Abstract:
The invention pertains to a method for converting butanediol into butadiene that is fed with a butanediol feedstock, where said method comprises at least an esterification step, a pyrolysis step, and a step for separation of the pyrolysis effluent comprising at least one section for cooling said pyrolysis effluent and producing a liquid pyrolysis effluent and a steam pyrolysis effluent and a gas-liquid washing section that is fed at the top with a fraction of the butanediol diester effluent obtained from the esterification step and at the bottom with the steam pyrolysis effluent, where said section produces a butadiene effluent at the top and a washing effluent at the bottom.

Claim (Index 3):
Method in accordance with  claim 1  in which said reaction section of said step a) is implemented in a reactive distillation column in which the butanediol feedstock is introduced into the top part of the column and the carboxylic acid is introduced into the bottom part of the column, with the ratio of the molar flow rates of butanediol and carboxylic acid being between 2 and 6.
