The present invention provides a novel production process for {HEAD ~ a hydroxyalkyl acrylate}, in which it is possible that: in a batch reaction system, the amount of the hydroxyalkyl acrylate as produced is kept nearly on the same level as conventional and further, at the same time, there is suppressed the side production of {TAIL ~ the alkylene} oxides diaddition product (dialkylene glycol monoacrylate) that lowers the purity of the product to thus give a bad influence upon its quality
