Abstract (en)

[origin: WO2017153653A1] The present invention relates to a method for synthesising C1 -C10 alkyl (meth)acrylates, by direct esterification of (meth)acrylic acid with the corresponding alcohol, wherein the reaction is carried out in a fixed-bed membrane reactor under conditions where the water generated by the reaction is eliminated from the reaction medium as said water forms. The method according to the invention can operate under conditions for which the reagents are not in excess, thus minimising the size and the energy of the equipment for separating/recycling the streams generated during the purification of the reaction medium.
