摘要:
The present invention relates to the production of bio-based acrolein and acrylic acid using glycerol as a raw material and, more specifically, relates to a method for manufacturing acrolein and acrylic acid according to which a reaction is performed to dehydrate glycerol into acrolein and eliminate the heavier-than-water organic compounds that can be found in the various flows of the method, such as to obtain a flow that can be recycled in the dehydration step with no build-up of heavy impurities, while minimising water consumption and the emission of polluted aqueous flows.
