制备方法与用途

用途

邻苯二甲酸铵是一种有机中间体，可通过邻苯二甲酸与氨水反应制得，主要用于合成邻苯二甲酰亚胺。邻苯二甲酰亚胺及其衍生物在有机化学合成中具有重要价值。它们被广泛应用于制备生物活性化合物（如抗菌剂、镇痛剂、抗真菌剂和植物生长调节剂），以及燃料工业。

制备 步骤 1：酸水解成邻苯二甲酸

将318克水加入配备有搅拌器和温度计的2升多颈烧瓶中，加热至95℃。同时，在1小时内向烧瓶内缓慢添加1.524克（占19.6%）邻苯二甲酸二钠水和301.8克硫酸。然后在该温度下搅拌混合物1小时，并冷却至20℃。

将所得的邻苯二甲酸进行结晶处理，在20℃下使用真空吸滤器进行抽滤，随后用215克水对其进行洗涤。

步骤 2：邻苯二甲酸转化为邻苯二甲酸铵

在吸滤器中将新洗涤过的邻苯二甲酸与89克水混合以形成均匀的混合物。接着，在70℃下，于1小时内向该混合物中加入221克20%氨水。最终生成了545克47%的邻苯二甲酸铵溶液（基于理论产率90%的邻苯二甲酸二钠），为了防止邻苯二甲酸铵结晶，将该溶液存放在高于55℃的温度下。
