Reaction Conditions:
with pyridine;thionyl chloride in 1,4-dioxane at 80;
Steps:
Preparation of dichloroethylene glycol,Specifically, the following steps are included
General procedure: S1, 1mol of diol and 3mol of pyridine are dissolved into 500mL of dioxane, and heated, heated to 80 ° C;S2, adding 2.2 mol of thionyl chloride to the product in step S1, slowly dropping, adding 2-3 h, and after the completion of the dropwise addition, reacting at 80 ° C for 5-6 h;S3, the product solution in step S2 is naturally cooled to room temperature, and dioxane is distilled off;S4, the residue in step S3 is added to ethyl acetate, stirred for 30 min, and the pyridinium salt is filtered off;S5. The filtrate in the step S4 was washed with water, and the ethyl acetate layer was dried over anhydrous sodium sulfate and evaporated.
