一种新型二氧化碳与环氧丙烷共聚催化剂的合成与性能研究

Study on Synthesis and Properties of a New Catalyst for Copolymerization of Carbon Dioxide and Propylene Oxide

合成了一种SalenCo催化剂,并利用红外光谱、质谱以及核磁共振氢谱等对其进行表征.此外,探究了在不同反应温度、CO_2压力、反应时间和催化剂用量下,该催化剂对二氧化碳与环氧丙烷共聚的影响,得到了合成聚碳酸酯的最佳反应条件.

A new Schiff base cobalt catalyst was synthesized and characterized by IR,ESIMS,and ~1H NMR. In addition,the influences of the catalyst on the copolymerization of carbon dioxide and propylene oxide under different reaction temperature,CO_2 pressure,reaction time and catalyst dosage were investigated. The optimum reaction conditions for synthesizing polycarbonate were obtained.
