| titleOfInvention | Catalyst for synthesizing propylene glycol ether and preparation method thereof |
| abstract | The invention relates to the technical field of chemical catalysis, and discloses a catalyst for synthesizing propylene glycol ether, wherein the catalyst is polyvinyl imidazole-divinylbenzene, and the preparation method comprises the following steps: adding azodiisobutyronitrile, N into an ethyl acetate solution of 1-vinylimidazole with the concentration of 0.5-1.2 mol/L 2 Or heating to 65-90 ℃ under inert gas, keeping the temperature for 0.5-2 h, adding an ethyl acetate solution of divinylbenzene, keeping the temperature for 12-24 h at 65-90 ℃, cooling, and drying a product to obtain the catalyst for synthesizing the propylene glycol ether, wherein the addition amount of the azobisisobutyronitrile is 0.01-5 wt% of 1-vinyl imidazole, and the molar ratio of the 1-vinyl imidazole to the divinylbenzene is 1: 0.01 to 20. The obtained catalyst for synthesizing propylene glycol ether has the advantages of high activity, high selectivity, low energy consumption, easy separation and the like, and is low in production cost and suitable for industrial production. |
