A method of producing carbon tetrachloride includes providing a chloromethanes stream, combining the chloromethanes stream with chlorine and additional carbon tetrachloride to form a reaction mixture, wherein the reaction mixture includes at least stoichiometric levels of chlorine, introducing electromagnetic radiation to the reaction mixture and subjecting the reaction mixture to suitable reaction conditions to form product carbon tetrachloride, and collecting a product stream including the product carbon tetrachloride.

Photochlorination of partially-chlorinated chloromethanes to carbon tetrachloride

A method of producing carbon tetrachloride, the method comprising the step of reacting chlorine with chloroform in the presence of electromagnetic radiation within a reaction mixture that includes the chlorine, the chloroform, and carbon tetrachloride, where the concentration of chloroform is less than 5000 ppm by weight relative to the weight of the reaction mixture, where the reaction mixture includes at least stoichiometric levels of chlorine relative to chloroform, where the electromagnetic radiation creates chloride radicals, and where the reaction mixture is well mixed.

Photochlorination of chloroform to carbon tetrachloride

A process for the manufacture of 1,1,3,3-tetrachloropropene, the process comprising dehydrochlorinating 1,1,1,3,3-pentachloropropane, where said step of dehydrochlorinating 1,1,1,3,3-pentachloropropane takes place in the presence of an oxidizing agent and in the presence of a Lewis acid, and where the oxidizing agent is chlorine and the Lewis acid is ferric chloride.

Method for making 1,1,3,3-tetrachloropropene

A method for providing particles of polyvinyl chloride, wherein the particles offer improved chlorinating efficiency, the method comprising (i) providing polyvinyl chloride particles; and (ii) introducing a chlorination accelerant to the polyvinyl chloride particles to thereby provide polyvinyl chloride particles having an accelerant associated therewith.

Methods for providing polyvinyl chloride particles for preparing chlorinated polyvinyl chloride

A process for the manufacture of 1,1,3,3-tetrachloropropene, the process comprising dehydrochlorinating 1,1,1,3,3-pentachloropropane.

Methods for the manufacture of 1,1,1,2,3-pentachloropropane from 1,1,1,3-tetrachloropropane and chlorine are disclosed. Improved methods are provided for the manufacture of 1,1,2,3-tetrachloropropene from 1,1,1,2,3-pentachloropropane. Methods are also disclosed for the manufacture of 1,1,2,3-tetrachloropropene from 1,1,1,3-tetrachloropropane and chlorine and for the manufacture of 1,1,2,3-tetrachloropropene from carbon tetrachloride, ethylene, and chlorine.

Methods of making chlorinated hydrocarbons

A method for chlorinating polyvinyl chloride, the method comprising providing polyvinyl chloride particles having a chlorination accelerant associated therewith, where the particles are suspended in water; and chlorinating the polyvinyl chloride particles having a chlorination accelerant associated therewith.

Methods for chlorinating polyvinyl chloride

Processes for isolating 1,1,1,2,3-pentachloropropane from a crude product stream containing the 1,1,1,2,3-pentachloropropane and ferric chloride. The processes may include deep distillation of the crude, treatment of the crude with a reagent that deactivates the ferric chloride followed by distillation on the deactivated crude stream, aqueous washing of the crude product stream to remove ferric chloride followed by distillation on the deactivated crude stream. Other embodiments simultaneously prepare 1,1,2,3-tetrachloroprene and 1,1,1,2,3-pentachloroprane.
