20120310020 | METHOD FOR AVOIDING THE GENERATION OF BY-PRODUCTS DURING THE PRODUCTION OF HALOALKANE COMPOUNDS - 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 CC1 | 12-06-2012 |
20120310021 | METHOD FOR MITIGATING THE FORMATION OF BY-PRODUCTS DURING THE PRODUCTION OF HALOALKANE COMPOUNDS - 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 (CH | 12-06-2012 |
20130006025 | PROCESS FOR PRODUCING METHYL CHLORIDE AND SULFUR DIOXIDE - Produce methyl chloride and sulfur dioxide using a reactor with lanthanum oxychloride, and contacting the lanthanum oxychloride with methanesulfonyl chloride under conditions sufficient to convert a portion of the methanesulfonyl chloride to methyl chloride and sulfur dioxide. | 01-03-2013 |
20140323775 | PROCESS FOR THE PRODUCTION OF CHLORINATED ALKANES - Processes for the production of chlorinated alkanes are provided. The present processes comprise catalyzing the addition of at least two chlorine atoms to an alkane and/or alkene with a catalyst system comprising one or more nonmetallic iodides and/or lower than conventional levels of elemental iodine and at least one Lewis acid. The present processes make use of sulfuryl chloride, or chlorine gas, as a chlorinating agent. | 10-30-2014 |
20140323776 | PROCESS FOR THE PRODUCTION OF CHLORINATED ALKANES - Processes for the production of chlorinated alkanes are provided. The present processes comprise catalyzing the chlorination of a feedstream comprising one or more alkanes and/or alkenes with a catalyst system comprising one or more inorganic iodine salts and/or lower than conventional levels of elemental iodine and at least one Lewis acid. The processes are conducted in a nonaqueous media, and so, the one or more inorganic iodine salts are recoverable and/or reusable, in whole or in part. | 10-30-2014 |
20150045592 | PROCESS FOR THE PRODUCTION OF CHLORINATED ALKANES - Processes for the production of chlorinated alkanes are provided. The present processes comprise reacting one or more mono- and/or dichloroalkanes to form tri-, tetra- and/or pentachloroalkanes, with high regioselectivity. In those embodiments wherein a dichloroalkane is desirably utilized, it may advantageously be a vicinal dichloroalkane. Further, only one catalyst is utilized. The present processes make use of sulfuryl chloride as a chlorinating agent, rather than a gaseous chlorinating agent such as chlorine gas. Finally, the process uses lower intensity process conditions than at least some conventional processes, and thus, operating costs are saved. | 02-12-2015 |
