摘　　要：利用4-硝基邻苯二甲腈的亲核取代反应合成含羟基的邻苯二甲腈衍生物4-(2-羟基苯氧基)邻苯二甲腈(2o),4-(3-羟基苯氧基)邻苯二甲腈(2m),4-(4-羟基苯氧基)邻苯二甲腈(2p)。傅立叶变换红外光谱(FT-IR)和核磁共振氢谱(1HNMR)的分析结果证明了所得化合物的化学结构;示差热分析(DSC)和热失重分析(TGA)分别对化合物的热固化行为进行了表征。A series of novel phthalonitrile derivatives containing amino groups were synthesized via nucleophilic displacement of 4-nitrophthalonitrile and phenolic derivatives：4-（2-hydroxyl phenoxy）phthalonitrile（2o）,4-（3-hydroxyl phenoxy）phthalonitrile（2m）,4-（4-hydroxyl phenoxy）phthalonitrile（2p）.The structures of these phthalonitrile-based compounds were confirmed by FT-IR and 1H NMR.Differential scanning calorimetry（DSC）and thermogravemetric analysis（TGA）were used to investigate thermal behaviors of these compounds.The results indicate that protonation（viz.,acidity）of hydroxyl groups make remarkable contributions to the cure reactions.
