Abstract:
A new 2.6-diaryl piperidone-4 ligand 2,2'-(3,5-dimethyl-4-oxopiperidine-2,6-diyl)bis(2,1-phenylene) dibenzenesulfonate was synthesized by reaction of 2,6-bis(2-hydroxyphenyl)-3,5-dimethylpiperidin-4-one with benzenesulfonyl chloride in ratio (1:2), The purity of the compounds was confirmed by TLC. the compounds has been characterized by elemental analyses IR, mass, 1H-NMR, and 13C-NMR spectral data. , these compound were evaluated for their In vitro activity against several microbes( Staphylococcus aureus , Bacillus. subtilis , Escherichia Coli and Klebsiella pneumonia) .these compound were tested to determine their ability to inhibit corrosion of mild steel in 1 mol.l-1 H2SO4 by Electrochemical measurements. The compound has been studied by liquid-liquid extraction towards the metal ion Cu2+ from aqueous phase to organic phase. behave as good extractant ligand for Cupper ion Cu2+ from aqueous solution, and the study of condition of extraction shows that the optimum pH values for extraction was (pH= 10), so the suitable concentration of Cu2+ ion in aqueous solution which is giving highest distribution ratio (D) was (40 μg), in addition the optimum shaking time to reach the equilibria was (60 min.), as well as the stoichiometric study by using Slope Analysis Method shows the structure of Cu2+ ion complex with ligand was 1 : 1 (metal : ligand), in addition the study of organic solvent effect appear there is no straight line relation between the distribution ratio for extraction of Cu2+ ion and dielectric constant for organic solvents but this study demonstrate there is an effect for the structure of organic solvent used, thermodynamic study shows the complexation reaction an endothermic
