Abstract

Isobutylene is selectively polymerised in the presence of unbranched butylenes with a heteropoly acid catalyst at 20-200 DEG C. for a time sufficient to convert at least 75% of the isobutylene and insufficient to convert more than 10% of the unbranched butylenes. Liquid phase operation is preferred using a supported catalyst at a space velocity of 1-40 vol./vol./hr. and any convenient pressure, e.g. 1-100 atmospheres. Specified catalysts are phospho-tungstic, phosphomolybdic, phospho-molybdic-tungstic, phosphovanadic, silico-tungstic, silico-molybdic, arsenomolybdic and boro-tungstic acids supported on silica gel, alumina, silica-alumina, aluminium silicate or pumice preferably containing at least 50% by weight of free or combined silica and having an alkali content (including ammonium), below 1 milli-equivalent per 100 grams, the acid forming 0,5-50% by weight of the composition. Dimers and trimers are formed, the dimer being principally iso-octane after hydrogenation, the trimer being a mixture of 2,2,6,6,-tetramethyl-4-methylene-heptane and 2,2,4,6,6,-pentamethyl-3-heptene which after hydrogenation yield 2,2,4, 6,6-pentamethyl-heptane. Butylene-1 is simultaneously isomerised to butylene-2 as described in Specification 847,066.
