Abstract

1475191 Isomerizing 2,3-dimethyl-1-butene GOODYEAR TIRE & RUBBER CO 11 Oct 1974 [12 Nov 1973 (2)] 44177/74 Heading C5E 2,3-Dimethyl-2-butene is prepared by isomerizing 2,3-dimethyl-1-butene in the liquid phase at 5-80‹ C. and at LHSV of 0À5-40 in the presence of a catalyst comprising a macroreticular sulphonated ion-exchange resin. Preferably the isomerization is carried out in the presence of 0À05-1 wt. per cent water or substance, e.g. an alcohol, which will release said amount of water at isomerization conditions. The macroreticular resin may be prepared by the copolymerization of styrene and divinylbenzene in the presence of an inert material, followed by removal of the inert material and subsequent sulphonation of the polymer.
