  • 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
