To obtain the subject compound for powder coating, adhesives, curing agents in high yield by reacting allyl methacrylate with hydrogen peroxide in the presence of a solid catalyst in a solvent, separating the catalyst and washing the reaction product with water or an alkali aqueous solution and distilling the product.
Allyl methacrylate is reacted with dropped hydrogen peroxide at 60°C in one or more kinds of solvents selected from methanol and acetone or methanol, methylethyl ketone, etc., in the presence of a solid catalyst comprising titanosilicate, etc., having MFI crystalline structure and prepared by adding tetrapropylammonium hydroxide aqueous solution to tetraethyl orthosilicate and heating these components at 210°C in an autoclave and carrying out baking treatment of these components at 550°C and the reactional liquid is filtered to remove a solid catalyst and the solution is washed with water or alkali aqueous solution and distilled to provide the objective glycidyl methacrylate useful as a raw material for powder coating, an adhesive, a curing agent, a modifier, etc., in a high yield.
