摘要： This invention is addressed to a new and improved method for inhibiting the decomposition of 1,1,1,2-tetrachloroethane and an inhibited composition formed thereby wherein an inhibitor consisting essentially of an aliphatic aldehyde, an aromatic aldehyde, chlorinated derivatives of the foregoing aldehydes which are soluble in 1,1,1,2-tetrachloroethane with other chlorinated solvents, or cyclic trimers of aliphatic aldehydes and mixtures thereof, and an organic phosphorus compound are added to a solvent composition containing 1,1,1,2tetrachloroethane.

摘要： Disclosed is a process for producing highly pure chlorinated alkane in which a chlorinated alkene is contacted with chlorine in a reaction zone to produce a reaction mixture containing the chlorinated alkane and the chlorinated alkene, and extracting a portion of the reaction mixture from the reaction zone, wherein the molar ratio of chlorinated alkane:chlorinated alkene in the reaction mixture extracted from the reaction zone does not exceed 95:5.

摘要： The present invention provides processes for the production of chlorinated methanes via the direct chlorination of methane. The processes include a dehydrochlorination and/or chlorination step that converts up to 100% of the higher chlorinated alkanes in a process stream from the methane chlorination reaction into more highly chlorinated alkanes. These more highly chlorinated alkanes can be easily removed from the process stream. The use of a cost effective feedstream of crude methane is thus rendered possible, without additional capital expenditure for the sophisticated separation equipment required to separate ethane and other hydrocarbon components from the methane feed.
