Abstract:
The invention relates to a method for producing 1,3-butanediene from a butanediol feedstock that includes: a) A step for esterification of butanediol by a carboxylic acid to form the corresponding diester; b) A step for pyrolysis of the diester effluent obtained from step a); c) A step for distillation fed by at least the carboxylic acid effluent obtained from step a), and producing an aqueous distillate and a carboxylic acid residue; d) A step for drying the carboxylic acid that is fed at least by the carboxylic acid residue obtained from step c) and producing a water effluent and a carboxylic acid product that feeds step a).

Claim (Index 6):
Method according to  claim 1 , in which the dwell time in said reactive distillation column of step a), defined as the volume of the reactive distillation divided by the volumetric flow rate of said diol feedstock and said carboxylic acid feedstock, is between 0.5 h and 10 h.
