| Popis: | New phenol formaldehyde resin synthesized 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], (E)-2-((2,3-dimethylphenyl) amino)-N'-(4-hydroxy-2-methylbenzylidene) benzohydrazide (T3), (E)-2-((2,3- dimethylphenyl) amino)-N'-(3-hydroxy-2-methoxybenzylidenebenzohydrazide(T4) and(E)-N'-(2,4-dihydroxy-6-methylbenzylidene)-2-((2,3-dimethylphenyl) amino) benzohydrazide (T5) finally prepared the phenol formaldehyde resins [T6-T7], The chelating ability of these polymers was studied to extract some metallic ions such as Co+2, Fe+3, Ni+2 by using batch equilibrium method. The different factors are studied, loading capacity, PH and time. All the synthesized compounds were characterized by using by various spectroscopic techniques such as FTIR, 1HNMR as well as DSC. |
