Abstract:
1. A process for producing a hydroxyalkyl(meth)acrylate which comprises reacting a (meth)acrylic acid with an alkylene oxide in the presence of a catalyst in a reaction liquid, a condition wherein an amount of an acid component gives a value calculatively not less than 0.010 in terms of a molar ratio to an amount of the catalyst being maintained not only during the reaction, but in cooling in the end of the reaction, in a standby period until evaporation of the hydroxyalkyl(meth)acrylate product, and in and after evaporation of the hydroxyalkyl(meth)acrylate product, a reaction liquid after evaporation of the hydroxyalkyl(meth)acrylate therefrom is used for a subsequent reaction, and the catalyst is a homogeneous catalyst that is chromium (Cr) compound.
