离子液体催化CO2与环氧丙烷合成碳酸丙烯酯反应动力学研究
Study on reaction kinetics of synthesizing propylene carbonate from carbon dioxide and propylene oxide catalyzed by ionic liquids
摘要
Abstract
The self-made alkyl functionalization catalyst was prepared and applied in the cycloaddition reaction of propylene oxide(PO)and CO2 to propylene carbonate(PC).The catalyst amount,the reaction temperature,the reaction pressure and the reaction time were optimized.The reaction mechanism was derived.The kinetic equation was established.And the relationship of PO conversion and PC yield with time at different temperatures was discussed.The experimental results show that the PO conversion and the PC yield can reach 99.61%and 99.25%respectively when the catalyst amount is 0.8%(w),the reaction temperature is 140℃,the reaction pressure is 4.0 MPa,and the reaction time is 2.0 h.The reaction rate of PC synthesis exhibits a linear relationship with the concentration of PO and follows the first-order reaction kinetics law.关键词
