| titleOfInvention | The manufacturing method of multi-thioalcohol compound, polymerizable composition for optical material and application thereof |
| abstract | This application involves the manufacturing methods of multi-thioalcohol compound, polymerizable composition for optical material and application thereof.The manufacturing method of multi-thioalcohol compound of the present invention comprises the following steps: the polyol compound for indicating following formula (4) is reacted the process for obtaining isothiuronium salts with thiocarbamide in the presence of hydrogen chloride；Exist while by 20~60 DEG C of temperature is maintained containing the obtained reaction solution of isothiuronium salts and ammonium hydroxide is added into the reaction solution in 80 minutes, the isothiuronium salts is hydrolyzed, is obtained with the process for the multi-thioalcohol compound that one or more of the compound indicated selected from following formula (6)~(8) is principal component；With the hydrochloric acid that 30~36% concentration are added in containing the obtained solution of multi-thioalcohol compound, 30~55 DEG C at a temperature of wash, the process for refining multi-thioalcohol compound. |
