METHOD FOR PRODUCING DEUTERATED METHYL METHACRYLATE

摘要

A method for producing MMA-d 8 which includes a step of exchanging D in hydroxyl group of methanol-d 4 represented by the formula: CD 3 OD with H to prepare the methanol-d 3 represented by the formula CD 3 OH and simultaneously recovering a deuterium-containing compound, and a step of reacting methanol-d 3 with sulfuric acid salt of methacrylic acid amide represented by the formula CD 2 =(CD 3 )CO(NH 2 ·H 2 SO 4 ) to prepare MMA-d 8 represented by the formula: CD 2 =(CD 3 )COOCD 3 .
