Synthesis of Cyclic Carbonates Catalyzed by Hydrogen Donor Based Catalyst |
| 초록 |
The synthesis of cyclic carbonate from CO2 and epoxide catalyzed by ionic liquids (ILs) has attracted much more attention in recently years. In the early reseach, we found that water could promote the cycloaddition of CO2 and epoxides, and the corresponding reaction rate could be enhanced by 5-6 times compared to that in the absence of water. As a continous work, some hydrogen bond based catalyst were synthesized and used for further investigation on the synergistic effect. It was found that general OH-group containing solvet chemicals could also enhance the activity of tradition catalysts for the synthesis of cyclic carbonates without metal halide. The prepared ILs functionalized with hydrogen bond donors (e.g. -OH, -COOH) exhibited excellent catalytic performances comparing to the traditional ILs with respect without co-catalyst and co-solvent. Thereafter, highly active and stable molecular sieve and polymer supported functionalized IL catalysts were developed, and successfully applied them in a 500h fix-bed test. Based on the above previous results, a synergistic activate effect of hydrogen bonding on the ring-opening of epoxide was proposed. |
