Abstract
A process for producing carbon tetrachloride comprising reacting i) chlorine, ii) a C1 chlorinated compound comprising 1 to 3 chlorine atoms, and iii) a carbon/second chlorine source, wherein the second chlorine source comprises a range of multichlorinated C3 hydrocarbons, said range being obtained as waste products from the industrial production of 1,1,1,2,3-pentachloropropane and/or 1,1,3,3-tetrachloropropene.
Claims10
A process for re-utilization of carbon and chlorine in the preparation of carbon tetrachloride comprising reacting a) chlorine, b) chloroform, methyl chloride, and/or methylene chloride, and c) a carbon/second chlorine source selected from i) at least one of methane, ethane, ethene, propane, propene, dichloroethane, and dichloropropane and ii) a range of multichlorinated C3 hydrocarbons, said range being obtained by recycling waste products from industrial production of 1,1,1,2,3-pentachloropropane and/or 1,1,3,3-tetrachloropropene.
