Abstract
Cycloaliphatic ketoximes and their hydrochlorides are prepared by the reaction of cycloaliphatic hydrocarbons with nitrosyl chloride in the presence of added hydrogen chloride and/or nitric oxide while irradiating with light to form the hydrochlorides and, if required, treating the hydrochlorides with an inorganic base to form the free ketoximes. Suitable cycloaliphatic hydrocarbons are cyclopentane, cyclohexane, cycloheptane and cyclo-octane and their alkyl substituted derivatives. The process may be carried out at a temperature varying from - 50 DEG C. to 40 DEG C. The hydrogen chloride may be dissolved in the hydrocarbon with nitrosyl chloride, or a mixture of nitrosyl chloride and hydrogen chloride may be pumped through the hydrocarbon. The nitric oxide is preferably pumped with nitrosyl chloride through the hydrocarbon, and hydrogen chloride may be mixed with the nitric oxide. In the examples cyclopentanone oxime, cyclohexanone oxime, cyclo-octanone oxime and isomeric ketodecahydronaphthalene oximes and their hydrochlorides are prepared.
