Abstract
Disclosed is a method for producing a hydroxyalkyl (meth)acrylate having high production efficiency and placing little burden on a production system. The method for producing a hydroxyalkyl (meth)acrylate comprises a reaction step of reacting (meth)acrylic acid with an alkylene oxide in a reactor while stirring a liquid containing (meth)acrylic acid and the alkylene oxide with a stirrer to obtain a reaction liquid containing a hydroxyalkyl (meth)acrylate, and thereafter a deaeration step of reducing a pressure in the reactor while stirring the reaction liquid with the stirrer to vaporize and remove an unreacted alkylene oxide in the reaction liquid, a number of stirring revolutions of the stirrer in the deaeration step being reduced to 30 to 85% of a number of stirring revolutions of the stirrer in the reaction step.
