摘要
The invention relates to a method for the production of butadiene from an ethanol feedstock containing at least 80 wt. % ethanol comprising: a step of converting the ethanol into acetaldehyde a step of extracting the butadiene a step of washing the gaseous by products with water a step of eliminating impurities and brown oils a step of treating the effluent a first step of purifying the butadiene and a subsequent step of purifying the butadiene said ethanol feedstock supplying the butadiene extraction step and the organisation of the steps and recycling allowing recycling to be maximised and water and energy consumption to be minimised.
