    An object of the present invention is to provide a method for industrially producing beta-mercapto carboxylic acids that are useful as synthetic raw materials for medicines and agrochemicals or as additives for polymer compounds from easily available alpha,beta-unsaturated carboxylic acids in high yields and productivity. The present invention is characterized in that a solvent having an amide group and represented by the formula (1) is used when the alpha,beta-unsaturated carboxylic acids are reacted with hydrogen sulfides to produce the beta-mercapto carboxylic acids. Particularly, it is more preferable to carry out the reaction at a pH range of 6.0 to 8.5: (In the formula (1), R1 represents any one of a hydrogen atom, an alkoxy group having 1 to 5 carbon atoms, an alkyl group having 1 to 5 carbon atoms, an amino group, and an alkylamino group having 1 to 5 carbon atoms; R2 and R3 each represents independently any one of a hydrogen atom and an alkyl group having 1 to 5 carbon atoms; when both R2 and R3 are not a hydrogen atom, R2 and R3 may together form a ring structure through an alkylene group; and when both R1 and R2 are not a hydrogen atom, R1 and R2 may form a ring structure through an alkylene group).
    本发明的目的是提供一种工业生产β-巯基羧酸的方法,该方法可以从易得到的α,β-不饱和羧酸高产高效地合成用于药品和农药的合成原料或聚合物化合物的添加剂。本发明的特点在于,在α,β-不饱和羧酸与氢硫化物反应产生β-巯基羧酸时,使用具有酰胺基的溶剂,该溶剂由公式(1)表示。特别是,在pH范围为6.0至8.5的条件下进行反应更为理想:(在公式(1)中,R1代表氢原子、具有1至5个碳原子的烷氧基、具有1至5个碳原子的烷基、氨基和具有1至5个碳原子的烷基氨基中的任意一种;R2和R3各自独立地代表氢原子和具有1至5个碳原子的烷基中的任意一种;当R2和R3均不是氢原子时,R2和R3可以通过烷基链结构形成环状结构;当R1和R2均不是氢原子时,R1和R2可以通过烷基链结构形成环状结构。)
