Filed:

Nov 7, 1997

Appl. No.:

8/965817

Inventors:

James G. Colson - Williamsville NY
Ramesh Krishnamurti - Williamsville NY
Rose Adinolfe - Newfane NY

Assignee:

Occidental Chemical Corporation - Niagara Falls NY

International Classification:

C07C 5158

US Classification:

562863

Abstract:

Disclosed is a method of making an acid chloride having the general formula ##STR1## where each R contains no unsaturated groups and is preferably independently selected from aliphatic from C. sub. 1 to C. sub. 7 and aryl from C. sub. 6 to C. sub. 15. A solution is formed in an inert solvent of an aldehyde having the general formula ##STR2## and chlorine gas is sparged into said solution. The reaction between the aldehyde and the chlorine gas to produce the acid chloride is performed in the absence of a catalyst, an initiator, and ultraviolet light. A chlorinated acid chloride can be prepared from the acid chloride by reacting it with additional chlorine in the presence of a chlorine free radical generator.

US Classification:

204163R

Abstract:

An improved process for the photochlorination of normal paraffins to prepare mono-chlorinated alkanes, in which the normal paraffin feed stream is only partially chlorinated and the unreacted normal paraffins separated and recycled, the recycled unreacted paraffin being treated with a basic material capable of removing polar impurities therefrom which may hinder the photochlorination reaction.
