Abstract
The present disclosure is directed to upgrading to commercially useful products heavy ends by-products formed during the manufacture of allyl chloride. These heavy ends by-products are upgraded by first reacting the by-products with an alcohol in the presence of a base and subsequently pyrolyzing the resultant ethers to produce a mixture of allyl chloride and a carbonyl compound. This process improves the overall yield of the allyl chloride and forms commercially useful carbonyl compounds.
