Abstract
A process for recovery of the light noble products present in the distillation residues from the process for the manufacture of acrylic acid and of its esters and C1-C8 alcohols, which comprises thermal cracking of the residues and the noble products which consist of acrylic acid monomers, acrylate monomers and alcohols, which is characterized in that the thermal cracking is performed in the absence of a catalyst on a mixture of heavy distillation residues originating, on the one hand, from the manufacture of acrylic acid and, on the other hand, from the manufacture of the esters; the light fraction originating from the dissociation reactions is continuously vaporized during the cracking operation and this light fraction is distilled in order to recover, after condensation, the required products.
