查询词典 methionine

Results The synthesis condition was improved. The method of methane sulfonic acid/DL-methionine was found an ideal substitute of BBr3 for less cost. While using hydrobromic acid, the O-demethylation and hydrolyzation could be combined in one stage.

结果 优化了纳洛酮的合成工艺，甲磺酸／DL-甲硫氨酸法试剂价格低廉，可降低生产成本；而氢溴酸法不但试剂价格更低，还可将去氧甲基化和水解合并为一步反应，使新工艺的总收率提高到59.90%，产品质量符合中国药典。
