ABSTRACT:
The invention provides a catalyst complex for promoting alkylation of an isoparaffin with an olefin, said catalyst complex comprising the reaction product of BF.sub.3 and at least one selected from the group consisting of H.sub.3 PO.sub.4 and H.sub.2 O; and, additionally, excess BF.sub.3 in concentration of from about 10 ppm (weight) to about 5 percent by weight of the total isoparaffin and olefin feed.
The invention further provides a process for the alkylation of an isoparaffin with an olefin by contacting a mixture of isoparaffin and olefin with the catalyst complex of the invention, decanting the hydrocarbon product from the catalyst complex, and deacidifying the hydrocarbon product.
