Abstract: A continuous process is provided for the manufacture of haloalkanes by the reaction of carbon tetrachloride with olefins in the presence of iron metal, trialkylphosphate, and ferric chloride. A fraction of the catalyst and co-catalyst are separated after the reaction and recycled. In a preferred application, the olefin is ethene, and the haloalkane product is 1,1,1,3-tetrachloropropane. Two distillation steps take place in order to enhance the production of 1,1,1,3-tetrachloropropane.

Abstract: Isopropyl chloride (IPC) is prepared by the chlorination of propane or propene or propyne, or by any other means resulting in an IPC product containing significant amounts of undesired olefins. Such impure product may be purified by chlorination followed by distillation, by distillation followed by chlorination followed by distillation, by chlorination followed by treatment to reduce chlorine concentration followed by distillation, or by distillation followed by chlorination followed by treatment followed by distillation.
