ABSTRACT:
The present invention relates to a novel alkylation catalyst complex and to alkylation processes employing such a catalyst complex. More specifically, the invention relates to a novel catalyst complex comprising a BF.sub.3 :H.sub.3 PO.sub.4 adduct, and at least one polar hydrocarbon formed in situ. The catalyst complex may optionally include water as well as an added solubilizing agent. The invention further includes a pretreatment method for enhancing the isoparaffin selectivity of a catalyst complex containing a BF.sub.3 :H.sub.3 PO.sub.4 adduct.
