In view of its low octane number (25), hexane is an undesirable constituent of synthetic gasoline. Hexane is present in considerable quantities in straight-run gasoline and in the cracking distillates of petroleum. Under the conditions of petroleum product aromatization and catalytic reforming, hexane is dehydrocyclized to benzene. The hexane isomers 2,2-dimethylbutane and 2,3-dimethylbutane (diisopropyl) are additives improving the quality of motor fuels.
