| titleOfInvention | Method for preparing polythiol compound, method for preparing curable composition, and method for producing cured product |
| abstract | Provided is a method for producing a polythiol compound, the method including: step 1 of reacting 2-mercaptoethanol having a water content of 3000 ppm or less on a mass basis, with epihalohydrin to obtain a halide represented by the formula (1), wherein X represents a halogen atom; step 2 of reacting the halide represented by the formula (1) with an alkali metal compound selected from the group consisting of an alkali metal sulfide and an alkali metal hydroxide to obtain a polyol compound selected from the group consisting of a polyol compound represented by the formula (2) and a polyol compound represented by the formula (3); step 3 of reacting the polyol compound with thiourea in the presence of an acid to obtain an isothiuronium salt; step 4 of hydrolyzing the isothiuronium salt in the presence of a base to obtain a polythiol salt; and step 5 of converting the polythiol salt into a polythiol by an acid to obtain at least one polythiol compound selected from the group consisting of a polythiol compound represented by the formula (4), a polythiol compound represented by the formula (5), a polythiol compound represented by the formula (6), and a polythiol compound represented by the formula (7). |
