己二酸锌的制备及其对二氧化碳和环氧丙烷共聚反应的催化活性

摘要

Zinc adipate catalysts used for the copolymerization between CO2 and propylene oxide were synthesized via several synthetic routes. WXRD determination indicated zinc adipate from zinc oxide exhibited high degree of crystallinity and crystal quality, according-ly produced poly (propylene carbonate) (PPC) with a high yield of 88.3 g per gram of catalyst. The NMR spectra revealed the ob-tained PPC having a highly alternating copolymer structure.%通过不同锌源(氧化锌、氢氧化锌、碳酸锌、乙酸锌)与己二酸反应制备己二酸锌催化剂.WXRD的分析表明由氧化锌制备的己二酸锌拥有较高的结晶度和结晶质量,因此在催化二氧化碳和环氧丙烷共聚反应中显示较高的活性,每g催化剂可产生88.3 g聚合物.核磁共振谱测试显示所得聚合物PPC具有高度的交替结构.
