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.
