摘要:
The present invention relates to processes for preparing alkyl (meth)acrylates, comprising the steps of transesterifying an alkyl α-hydroxycarboxylate with (meth)acrylic acid to obtain alkyl (meth)acrylates and α-hydroxycarboxylic acid, and dehydrating the α-hydroxycarboxylic acid to obtain (meth)acrylic acid.
