一种合成聚碳酸环己烯酯的高位阻席夫碱锌配合物催化剂
摘要：
本发明公开了一种合成聚碳酸环己烯酯的高位阻席夫碱锌配合物催化剂，所述催化剂为1,2-二（邻-水杨醛二亚胺-对羟基苯基）乙烷锌配合物，本发明制备的1,2-二（邻-水杨醛二亚胺-对羟基苯基）乙烷锌配合物是一种具有高位阻的席夫碱配合物，可以有效催化二氧化碳与氧化环己烯的共聚反应，具体步骤为：把氧化环己烯和上述催化剂加入高压釜中，然后通入2~5MPa的二氧化碳，机械搅拌，在80~150℃的条件下反应6~36h，冷却，倒入氯仿使聚合物溶解，滴加入甲醇中使聚合物沉淀析出，干燥得聚碳酸环己烯酯。本发明在上述的反应条件下催化效率最高达到204g聚碳酸环己烯酯/g催化剂，共聚物中聚碳酸酯摩尔含量超过90%。
摘要（英）：

The invention discloses a high hindered Schiff base zinc complex catalyst for synthesizing polycyclohexene carbonate. The catalyst is 1,2-bis(o-salicylaldimine-p-hydroxyphenyl) ethane zinc complex. The 1,2-bis(o-salicylaldimine-p-hydroxyphenyl) ethane zinc complex prepared by the invention is a Schiff base complex with high hindrance, and can effectively catalyze copolymerization reaction of carbon dioxide and cyclohexene oxide. Specific steps are as follows: adding the cyclohexene oxide and the catalyst to an autoclave, then introducing 2 to 5 MPa of carbon dioxide, mechanically stirring, andreacting at 80 to 150 DEG C for 6 to 36 hours, cooling and pouring into chloroform to dissolve polymer, dropping methanol to precipitate the polymer and drying to obtain the polycyclohexene carbonate. According to the high hindered Schiff base zinc complex catalyst for synthesizing the polycyclohexene carbonate, under the reaction conditions, catalytic efficiency is up to 204 g polycyclohexene carbonate/g catalyst, and molar content of polycarbonate in a copolymer exceeds 90%.
