Abstract

1,171,950. Separating olefins. IMPERIAL CHEMICAL INDUSTRIES Ltd. 1 Nov., 1968 [29 Nov., 1967], No. 54321/67. Heading C5E. Mixtures of branched and unbranched olefins are separated by selective dimerization of the branched olefin over a catalyst comprising a supported transition metal and/or a compound thereof. Preferred catalysts are oxides or sulphates of nickel or cobalt supported on alumina, silica or magnesia, particularly nickel oxide on silica/alumina. The process is suitably liquidphase, e.g. at 0-150‹ C. In examples the following mixtures are treated, the first-named being selectively dimerized: isobutene and propylene; isobutene and n-butene; and isobutene, nbutene and propylene. Selectivity is enhanced by the presence of minor amounts of polyunsaturated hydrocarbons, e.g. 0.2 wt. per cent of butadiene.
