Zusammenfassung: | The present invention relates to a manufacturing method of methyl 3-mercaptopropionate comprises a step of reacting hydrogen sulfide with a mixture containing an organic solvent and methyl acrylate, in the presence of a catalyst containing a quaternary ammonium salt compound, wherein the organic solvent has heat of dissolution below 9.2 kcal/mol (room temperature, 1 atm) with respect to the methyl acrylate. In addition, the present invention relates to a manufacturing method of dimethyl 3,3′-thiopropionate comprises a step of reacting methyl 3-mercaptopropionate with a mixture containing an organic solvent and methyl acrylate, in the presence of a catalyst containing a quaternary ammonium salt compound, wherein the organic solvent has heat of dissolution below 9.2 kcal/mol (room temperature, 1 atm) with respect to the methyl acrylate.
