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.

Preparation of acid chlorides

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.

Purification of recycled paraffins in photochlorination process

The compound p-phenoxybenzotrichloride, useful as an intermediate in the preparation of various pesticides and monomers for the production of polyketone polymers, is prepared by the light-catalyzed reaction of p-phenoxytoluene with chlorine.
