| titleOfInvention | PROCEDURE TO PREPARE CYCLOALKANONOXYMES |
| abstract | Cycloalkanone oximes are prepared without the use of ultra-violet radiant energy by treating a cycloaliphatic hydrocarbon with a nitrosyl halide, or with an oxide of nitrogen in the presence of a halogen and (or) a nitrosyl halide. at a high temperature for a time between 0À1 and 10 seconds. The reaction temperature may be 150-650 C., preferably 200-450 C. The presence of a hydrogen halide and (or) water vapour promotes the reaction. Examples are given of the manufacture of cyclohexanone oxime from cyclohexane, nitric oxide and chlorine, and from cyclohexane and nitrosyl chloride, in the presence of water vapour or hydrogen chloride, some bis(nitrocyclohexane), chlorocyclohexane, nitrocyclohexane, cyclohexyl nitrate, and 1,1-dichlorocyclohexane being also obtained as by-products. Reference is made also to the manufacture of oximes from cyclopentane, cycloheptane, cyclooctane, cyclododecane and methylcyclohexane.Cycloalkanone oximes are prepared without the use of ultra-violet radiant energy by treating a cycloaliphatic hydrocarbon with a nitrosyl halide, or with an oxide of nitrogen in the presence of a halogen and (or) a nitrosyl halide, at a high temperature for a time between 0.1 and 10 seconds.
