>Acid dissociation constants of some BETA -keto esters, viz. ethyl acetoacetate, ethyl alpha -phenyl acetoacetate, ethyl alpha - gamma -diphenyl acetoacetate, ethyl alpha -phenyl)phenylpropioloylacetate, ethyl alpha ( alpha -naphthyl)phenylpropioloylacetate, have been determined potentiometrically in 75 vol% dioxane-water media at 30 deg C. The 'thermodynamic'' stability constants of their chelates formed with Mn(II), Co(II), Ni(II), Cu(II), Zn(II) and U(VI) have also been determined. The effects of substituents in the BETA -keto ester on the equilibria are discussed. (auth)
