Abstract (en)

[origin: WO2011010036A1] The aim of the invention is to produce a bioresourced acrylic acid from glycerol, that is an acrylic acid essentially based on a carbon source of natural origin, having a degree of purity corresponding to the needs of the users. The method according to the invention comprises a final step of purifying the acrylic acid by fractional crystallisation applied to one of the acrylic acid fractions from the purification chain implemented following the extraction of the acrylic acid obtained from glycerol by counterflow absorption with a hydrophobic heavy solvent.
