Abstract

Butadiene (I) was sepd. from a petroleum cracking fraction contg. butanes, butenes, isobutylene (II) and acetylenes by etherification of II with alcohol in the presence of an acidic ion exchange resin at 20-80≰C, etherification of acetylenes with alcohol in the presence of a Hg-contg. acidic ion exchange resin at 20-80≰C, and fractionating the products to give I, purity >= 99.5%, acetylene content < 50 ppm.
