Facile process for the production of 3-mercaptopropionitrile and 3-mercaptopropionic acid by reacting thiodipropionitrile with alkaline hydrosulfide in the presence of alkaline hydroxide. Acidification of the resulting reaction product with a strong acid, or saponification, yields the desired mercaptopropionic acid, which can be isolated in high yield.
通过在碱性氢硫化物和碱性氢氧化物的存在下将硫代丙腈与反应,制备3-巯基丙腈和3-巯基丙酸的简易工艺。用强酸酸化反应产物或皂化可以得到所需的巯基丙酸,可以高收率地分离。
