Abstract

Catalytic disproportionation of gutene-2 and/or penten-2 with isobutene and/or a vinyl aromatic-type compd. using a catalyst consisting of at least 75 wt. % Al2O3 carrier, 7.0-9.0 (esp. 7.8-9.2) wt. % tungsten cpds. (as W) and alkali metal cpds. with an alkaline reaction, and having an atomic ratio alkali metal: W of 0.2-0.5 (esp. 0.3-0.4). Process is pref. carried out at 150-300 degrees C (esp. 210-240 degrees C) and 0.9-20 atm. abs., using 1-150 litres alkenes (as liquid) per litre catalyst. Disproportionation of isobutene with butene-2 gives propylene and 2-methylbutene-2 which can be dehydrogenated to isoprene. Styrene or alpha-methyl styrene disproportionated with butene-2 gives 1-phenylpropene-1 and 2-phenylbutene-2 respectively. Catalyst gives high yields and good selectivity with reduced by-product formation. Catalyst is made by impregnating the carrier with solutions of the tungsten and alklia metal (esp. potassium) compounds followed by drying and heat treating for 1-10 hrs. at 300-350 degrees C.
