Room Temperature Synthesizable ZIF-71 Catalyst for the Solvent Free Synthesis of Cyclic Carbonates from Epoxides and CO2 |
| 초록 |
Development of heterogeneous catalyst systems capable of materializing the CO2 - epoxide cycloaddition reactions under mild reaction conditions is highly desirable. Synthesis of cyclic carbonates from CO2 and epoxides is 100% atom economical and is the most promising pathway since it avoids the use of toxic raw materials such as phosgene or isocyanates. While CO2 is considered to be a thermodynamically and chemically stable molecule under standard conditions, the inertness of CO2 has to be breakdown via catalysis. Zeolitic imidazolate frameworks (ZIF's) are a subclass of metal organic frameworks (MOFs) generally made from imidazolate linkers and tetrahedrally coordinated metal atoms such as Co and Zn. In this work, ZIF-71 was synthesized under room temperature conditions instantly and was characterized using various physicochemical properties. The cycloaddition reactions were performed by using different epoxides under room temperature conditions. The effect of various reaction parameters such as the temperature, catalyst loading, CO2 pressure, and time were evaluated. A plausible reaction mechanism also was also proposed. |
