Abstract

Ketoximes are prepared by reacting saturated hydrocarbons with nitric oxide and chlorine, while irradiating the reactants with light of wavelength 4875 or less, under substantially anhydrous and oxygen-free conditions at a temperature below 15 DEG C. Unsubstituted mononuclear alicyclic hydrocarbons, e.g. cyclohexane and cyclododecane are preferred and the reaction is preferably carried out in the liquid phase, with the hydrocarbon dissolved in a solvent such as carbon tetrachloride, either batchwise or continuously with recirculation. The ketoxime product may be in the form of hydrochloride and may be used to prepare lactams by the Beckmann reaction.
