Second, the Synthetic Route we will recommend is the most important for your reference?

Synthesis route in the lab，

Add 30mL of glacial acetic acid, 93g (0.5mol) of 1,2-dibromoethane, 98g (1.0mol) of freshly calcined potassium acetate, and 1.5g of pyridine to a reaction flask equipped with a stirrer and reflux condenser. Stir and heat for reflux for 3 hours. Change to a distillation device and evaporate the volatile part until the distillation is complete. Add 2mL of glacial acetic acid, 93g (0.5mol) of 1,2-dibromoethane, 98g (1.0mol) of freshly calcined potassium acetate, and 1.5g of pyridine to the distillate, then stir and heat for reflux for 3 hours. Change to a distillation device for distillation, collecting various fractions as follows: fractions before 140 ℃; Distillate at 140~170 ℃ (30~39g);Distillate at 170~190 ℃ (70~78g). Redistille the fractions from 140 to 170 ℃ and collect (10-16g) from 170 to 190 ℃. Combine the fractions from 170 to 190 ℃ for distillation, collect the fractions from 180 to 190 ℃, and obtain 80-90g of ethylene glycol diacetate,collecting 55% to 61%.

 

Other chemical synthesis route，

 

1. It is obtained by reacting 1,2-dibromoethane with potassium acetate.

2. Produced by the reaction of ethylene glycol and acetic anhydride. The main impurity is ethylene glycol monoacetate. When refining, dry with calcium chloride and anhydrous potassium carbonate, and then distill under reduced pressure
