Abstract: 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.

Abstract: A catalyst, such as FeCl.sub.3, useful in the production of chlorinated hydrocarbons such as 1,1-dichloroethane is removed from the effluent of a process reactor and recycled. Hydrochloric acid is removed from the process stream resulting in the catalyst present in the process stream in solution precipitating out of solution. Then it can be removed from the process stream by conventional separation techniques. Alternatively, the catalyst present in the process stream as a solid, without the removal of HCl, is separated from the liquid present by means of a cyclone and recycled. In both cases, the catalyst retains its catalytic activity.

Abstract: 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.
