Cyclohexanone CAS# 108-94-1

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, such as for paints, especially for those containing nitrocellulose, vinyl chloride polymers, and their copolymers or methacrylate polymer paints, etc. It is used as an excellent solvent for pesticides such as organophosphorus insecticide and many analogs, 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 an equalizer for dyeing and fading silk, a degreasing agent for polishing metal, and lacquer for wood coloring. Used as a high boiling point solvent for nail polish and other cosmetics. It is usually formulated with low boiling point solvents and medium boiling point solvents to form mixed solvents to obtain a suitable evaporation rate and viscosity. Cyclohexanone is a very widely used petrochemical raw material, but also an important organic solvent, cyclohexanone according to its use is often divided into two categories: amide and non-amide. Cyclohexanone for amides is mainly used to manufacture caprolactam and adipic acid, both of which are important raw materials for the manufacture of fiber PA6 and engineering plastic PA66. At the same time, cyclohexanone is an important industrial solvent and can also be used to produce pharmaceutical intermediates. At present, there are three main production methods of cyclohexanone: cyclohexane oxidation, phenol hydrogenation, and cyclohexene hydration. Phenol hydrogenation was the first process applied to the industrial production of cyclohexanone, and Chemicalbook has two oxidation routes for cyclohexane oxidation in industrial production, one for catalytic oxidation and the other for non-catalytic oxidation. The catalytic oxidation process mainly uses cobalt salts, boric acid, or metaboric acid as catalysts. 1980s Japan Asahi Kasei developed the cyclohexene hydration process for cyclohexanol. This process is based on the incomplete hydrogenation reaction of benzene as raw material to prepare cyclohexene, and cyclohexene hydration to produce cyclohexanol, with cyclohexane as a by-product in the route. The process has low consumption and effectively avoids the waste alkali generated during the cyclohexane oxidation process, which reduces the environmental pressure and has obvious prospects.
