合成五种4-氨基-3，5-二取代-1，2，4-三唑及四种与对羟基苯甲醛缩合的Schiff碱，作为含氮有机碱催化剂，用来催化由二氧化碳与环氧乙烷合成碳酸乙烯酯的反应．通过结构特点和碱性强弱解释评价其催化活性，并且对反应机理进行了初步探讨．实验结果表明，催化活性顺序：三唑Schiff碱＞4-氨基-3，5-二取代-1，2，4-三唑，这与含氮有机物碱性大小是一致的． Five kinds of 4-amino-3,5-disubstituted-1,2,4-triazoles and four kinds of Schiff bases condensed with p-hydroxybenzaldehyde were synthesized and used as nitrogen-containing organic base catalysts to catalyze the condensation of carbon dioxide with epoxy Ethane synthesis of ethylene carbonate reaction. The catalytic activity was evaluated by the structural characteristics and alkaline strength. The reaction mechanism was also discussed. The experimental results show that the order of catalytic activity is: triazole Schiff base> 4-amino-3,5-disubstituted-1,2,4-triazole, which is consistent with the basic size of nitrogenous organic compounds.
