Abstract: The present invention relates to a process for the production of 1, 3 -butadiene which comprises the following phases : a) extracting, by means of extractive distillation, in an extraction section, an end-product containing 1, 3 -butadiene and a raffinate product, starting from mixtures of saturated and unsaturated compounds having from 2 to 10 carbon atoms in the chain; b) sending the raffinate product to a dehydrogenation section; c) dehydrogenating the raffinate product in the dehydrogenation section in the presence of a dehydrogenation catalyst and an inert product so as to form a reaction effluent containing 1,3- butadiene; d) recirculating the reaction effluent containing 1, 3 -butadiene directly to the extraction section after separating the incondensable compounds.
