    • The invention relates to a method for efficiently producing β-mercaptocarboxylic acids using a solid acid catalyst such as zeolite, which product corresponds to respective starting materials selected from α, β-unsaturated carboxylic acids (α, β-unsaturated carboxylic acid, α, β-unsaturated carboxylic acid ester, ex, β-unsaturated amide, α, β-unsaturated aldehide and α, β-unsaturated ketone) and hydrogen sulfides (hydrogen sulfide, sulfide salt and hydrosulfide salt), wherein a solvent compatible with water is used in the reaction. According to the invention, β-mercaptocarboxylic acids which are useful as additives in synthetic materials for pharmaceutical or agricultural agents and in polymer compounds can be industrially produced efficiently by using easily available a, β-unsaturated carboxylic acid (such as crotonic acid) at high yield.
    • 本发明涉及一种使用沸石等固体酸催化剂有效生产β-巯基羧酸的方法,该产物对应于选自α,β-不饱和羧酸(α,β-不饱和羧酸,α,β 不饱和羧酸酯,β-不饱和酰胺,α,β-不饱和醛和α,β-不饱和酮)和硫化氢(硫化氢,硫化物盐和氢硫化物盐),其中使用与水相容的溶剂 反应。 根据本发明,用作药物或农药的合成材料和聚合物化合物的合成材料中的添加剂的β-巯基羧酸可以通过在高温下使用容易获得的β-不饱和羧酸(例如巴豆酸)而有效地生产 产量。
