摘要： A method for producing MMA-d8 which comprises a step of exchanging D in the hydroxyl group of methanol-d4 represented by the formula: CD3OD with H to prepare the methanol-d3 represented by the formula: CD3OH and simultaneously recovering a deuterium-containing compound, and a step of reacting the methanol-d3 with a sulfuric acid salt of methacrylic acid amide represented by the formula CD2=C(CD3)CONH2·H2SO4, to prepare MMA-d8 represented by the formula: CD2=C(CD3)COOCD3. The above method can be employed for producing MMA-d8 with good efficiency while circulating expensive deuterium atoms being by-produced in an above reaction process .
