Abstract:
A process can be used for producing a distillate product with a methanol concentration greater than the concentration of methanol in the minimum boiling azeotrope of methanol and methyl (meth)acrylate, from a mixture with a methanol concentration less than the concentration of methanol in the minimum boiling azeotrope of methanol and methyl (meth)acrylate, in a distillation column. A transesterification process for preparing C6- to C22-alkyl, aryl or alkenyl (meth)acrylates from methyl (meth)acrylate is also provided.
