Polythiol compound and method for producing same
According to the present invention, a polythiol compound having a total nitrogen content of 50 to 600 ppm inclusive can be provided. According to the present invention, a method for producing the polythiol compound can also be provided, said method being characterized by comprising the steps of: reacting a polyalcohol with thiourea to prepare a thiuronium salt; and adding at least one base selected from the group consisting of hydrazine (hydrate), ammonia and an amine and an inorganic base (that is different from hydrazine (hydrate) or ammonia) to the thiuronium salt in the presence of an organic solvent to hydrolyze the thiuronium salt.
