Abstract
A process for producing an alkylation reaction product from an isoparaffin and an olefinic reactant containing 1-butene, 2-butene and isobutylene by fractionating the olefinic reactant into a 2-butene fraction and a separate 1-butene and isobutylene fraction. The 2-butene is charged to an HF alkylation reaction zone with isobutane. The mixture is heated by the endothermic reaction, and the fraction comprising 1-butene and isobutylene is then added to the unitary reaction zone. It is possible to alkylate these olefins at conditions which are close to the optimum conditions, using a single reactor vessel, which operates at different temperatures without the necessity for heat exchange means.
