摘要： For obtaining butene-1 from butene-2, a charge containing at least one of the isomers of butene-2 is introduced into a distillation zone linked to a hydro-isomerization zone. Part of the effluent from the bottom of the distillation column is removed from the distillation zone, heated in a heat exchanger and passed into an external hydro-isomerization zone. The hydro-isomerization effluent is removed from the hydro-isomerization zone, cooled in a heat exchanger, and then reintroduced into the distillation zone. Effluent containing butene-1 is withdrawn from the top of the column of the distillation zone.
