from malty steps, the first step converts mefenamic acid to their ester ethyl 2-((2,3-dimethylphenyl) amino) benzoate (T1) by reaction with ethanol catalyzed by sulfuric acid as a catalyzed. The hydrazide derivatives 2-((2,3-dimethylphenyl) amino) benzohydrazide (T2) prepared through the reaction ester(T1) with hydrazine hydrate in ethanol. Third step Prepared of some Schiff bases phenolic [T3-T5]
由麦芽糖步骤合成的新型酚醛树脂,第一步是通过与硫酸催化的乙醇反应将甲芬那酸转化为其2-((2,3-二甲基苯基)氨基)苯甲酸乙酯(T1)。通过酯(T1)与水合肼在乙醇中的反应制备的酰肼衍生物2-(((3,3-二甲基苯基)氨基)苯并酰肼(T2)。第三步制备一些席夫碱酚类[T3-T5],(E)-2-((2,3-二甲基苯基)氨基)-N'-(4-羟基-2-甲基亚苄基)苯甲酰肼(T3),(E )-2-(((2,3-二甲基苯基)氨基)-N'-(3-羟基-2-甲氧基亚苄基苯并酰肼(T4)和(E)-N'-(2,4-二羟基-6-甲基亚苄基)-2 -((2,3-二甲基苯基)氨基)苯甲酰肼(T5)最终制备了酚醛树脂[T6-T7],通过分批平衡法研究了这些聚合物的螯合能力,以萃取一些金属离子,例如Co + 2,Fe + 3,Ni + 2。研究了不同的因素,负载能力,PH和时间。通过使用各种光谱技术,例如FTIR,1
