Abstract:
The present invention provides improved processes for preparing halogenated alkanes. In particular, the processes comprise reacting an alkene, a halogenated alkene, or combinations thereof and a halogenated methane with at least one chlorine atom.

Claim (Index 1):
A process for producing halogenated alkanes, the process comprising:\n a. forming a reaction mixture in a reactor by contacting: a liquid phase comprising a halogenated methane comprising at least one chlorine atom, at least one phosphorus containing compound comprising a trialkylphosphate, a trialkylphosphite, or combinations thereof; and at least one catalyst comprising a metal, metal salt, or combinations thereof; an alkene, halogenated alkene, or combinations thereof, thereby forming a reaction mixture; wherein the alkene, halogenated alkene, or combinations thereof and is at least partially absorbed into the liquid phase; b. stirring the reaction mixture; c. heating the reaction mixture; and d. producing halogenated alkanes and heavy by-products; wherein there is a gas phase above the reaction mixture and when the order of steps b. and c. may be switched or conducted at the same time; wherein the process further comprises at least one of the following:\n (I) stirring the reaction mixture comprises jet mixing; and \n (II) the process further comprises step e., wherein step e. comprises: \n i. transferring at least part of the reactor contents into a first separator where two product streams (a) and (b) are formed: wherein product stream (a) comprises the halogenated alkane, halogenated methane comprising at least one chlorine atom, and an alkene or halogenated alkene; wherein product stream (b) comprises the heavy by-products, the at least one phosphorous containing compound, and at least one catalyst; \n ii. contacting at least a portion of product stream (b) with an ion exchange resin to form product stream (c) wherein product stream (c) contains less of at least one metal ion when compared to product stream (b); and \n iii. returning at least a portion of product stream (c) to the reactor; and \n (III) the process further comprises step f, wherein step f comprises: \n i. transferring at least part of the reactor contents into a first separator where two product streams (a) and (b) are formed, wherein product stream (a) comprises the halogenated alkane, halogenated methane with at least one chlorine atom, and the alkene, halogenated alkene, or combinations thereof and product stream (b) comprises the heavy by-products, the at least one phosphorous containing compound, and the at least one catalyst; \n ii. transferring at least a portion of product stream (b) back into the reactor; \n iii. transferring product stream (a) into a second separator and producing two product streams (d) and (e), wherein product stream (d) comprises the halogenated alkane and product stream (e) comprises halogenated methane with at least one chlorine atom and the alkene, halogenated alkene, or combinations thereof; \n iv. optionally introducing at least a portion of product stream (e) into the reactor;\n wherein at least one of the first separator and the second separator comprises a reboiler, bottom stage, or both; \n wherein the first separator or the second separator may be separate or contained in a single separation device; \n wherein when the first and second separation devices are contained in a single separation device, the single separation device will separate at least a portion of product stream (d) from product streams (b) and (e); and \n wherein one or more of the separators is a multistage distillation column in which a gas or low boiling liquid comprising alkane, alkene, halogenated alkane, halogenated alkene, or nitrogen is introduced into first separator reboiler, second separator reboiler, first separator bottom stage, second separator bottom stage, or combinations thereof.
