Abstract

Medium-chain olefins containing as impurities 2-alkyl substituted isomers having a close boiling point are purified by (i) passing over a solid acid catalyst under mild conditions to selectively double-bond isomerise said impurities, and (ii) separating said isomerised olefins by distillation.
