Sažetak
In this paper a single step synthesis of 3- hydroxy-1-(p-methoxyphenyl)-2-methylpyridine-4- one (HM) using starting maltol and p-anisidine in the presence of acid catalyst (p- toluenesulfonic acid or HCl) is described. The reaction is carried out by heating the aqueous solution of the reactants and a catalyst in a sealed thick-walled glass tube at 150 °C at different reaction times in order to retrieve an optimal yield. The complexation reactions of vanadium(V) with HM as well as the extraction of V(V) from aqueous to organic phase were studied spectrophotometrically. The optimum conditions for extraction of vanadium(V) from aqueous phase, containing chloride or thiocyanate ions, to chloroform solution of HM and complex formation have been evaluated. Based on the results obtained by Job’s and equilibrium shift methods the composition of the complexes has been found to be V(V) : Cl(SCN) : HM = 1:1:2.
