| titleOfInvention | The manufacturing method of multi-thioalcohol compound, polymerizable composition for optical material and application thereof |
| abstract | Manufacturing method, polymerizable composition for optical material the present invention relates to multi-thioalcohol compound and application thereof, the manufacturing method of multi-thioalcohol compound of the present invention include following process：The epihalohydrin compound that 2 mercapto ethanol is represented with the following general formula (1) is made to be reacted the process for the polyol compound for obtaining following formula (2) expression at a temperature of 10~50 DEG C；The polyol compound made is reacted with thiocarbamide in the presence of hydrogen chloride obtains the process of isothiuronium salts；While the reaction solution containing obtained isothiuronium salts is maintained 15~60 DEG C of temperature while adding in ammonium hydroxide into the reaction solution in 80 minutes, which is hydrolyzed, obtains the process of the multi-thioalcohol compound of following formula (5) expression；Hydrochloric acid with 25~36% concentration are added in into the solution containing obtained multi-thioalcohol compound, is washed at a temperature of 10~50 DEG C, the process for refining multi-thioalcohol compound. |
