【摘要】 以对苯二甲酸二酯与对苯二胺为原料,氢化钠为催化剂,合成了一种芳香性二酰胺二胺化合物。与其他对苯二甲酸二酯相比,对苯二甲酸二甲酯在40℃下有较高的活性,和对苯二胺反应生成N,N′-双(对氨基苯基)对苯二甲酰胺的产率在60%以上。反应产物的结构分别用元素分析,IR和1HNMR进行了表征。更多还原

【Abstract】 A novel aryldiamidediamine was synthesized by using sodium hydride as catalyst,1,4-phenyleneamine and a series of terephthalic acid esters as starting materials.The dimethyl terephthalate was found to be the most active among those terephthalic acid esters used to react with 1,4-phenyleneamine at 40℃ to produce the N,N′-bis(p-aminophenyl)terephthalamide.The component and structure of the product were characterized by using elemental analysis,IR and 1HNMR .更多还原
