Process for producing hydroxyalkyl (meth)acrylate

摘要

The present invention provides a process for producing a hydroxyalkyl (meth)acrylate which comprises the step of carrying out a reaction between (meth)acrylic acid and an alkylene oxide, wherein the process provides enablement for economically and efficiently recovering and recycling the unreacted residue of the alkylene oxide. The process for producing a hydroxyalkyl (meth)acrylate comprises the steps of, carrying out a reaction between (meth)acrylic acid and an alkylene oxide; stripping the unreacted residue of the alkylene oxide from the resultant reaction liquid; and causing a solvent to absorb the stripped alkylene oxide; wherein: water is used as the absorbing solvent; and an absorbing liquid resultant from the absorption of the unreacted residue of the alkylene oxide is used for production of an alkylene glycol.
