PURPOSE:To readily and efficiently obtain the subject compound useful as a raw material for polymers used as plastics, etc., in high yield without causing coloring and side reaction by reacting acrylic acid, etc., with a hydroxy compound using a specific metal as a catalyst. CONSTITUTION:Acrylic or methacrylic acid is reacted with a hydroxy compound, e.g., aliphatic, alicyclic, aromatic alcohol or phenols, preferably using metallic tin and/or metallic lead which are powdery simple metallic substance having a particle diameter passing through a wire net of preferably 100 mesh, as necessary, in the coexistence of a polymerization inhibitor, e.g., methoxyhydroquinone, and a solvent, e.g., toluene or mixed xylene, at 80-250 deg.C for 0.5-20hr under atmospheric pressure to carry out esterification and afford the objective compound useful as a raw material for polymers used as coatings, adhesives, paper processing treating agents, lubricating oil additives, inks, etc. Furthermore, the undissolved catalyst is separated by filtration and circulated for reuse. |
