IMPROVED LIQUID ACID ALKYLATION CATALYST AND ISOPARAFFIN:OLEFIN ALKYLATION PROCESS

摘要

The invention provides an isoparaffin:olefin alkylation catalyst composition comprising from about 10 to about 90 weight percent of at least one selected from the group consisting of hydrofluoric acid and the halogenated sulfonic acids together with from about 10 to about 90 weight percent of a solvent having a donor number of less than about 40 in the absence of intentionally added metal halide. An isoparaffin:olefin alkylation process employing the catalyst composition of the invention is also disclosed.
