Abstract
An improved process for converting 3,3-dichloropropene in an intermediate boiling byproduct stream from a process of making allyl chloride by the chlorination of propylene to cis- or trans-1,3-dichloropropene or a mixture of these, wherein the intermediate boiling byproduct stream is processed batchwise or continuously to dry the stream to a water content of less than about 15 parts per million by weight, and then is contacted in the liquid phase with an alumina, silica or zeolite catalyst under conditions effective to carry out the conversion.
