To the mechanism of the isobutane alkylation with butenes

Abstract

The arguments in favor of a change in the accents at the description of the reaction mechanism of the isobutene alkylation with butylenes in the presence of sulfuric acid are proposed. The reaction of sulfate sulfur reduction that until now considered as the side process is proposed to suggest as just the initiation of chain process which includes generation of tert-butyl cations. Such a concept makes it possible to explain a number of characteristic experimental data, in particular failure of attempts of creation of the effective solid catalyst for the alkylation on the basis of the sulfated zirconium oxides.
