Yield:7580-85-0 97.3%

Reaction Conditions:

with K-MgO/γ-alumina in tetrahydrofuran at 50; for 5 h;Temperature;

Steps:

1-3 S2. Preparation of ethylene glycol mono-tert-butyl ether

Add 8mol tert-butanol (592g) and 8g of K-MgO / γ-alumina solid base prepared in step S1 to the reaction kettle,After stirring well, after raising the temperature to 50 ,Slowly add 2L of 0.5moL / L ethylene oxide tetrahydrofuran solution dropwise. After the dropwise addition, keep the reaction for 5 hours.After the reaction, the solid base was removed by filtration,Distillation under reduced pressure gave 114.8 g of high-purity ethylene glycol mono-tert-butyl ether with a yield of 97.3% (calculated as ethylene oxide).
