        Isobutylene, obtained by dehydrogenation of BuOH produced in the synthesis of MeOH from water gas, mixed with a small amount of gaseous HCl, is heated to 100°-250° and passed over solid Al₂O₃ previously activated by heating to 400°-450°.  The isooctene produced is then hydrogenated to isooctane.
