  • 环氧乙烷水溶液和CO2合成碳酸乙烯酯:采用自行开发的NY-2催化剂，研究了环氧乙烷(EO)水溶液和CO2制备碳酸乙烯酯(EC)的反应性能。设计了正交实验以确定影响EO转化率和EC选择性的主要因素；探讨了溶剂EC用量、反应温度、反应压力、催化剂用量等因素对合成反应的影响。实验结果表明，n(H2O)∶n(EO)是影响EO转化率的最主要因素；温度和n(H2O)∶n(EO)是影响EC选择性的最主要因素；确定了采用NY-2催化剂、以EC为溶剂时， 合成反应的最佳工艺条件：反应温度100～120 ℃，反应压力3.0～4.0 MPa，催化剂质量分数2%，n(H2O)∶n(EO)=1∶2，n(EC)∶n(EO)=5。在此条件下，EO的转化率达到97.62%以上，EC的选择性达到92.55%左右。 作者：沈 玺，刘定华，刘晓勤 ------南京工业大学 材料化学工程国家重点实验室，江苏 南京 210009
