Claims3
An alkylation process which comprises contacting an alkylatable paraffinic hydrocarbon and an olefinic alkylating agent at alkylation conditions with a catalyst composition comprising a strong acid in the presence of a promoter, the promoter comprising from 5-85% by weight of an oil-soluble C.sub.8 -C.sub.24 tertiary alkyl primary amine salt of a mixed C.sub.6 -C.sub.22 mono- and di-alkyl phosphate ester, from 5-55% by weight of either alpha or beta pinene and with the balance of said promoter being a hydrocarbon solvent.
