Abstract:
The invention relates to a process for producing butadiene from an ethanol feedstock comprising a step of converting ethanol into butadiene, a step of separating the reactants into a hydrated butadiene effluent, an impurities effluent and an ethanol-butadiene effluent, a separation step that separates the ethanol-butadiene effluent into a butadiene distillate and a contaminated reactants effluent, a step of purifying the butadiene by extractive distillation and an effluent treatment step.
