摘要
以芴为主要原料,经过醚化、酯化和Friedel-Crafts酰基化等反应,合成出了9,9-双羟甲基芴、9,9-双甲氧甲基芴、丁二酸单乙酯和丁二酸单乙酯酰氯4种中间体,并最终合成出目的产物2-丁二酸单乙酯酰基-9,9-双甲氧甲基芴。采用核磁共振对中间体和目的产物的结构进行了表征和分析。最后以2-丁二酸单乙酯酰基-9,9-双甲氧甲基芴为内给电子体合成出新型聚丙烯催化剂,采用丙烯液相本体聚合的方法,对催化剂催化丙烯聚合反应的性能进行了评价。
Four intermediate products, 9, 9-bis-（ hydromethyl ） fluorene, 9, 9-bis （ methomethyl ） fluorene, monoethyl succinate and monoethyl succinyl chloride, were synthesized via etherification, esterification and Friedel-Crafts acylation, using fluorene as the starting material. 2-monoethyl succinyl-9,9- bis（methoxymethyl）fluorene was finally synthesized as the end product. The intermediate products and end product were characterized by 1H-NMR and ^13 C-NMR. A novel propylene polymerization catalyst was synthesized using 2-monoethyl succinyl-9,9- bis（methoxymethyl） fluorene as the internal electron donor and the performance of the catalyst was tested for propylene bulk polymerization.
