| titleOfInvention | Method for producing beta-mercaptocarboxylic acid |
| abstract | To provide [beta]-mercaptocarboxylic acids which are useful as additives in synthetic raw materials for pharmaceutical or agricultural agents and in polymer compounds and can be industrially produced efficiently by using as a raw material an easily available [alpha],[beta]-unsaturated carboxylic acid (such as crotonic acid) in a high yield. The invention relates to a method for efficiently producing [beta]-mercaptocarboxylic acids using a solid acid catalyst such as zeolite, which product corresponds to respective starting raw materials of [alpha],[beta]-unsaturated carboxylic acids (an [alpha],[beta]-unsaturated carboxylic acid, an [alpha],[beta]-unsaturated carboxylic acid ester, an [alpha],[beta]-unsaturated amide, an [alpha],[beta]-unsaturated aldehyde and an [alpha],[beta]-unsaturated ketone) and hydrogen sulfide etc. (hydrogen sulfide, sulfide salt and hydrosulfide salt), wherein a solvent compatible with water is used as the reaction solvent. |
