Cyclohexane use and production method
Mainly used in the manufacture of cyclohexanol, cyclohexanone, widely used as a solvent in the coating industry
Used as a solvent, also used for organic synthesis
Extraction solvent; Pigment thinner.
Most of cyclohexane is used to make adipic acid, caprolactam and hexamethylene diamine (98% of total consumption), a small part is used to make cyclohexylamine and other aspects, such as cellulose ethers, fats, oils Solvents for waxes, asphalts, resins, and rubbers; organic and recrystallization media; paint and varnish removers. It can be used as a raw material for nylon 6 and nylon 66. It can also be used as a polymerization diluent, paint stripper, detergent, adipic acid extractant and binder.
Analytical determination of molecular weight, solvent, recrystallization of steroids, organic synthesis (cyclohexanol, cyclohexanone), complexometric titration of copper, iron, silicon, aluminum, calcium and magnesium.
Almost all cyclohexanes are currently produced by the hydrogenation of pure benzene, and only Phillips produces fractions of the cyclohexane-rich fraction. There are many methods for hydrogenating benzene to cyclohexane, and the only difference lies in the difference in catalyst, operating conditions, reactor type, and heat removal method. Usually divided into two kinds of liquid phase method and gas phase method, and the majority of the liquid phase method. The benzene hydrogenation process can be divided into: (1) Liquid phase hydrogenation of benzene (IFP process in France) (2) Benzene gas phase hydrogenation (ie, Dutch DSM process) (3) Liquid phase hydrogenation of benzene (UOP'SHydrar process)
Catalyzed by benzene derived hydrogenation.
Separated from crude oil.
