Abstract:
The present invention relates to methods by which the thermal dissociation of Michael adducts present in a stream of crude acrylic acid, called “crude ester grade”, and the esterification reaction of acrylic acid present in the stream of crude acrylic acid, or generated in situ by thermal dissociation, with a light alcohol, are carried out simultaneously.
