摘要

The invention relates to a process for producing butadiene from an ethanol feedstock, comprising a step of converting the ethanol into butadiene, a distillation step, a step of washing with water, a butadiene purification step comprising at least one section for separating the 1-butene by extractive distillation and a final distillation section fed with the topped butadiene distillate, separating at the top a purified butadiene effluent and at the bottom a butene residue, and an effluent treatment step.
