Abstract:
1. A production process for a hydroxyalkyl (meth)acrylate, which comprises the steps of: a) carrying out a batch reaction in a reactor between an alkylene oxide and (meth)acrylic acid in the presence of a catalyst in order to produce the hydroxyalkyl (meth)acrylate; b) defining a supply time period as a time period during which alkylene oxide and/or (meth)acrylic acid are being supplied into said reactor while content inside said reactor has a temperature of not lower than 40° C.; c) defining a molar ratio time period as a time period during which a molar ratio of alkylene oxide, which has been introduced into said reactor, to (meth)acrylic acid, which has been introduced into said reactor, is more than 1.0; and d) adjusting a supplying of alkylene oxide and/or (meth)acrylic acid into said reactor such that the molar ratio time period is not less than 40% of the supply time period.
