| titleOfInvention | The manufacture method of multi-thioalcohol compound, polymerizable composition for optical material and application thereof |
| abstract | The manufacture method of the multi-thioalcohol compound that the present invention relates to includes following operation: the polyol compound making following formula (4) represent and thiourea carry out reacting and obtaining the operation of isothiuronium salts in the presence of hydrogen chloride；While the reactant liquor containing the isothiuronium salts obtained being maintained the temperature of 20～60 DEG C while adding ammonia in 80 minutes in this reactant liquor, this isothiuronium salts is hydrolyzed, obtains with the operation of one or more multi-thioalcohol compounds as main constituent in the compound that following formula (6)～(8) represent；With addition 30～the hydrochloric acid of 36% concentration in the solution containing the multi-thioalcohol compound obtained, wash at a temperature of 30～55 DEG C, the operation of refined multi-thioalcohol compound. |
