Nitrocyclohexane, manufacture

The only other nitroparaffin manufactured on a large scale was nitrocyclohexane [1122-60-7] made by Hquid-phase nitration of cyclohexane. Nitrocyclohexane was the starting material for S-caprolactam via reduction to cyclohexanone oxime. This process has been superseded by other, more efficient processes (see Caprolactam). Nitrocyclohexane is not being produced ia large quantities for either captive use or sale. 

Nixan [Nitrocyclohexane] A process for making cyclohexane oxime (an intermediate in the manufacture of nylon) from benzene by liquid phase nitration, followed by hydrogenation of the nitrobenzene. Invented by Du Pont and operated from 1963 to 1967. 

Nitroalkanes. A process was developed and operated for a time for the manufacture of s-caprolactam based on the nitration of cyclohexane.197 Nitrocyclohexane thus prepared was transformed to e-caprolactam via cyclohexanone oxime. At present the only industrial process to produce nitroalkanes by direct nitration is the manufacture of nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. 

OTHER COMMENTS used as a solvent for cellulose ethers, fats, oils, waxes, bitumens, resins, lacquers, and crude rubber paint and varnish remover used in the manufacture of adipic acid, benzene, cyclohexyl chloride, nitrocyclohexane, cyclohexanol, and cyclohexanone useful in the manufacture of nylon and solid fuels may also be used in the industrial recrystalli-zation of steroids.
