AN IMPROVED PROCESS FOR THE PRODUCTION OF AN OXIME BY CONVERSION OF A BIS-(NITROSOHYDROCARBON) WHICH COMPRISES SATURATING AT A TEMPERATURE NOT IN EXCESS OF 60* C. A SOLUTION OF A BIS-(NITROSOHYDROCARBON) SELECTED FROM THE CLASS CONSISTING OF DIMERIC SECONDARY MONO-NITROSO-DERIVATIVES OF SATURATED ALIPHATICV AND CYCLO ALIPHATIC HYDROCARBONS IN AN INERT SOLVENT WITH A DRY HYDROGEN HALIDE SELECTED FROM THE CLASS CONSISTING OF HYDROGEN CHLORIDE AND BROMIDE, AND NEUTRALIZING THE OXIME HYDROHALIDE FORMED.
