Abstract
This invention relates to a process for the continuous production of a (meth)acrylic ester by transesterification reaction between a C1-C4 light alkyl (meth)acrylate, with a heavy alcohol in the presence of a catalyst, characterised in that the flows feeding the reactor are introduced through a static mixer placed on a recirculation loop of the reactor. The use of a static mixer improves the selectivity of the reaction and consequently the overall productivity of (meth)acrylic ester synthesis process.
