Method for capturing and recycling the iron catalyst was used in the preparation of haloalkane compound

How the iron catalyst was captured recirculated used in the preparation of haloalkane compound, and more particularly, to promote the reaction by using the electromagnetic separation unit (EMSU), the compound 1,1,1,3,3-pentachloropropane ( It discloses an improved method for the production of HCC-240fa). EMSU functions to retrieve the iron particles from the reactor effluent stream and a voltage is applied, when the voltage is released, the iron particles captured by EMSU, reactor for reuse in the continuous production of HCC-240fa it can be returned by flow into. The present invention is also useful in the manufacturing process of other haloalkane compounds such as HCC-250 and HCC-360. .FIELD 1
