2Preparation of Ionic Liquid-immobilized HY Zeolite Catalysts and Application in the Synthesis of Propylene Carbonate显示文摘At first,NaY zeolite was modified to HY zeolite by ion exchange method,and then compound salt ion liquids were immobilized onto HY zeolite to prepare two immobilized ionic liquid catalysts HY-[HeMIM]Cl/(ZnBr_(2))_(2) and HY-[BMIM]Br/(ZnBr_(2))_(2).The synthesized immobilized ionic liquid catalysts were tested by FT-IR,XRD,TG and BET respectively.The results show that the prepared immobilized ionic liquids are the target product,have good thermal stability,and meet the requirements of catalysis.After immobilization,the intensity of crystallization peak is reduced,and the specific surface area becomes smaller.Conversion rate,selectivity and yield are as evaluation indicators to study the catalytic performance of immobilized ionic liquid catalysts for the synthesis of propylene carbonate from carbon dioxide and propylene oxide.Experimental results show that compound salt ion liquids were successfully immobilized on HY zeolite.Under the conditions of a temperature of 120℃,a pressure of 2.0 MPa,and a catalyst dosage of 2.0%,the catalytic effect of HY-[HeMIM]Cl/(ZnBr_(2))_(2) is better than HY-[BMIM]Br/(ZnBr_(2))_(2),and the conversion rate,selectivity and yield are 92.34%,98.87%and 91.30%.Lili SHI Xiaohui SONG Lining SHAN Changhui LI Liying GUO 2021Meteorological and Environmental Research2021,12,6:0
