PREPARATION OF 2-HALO-1-ALKENES AND ACRYLATE ESTERS FROM HYDROCARBONS STREAMS

摘要

A 2-halo-1-alkene (such as 2-chloro-1-pro-pene) is prepared by contacting together, in the presence of a catalyst (such as alumina), (a) a 1,2-diene (such as propadiene) and/or a 1-alkyne (such as propyne), with (b) a hydrogen halide (such as HCl); in the presence of at least 1,000 ppm water. The process of the invention provides unexpected selectivity for the desired product. 28,803A-F -18-
