    Abstract: Disclosed is a process for the manufacture of haloalkane compounds, and more particularly, to an improved process for the manufacture of the compound 1,1,1,3,3-pentachloropropane (HCC-240fa), which mitigates the formation of by-products. The present invention is also useful in the manufacture of other haloalkane compounds such as HCC-250 and HCC-360. One embodiment of the process comprises a method and system for avoiding the formation of polyvinyl chloride during the production of HCC-240fa from CCl4, in which vinyl chloride (VCM) is fed into a reactor as a vapor instead of as a liquid, using a diffusing device to further increase the contact surface between VCM vapor and CCl4.

    Abstract: Disclosed is a process for the manufacture of haloalkane compounds, and more particularly, an improved process for the manufacture of the compound 1,1,1,3,3-penta-chloropropane (HCC-240fa), which mitigates the formation of by-products from vinyl chloride (CH2=CHCl). The present invention is also useful in the manufacture of other haloalkane compounds such as HCC-250 and HCC-360. One embodiment of the invention comprises a method for mitigating 1,1,3,3,5,5-hexachloropentane and 1,1,1,3,5,5-hexachloropentane formation in the HCC-240fa manufacturing process, in which FeCl3, is introduced to a reactor only after the start-up phase has ended and a continuous operation has started. In a preferred embodiment, "pre-chelated" FeCl3, which is concentrated in a catalyst recovery column, is introduced to reactor after the continuous operation has started.

    Abstract: Disclosed is a method for capturing and recycling iron catalyst used in the production of haloalkane compounds and more particularly, to an improved process for the manufacture of the compound 1,1,1,3,3-pentachloropropane (HCC-240fa), in which an electromagnetic separation unit (EMSU) is used to facilitate the reaction. When energized, the EMSU functions to remove all iron particles from the reactor effluent; when de-energized, the iron particles captured by the EMSU can be flushed back into the reactor for re-use in the continued production of HCC-240fa. The present invention is also useful in the manufacturing processes for other haloalkane compounds such as HCC-250 and HCC-360.
