production method | is obtained from the reaction of resorcinol with dichlorothioyl. Resorcinol and diethyl ether were mixed, heated to reflux with stirring, and dichlorosulfuryl was slowly added dropwise. Then warm to 60 degrees Celsius for 1H. The ether was recovered and then subjected to atmospheric distillation, and the distillate was further distilled under reduced pressure to collect a fraction of 131 ° C. (0.8-0.93kPa) or 160-164 ° C. (4.0kPa) to obtain a finished product. |
