A process of the type for producing 1,1,1,2,3-pentachloropropane by introducing 1,1,1,3-tetrachloropropane, chlorine, and Lewis acid catalyst, optionally in the presence of carbon tetrachloride, the improvement comprising introducing the Lewis acid as a slurry within a chlorinated hydrocarbon.

Process for the production of chlorinated hydrocarbons

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

In an oxychlorination process of the type where ethylene is converted to 1,2-dichloroethane in the presence of a supported copper catalyst, the improvement comprising: the use of a supported catalyst prepared by (i) impregnating, within a first step, an alumina support with a first aqueous solution including copper, to thereby form a first catalyst component; and (ii) impregnating, within a subsequent step, the first catalyst component with a second aqueous solution including copper and alkaline earth metal, to thereby form the supported catalyst.

Catalyst and process for oxychlorination of ethylene to dichloroethane

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

In an oxychlorination process of the type where ethylene is converted to 1,2-dichloroethane in the presence of a supported copper catalyst, the improvement comprising: the use of a supported catalyst prepared by (i) impregnating, within a first step, an alumina support with a first aqueous solution including copper, an alkaline earth metal, and an alkali metal to thereby form a first catalyst component; and (ii) impregnating, within a subsequent step, the first catalyst component with a second aqueous solution including copper and alkaline earth metal, where the second aqueous solution is substantially devoid of alkali metal, to thereby form the supported catalyst.

A process of the type for producing chlorinated propanes by reacting carbon tetrachloride with ethylene within a tank reactor that includes a liquid reaction mixture and a headspace above the reaction mixture wherein ethylene gas diffuses from the liquid reaction mixture into the headspace while agitating the reaction mixture, the improvement comprising transferring ethylene within the headspace back into the reaction mixture through a conduit within the mixing device that agitates the reaction mixture.

Methods for producing halogenated propanes

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.
