Abstract

This production method for a polythiol compound comprises: a step in which 2- mercaptoethanol and an epihalohydrin compound represented by general formula (1) are reacted at a temperature of 10- 50 °C in order to obtain a polyalcohol compound that is represented by formula (2); a step in which the obtained polyalcohol compound and thiourea are reacted in the presence of hydrogen chloride in order to obtain an isothiuronium salt; a step in which the temperature of a reaction solution containing the obtained isothiuronium salt is maintained at a temperature of 15- 60 °C and aqueous ammonia is added to said reaction solution within 80 minutes the isothiuronium salt is hydrolyzed, and a polythioi compound represented by formula (5) is obtained; and a step in which hydrochloric acid having a concentration of 25- 36% is added to a solution containing the obtained polythmol compound and washing is carried out at a temperature of 10- 50 °C in order to purify the polythiol compound.
