| Abstract: | With acetylene and DEG as raw materials,and diethylene glycol potassium as the catalyst,using fixed-bed reactor and gas-liquid heterogeneous reaction process,the diethylene glycol divinyl ether and diethylene glycol divinyl ether were continuously synthesized.The suitable reaction conditions was determined by single-factor tuning:operating space velocity is 0.3 to 0.4 h-1,the system pressure ≥0.6 MPa,operating temperature is 175 ℃,potassium concentration is about 2%,diethylene glycol conversion rate ≥75%,the total yield of the product ≥72%. |
| Keywords: | diethylene glycol divinyl ether diethylene glycol divinyl ether diethylene glycol acetylene diethylene glycol potassium |
