Reaction Conditions:
with thionyl chlorideReflux;
Steps:
1.1-4.1 (1) Synthesis of 2,2-dichloroethyl ether
In a 250 mL four-neck round bottom flask equipped with a magnetic stir bar, thermometer, reflux condenser and constant pressure drop tube with an exhaust gas absorption device, 0.5 mol of diethylene glycol was added, 1.1 mol of thionyl chloride was slowly added dropwise with stirring, and the addition was completed after 20 min, and the mixture was heated to reflux, and reacted for 3-4 h until no gas escaped. An excess of thionyl chloride was distilled off under normal pressure, and then 70-72 ° C / 5 mmHg was collected by distillation under reduced pressure to give a transparent liquid, yield (yield of diethylene glycol) 86%.
