A promoter composition useful in a strong acid catalyzed alkylation process, the promoter comprising from 5-8% by weight of an oil-soluble C.sub.8 -C.sub.24 tertiary alkyl primary amine salt of a mixed C.sub.8 -C.sub.22 mono- and di-alkyl phosphate ester, from 5-55% by weight of either alpha or beta primene and with the balance of said promoter being a hydrocarbon solvent.
An organic salt comprising the 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.
