymer paints. Excellent solvent for pesticides such as organophosphorus insecticides and many analogues, used as a solvent for dyes, as a viscous solvent for piston type aviation lubricants, grease, wax and rubber. Also used as a homogenising agent for dyeing and fading silk, degreasing agent for polishing metal, wood staining and painting, available as cyclohexanone for film removal, decontamination and spot removal. Cyclohexanone and cyanoacetic acid condensation to cyclohexyl fork cyanoacetic acid, then by elimination, decarboxylation to cyclohexene acetonitrile, and finally by hydrogenation to get cyclohexene ethylamine [3399-73-3], cyclohexene ethylamine is the intermediate of drugs cough Meche, Temaren, etc..

Used as a high boiling point solvent for cosmetics such as nail polish. Usually blended with low and medium boiling solvents to obtain the right evaporation rate and viscosity.
