ABSTRACT:
There is disclosed a novel production process for a hydroxyalkyl (meth)acrylate in which: the diffusion of harmful substances due to disposal of catalysts can be reduced; and also the amount of the catalyst as used can be greatly saved in the entire production process. This production process comprises the step of carrying out a reaction between (meth)acrylic acid and an alkylene oxide in the presence of a catalyst in order to produce the hydroxyalkyl (meth)acrylate; with the production process being characterized by further comprising the step of recovering the catalyst as has been used for the reaction.
