合成了一系列基于Zna[M(CN)b]c(M=Fe2+,Cr3+,Ni2+,Co3+,Mn3+,Mo4+,Cd2+和Fe3+)的双金属络合催化剂,并且用于催化环氧丙烷和二氧化碳的共聚反应,以研究中心金属对催化剂催化性能的影响。实验结果表明中心金属对催化剂催化性能影响很大,其中以Co3+,Ni2+为中心金属的催化剂具有较高的催化效能,分别达到2000和482g/g,而以Cd2+,Mn3+为中心金属的催化剂几乎没有催化活性。以Co3+,Ni2+,Fe3+为中心金属的催化剂能得到x(CO2)大于0.3的共聚物,而其它催化剂的共聚产物的x(CO2)小于0.1。
A series of bimetallic complex catalysts based on Zna [M (CN) b] c (M = Fe2 +, Cr3 +, Ni2 +, Co3 +, Mn3 +, Mo4 +, Cd2 + and Fe3 +) were synthesized and used to catalyze the oxidation of propylene oxide and carbon dioxide Copolymerization reaction to study the center of the metal catalyst on the catalytic performance. The experimental results show that the central metal has a great influence on the catalytic performance of the catalysts. Among them, the catalysts with Co3 + and Ni2 + as the central metal have higher catalytic performance, reaching 2000 and 482g / g, respectively, whereas the catalysts with Cd2 + and Mn3 + as the central metal have almost no Catalytic activity. Copolymers with x (CO2) greater than 0.3 were obtained with catalysts centered on Co3 +, Ni2 +, and Fe3 +, while the x (CO2) of the copolymerized products of other catalysts was less than 0.1.
