| 摘 要： | 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碱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。

| Abstract: | In this paper, five 4-amino-3, 5-disubstituted-1, 2, 4-triazoles and four Schiff basesprepared from the triazoles and p-hydroxy benzaldehyde were used as catalysts for reactionof carbon dioxide with oxirane to ethylene carbonate. Their catalytic activity were evaluated by comparing their structure and basicity. The mechanism of the reaction has also been discussed.The results indicated that the order of catalytic activity was in agreement with the basicity of nitrogenous organic bases: Schiff bases>triazoles. |
