Abstract
A process is disclosed for alkylating an isoparaffin with an olefin using HF acid. Unreacted isoparaffin, usually isobutane, is recycled. The presence of a free HF acid phase in isobutane recycled to the reaction zone can be tolerated because the deleterious effects of the HF acid are attenuated by the addition of an organic diluent. A preferred source of organic diluent is the bottoms fraction from the HF acid regenerator.
