20150025282 | Process to make 1,1,2,3-Tetrachloropropene - Disclosed is a process for the synthesis of 1,1,2,3-tetrachloropropene (HCC-1230xa) using 1,1,3-trichloropropene (HCC-1240za) and/or 3,3,3-trichloropropene (HCC-1240zf) and Cl | 01-22-2015 |
20150274616 | Method to Produce 1,1,2,3-Tetrachloropropene with High Yield - The present invention provides a method for the high yield production of HCC-1230xa from the known four step method, wherein the Step 3 crude product (crude HCC-240db) is used directly as the starting material in the Step 4 reaction—but only if the crude HCC-240db contains less than 0.5 wt % of impurities selected from the group consisting of HCC-250fb, HCC-1240za, and mixtures thereof. | 10-01-2015 |
20160096786 | Method to Improve Halogenation Reactions - In the halogenation reaction of olefin/halo-olefin (i.e., organic), an excess amount of halogen gas (fluorine, chlorine, vaporized bromine and iodine, or their combination) is normally used in order to achieve as complete as possible conversion of the organic. In a conventional process, the excess halogen gas in the off-gas stream is scrubbed by caustic solution which increases the consumption of halogen and generates waste for disposal. The present invention provides a novel process to recover and reuse the excess halogen gas and thus reduce the operating cost of the process. | 04-07-2016 |
