Abstract

Obtaining of individual 1-butene and 2-butenes from the butane-butene fractions can be processed sufficiently effectively by combining positional isomerization of alkenes on the sulfocation exchanger catalysts and careful rectification. At 50–60°C is reached the equilibrium with the ratio of the sum of 2-butenes to 1-butene ∼20:1. The relatively high-boiling 2-butenes are enough completely separated by rectification of 1-butene, and isobutane from the harmful impurities (butadiene and isobutene). The reverse isomerization of the purified 2-butene into 1-butene with the continuous distillation of the latter makes it possible to obtain pure 1-butene with a very low prime cost.
