Abstract (en)
[origin: CN101337889A] The present invention relate to a method for preparing (methyl) acrylate, which comprises an ester exchange reaction of alcohol and (methyl) acrylate with low boiling point when a catalyst exists, wherein the alcohol discharged by the (methyl) acrylate with low boiling point is separated. The invention is characterized in that the molar ratio between the (methyl) acrylate with low boiling point and the alcohol as the raw material is increased through adding the (methyl) acrylate with low boiling point. The method of the invention makes that the (methyl) acrylate with extraordinary high purity can be prepared with an extraordinary low cost.
