Synthesis method

Derived from the reaction of resorcinol and dichlorosulfonyl. Mix resorcinol and diethyl ether, stir and heat to reflux, and slowly add sulfur dichloride dropwise. Then raise the temperature to 60°C and keep warm for 1 hour. After recovering the ether, distill it under normal pressure, then distill the distillate under reduced pressure, and collect the 131°C (0.8-0.93kPa) or 160-164°C (4.0kPa) fraction to obtain the finished product.


Used for organic synthesis, preparation of various ether derivatives, drawings and analytical reagents.
