| 摘 要： | 采用类叶绿素化合物四苯基镁卟啉(MgTPP)为催化剂,研究了超临界CO2介质中CO2与系列环氧化物偶联合成环碳酸酯的反应。研究发现MgTPP在超临界CO2介质中表现出很高的催化活性,其TOF(活性转化频率)最高可达18 989 h-1。在优化的反应条件(环氧化物:0.2 mol,三乙胺:5×10-6 mol,MgTPP:1×10-5 mol,P:7.5 MPa,T:140℃t,:1 h)下,主产物环碳酸酯的选择性均超过97%,收率则在74%～94%之间。 |

| Abstract: | The synthesis of cyclic carbonates by coupling reactions of supercritical CO2 with epoxides catalyzed by a type of chlorophyll-like catalyst,magnesium porpyrin were investigated.Magnesium meso-tetraphenylporphyrins(MgTPP) were discovered to performe highly catalytic activity in supercritical CO2,and the maximum of TOF(turnover frequency) was 18 989 h(-1).When the reactions were carried out under the optimal condition(epoxide:0.2 mol,triethylamine:5×10(-6) mol,MgTPP:1×10(-5) mol,P:7.5 MPa,T:140 ℃,t:1 h),the selectivity of the main products,cyclic carbonates,was up to 97%,and the yields of cyclic carbonates could reach up to 74%—97%. |
| Keywords: | magnesium porphyrin chlorophyll-like catalyst supercritical CO2 epoxide cyclic carbonate |
