There is provided a process for preparing β-mercaptocarboxylic acid represented by the following General Formula (3) comprising step of reacting hydrogen sulfide, alkali hydroxide represented by a formula: XOH (X represents Na or K), and unsaturated carboxylic acid represented by the following General Formula (1) under atmospheric pressure to obtain a reaction solution including a compound represented by the following General Formula (2) and step of neutralizing the reaction solution in an acid. An amount of the alkali hydroxide is equal to or greater than total moles of the unsaturated carboxylic acid and the hydrogen sulfide.
提供了一种制备β-巯基羧酸的过程,该过程包括以下一步:在大气压下,反应硫化氢、碱性氢氧化物(表示为XOH,其中X代表Na或K)和不饱和羧酸(表示为通用公式(1))以获得包含一种化合物(表示为通用公式(2))的反应溶液,以及在酸性条件下中和反应溶液。碱性氢氧化物的量等于或大于不饱和羧酸和硫化氢的总摩尔数。
