1-Butene of high purity is prepd. by treating a C4 olefin fraction with MeOH to convert isobutene to Me3COMe and distg. the product to give a mixt. of isobutane, butane, and 1- and 2-butenes which are hydrogenated to eliminate butadiene, freed of isobutane, and fractionated. Thus, a mixt. of isobutene 1.3, butane 6.4, 1-butene 27.9, 2-butenes 14.5, isobutene 49.6, and butadiene 0.3% is treated with MeOH at 50-90≦̸C in the presence of amberlyst 15, and the product is distd. to remove MeOH and Me3COMe, giving a fraction (contg. 0.1% isobutene and 1.3% isobutane) which is hydrogenated, freed of isobutane, and fractionated to give 1-butene.
