解决方案:使用易获得的甲醇-d4和丙酮-d6作为原料制造甲基丙烯酸-d8,其中所有氢原子均被氘代替,其中甲醇-d4被转化为其甲基完全氘代的甲醇-d3,然后从得到的甲醇-d3中获得其甲基完全氘代的甲基丙烯酸-d8,并使用从丙酮-d6制备的丙酮氰醇-d6。当甲醇-d4转化为其甲基完全氘代的甲醇-d3时,回收的含氘化合物被重新利用作为制造甲醇-d4和丙酮-d6的部分原料。

PROBLEM TO BE SOLVED: To provide an economical manufacturing method of methyl methacrylate-d8 (C
SOLUTION: Methyl methacrylate-d8 is manufactured using as raw materials readily available methanol-d4 and acetone-d6 with all hydrogen atoms thereof deuterated, where methanol-d4 is converted into methanol-d3 with its methyl group fully deuterated and methyl methacrylate-d8 is obtained from the thus-obtained methanol-d3 with its methyl group fully deuterated and acetone cyanhydrin-d6 prepared from acetone-d6. A deuterium-containing compound, recovered when methanol-d4 is converted into methanol-d3 with its methyl group fully deuterated, is reutilized as a part of raw materials for manufacturing methanol-d4 and acetone-d6.
