Abstract

In a process for the production of ketoxime hydrochlorides by the action of nitrosating agents on aliphatic, araliphatic or cycloaliphatic hydrocarbons in the presence of actinic light, the light source is coated with an uninterrupted coherent layer of a substance in a solid form deposited by crystallisation or sublimation, this substance being the hydrocarbon reactant or an inert organic compound soluble in the reaction mixture. This coating on the light source is said to prevent the formation of a yellow-brown coloured coating upon the light source, thus preventing any decrease in the transmission of light from the source. The thickness of the crystal coating may be from 0.1 to 1.0 cm. The temperature of the reaction is maintained in the range of -30 DEG to +40 DEG C. and a temperature gradient is maintained between the light source and the reaction medium such that the crystal coating is preserved throughout the reaction. A suitable light source is an 80 watt mercury lamp providing light of wave length 200 mm to 600mm . Nitrosating agents specified are nitrosyl chloride, nitrogen monoxide and chloride, alkyl nitrites and hydrochloric acid, nitrous gases and hydrochloric acid, and nitrosylsulphuric acid and hydrochloric acid. Hydrocarbons specified as starting materials are n-hexane, n-heptane, toluene, ethylbenzene, xylenes, cyclopentane, fluorene, cyclohexane, decahydronaphthalene, cycloheptane, cyclooctane and cyclododecane; and they may be dissolved in inert solvents such as benzene, carbon tetrachloride, chloroform or monochlorobenzene. Inert organic compounds suitable for the crystal coating are naphthalene, anthracene or hexachlorethane. Four examples are given, illustrating the difference in yield and purity of ketoxime hydrochloride obtained when the reaction is carried out with and without the crystal coating on the light source. In Examples 1, 2 and 3, the crystal coatings are of cyclohexane, cyclooctane and cyclododecane respectively, and, in Example 4, a crystal coating of naphthalene is used when treating decahydronaphthalene with nitrosating agents.
