    摘要: A process is described for obtaining high-purity 1-butene starting from C
    4 hydrocarbon mixtures containing isobutene, n-butane, isobutane, 1, 3 -butadiene, 1-butene, 2- butenes and also optionally C
    3 and C
    5 hydrocarbons, comprising the following stages: conversion of isobutene effected in a double stage, wherein each stage consists of one or more reactors followed by a distillation column for the recovery of the reaction product; recovery of the excess alcohol; recovery of 1-butene using at least two distillation columns; characterised in that it also uses a further conversion stage, consisting of one or more reactors in series, for completing the isobutene removal.

    摘要: Vinylidene olefin is removed from an olefin mixture containing 1 to 55 mole percent vinylidene olefin, 0 to 10 mole percent internal olefin, and the balance vinyl olefin, by:

    (A) reacting the olefin mixture in the presence of a BF₃-water and/or active proton-containing organic promoter catalyst system so as to selectively dimerize said vinylidene olefin, and
    (B) separating said vinyl olefin and internal olefin from the dimerized vinylidene olefin to produce an olefin product having a reduced vinylidene olefin content compared to said olefin mixture.
