Method for producing polythiol compound, method for producing curable composition, and method for producing cured product

Abstract

Provided is a method for producing a polythiol compound, including reacting 2-mercaptoethanol with an epihalohydrin, wherein the reaction is carried out in the presence of a halide selected from the group consisting of a 2,3-dihalogeno-1-propanol and an allyl halide, and an amount of the halide in the reaction is more than 0.50% by mass and 10.00% by mass or less with respect to the total amount of the halide and the epihalohydrin. Also provided are a method for producing a curable composition, including producing a polythiol compound by the abovementioned production method, and a method for producing a cured product, including producing a curable composition by the abovementioned production method.
