Abstract
Trifluoromethanesulfonic acid (TFSA) catalyzed isobutane-isobutylene a lkylation modified with trifluoroacetic acid (TFA) or water, was studi ed over a wide range of acidity (Ho: - 10.1 to - 14.1). The effect of the acidity of these nonoxidizing strong mixed acid systems on the alk ylation, is reported. For both systems, the best alkylation conditions were those at an acid strength of about Ho = - 10.7, giving a calcula ted research octane number (RON) of 89.1 (TFSA/TFA) and 91.3 (TFSA/H2O ).
