Abstract

This production method for a polythiol compound comprises: a step in which the polyalcohol compound represented by formula (4) 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 20- 60 °C and aqueous ammonia is added to said reaction solution within 80 minutes , the isothiuronium salt is hydrolyzed, and a polythiol compound is obtained that comprises one or more of the compounds selected from the group consisting of the compounds represented by formulas (6) -(8) as a main component thereof; and a step in which hydrochloric acid having a concentration of 30- 36% is added to a solution containing the obtained polythiol compound and washing is carried out at a temperature of 30- 55 °C in order to purify the polythiol compound.
