PROCESS FOR THE PRODUCTION OF CHLORINATED PROPENES
-
Paragraph 0069; 0070; 0071, (2014/07/08)
Processes for the production of chlorinated propenes are provided. The processes make use of 1,2-dichloropropane as a starting material and subject a feedstream comprising the same to an ionic chlorination process. At least a portion of any tri- and tetrachlorinated propanes not amenable to ionic chlorination conditions are removed from the ionic chlorination product stream, or, are subjected to chemical base dehydrochlorination step. In this way, recycle of intermediates not amenable to ionic chlorination reactions is reduced or avoided, as is the buildup of these intermediates within the process. Selectivity and, in some embodiments, yield of the process is thus enhanced.
PROCESS FOR THE PRODUCTION OF CHLORINATED ALKANES
-
Paragraph 0034; 0035, (2013/06/27)
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.
PROCESS FOR THE PRODUCTION OF CHLORINATED ALKANES
-
Paragraph 0047; 0048, (2013/06/27)
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.

, p. 1372 - 1376 (2007/10/02)
The purpose of this investigation is to determine the kinetic characteristics of this process, which are to form the basis of a model of the chlorination reactor. It is found that the activation energy E equals 43. 22 plus or minus 1. 78 kJ/mole for the reaction of substitutional chlorination of TCP in presence of DCP is considerably lower than the activation energy of thermal chlorination (83. 7-104. 7 kJ/mole), confirming the existence of an inductive effect in additive chlorination in a system of concurrent reactions I and II.
