Abstract
Abstract The aims of this investigation were the determination of stability constants of some dyes formed by reactions of imines with diazotized sulphanilic sodium salt at different pH values and temperatures . These stability constants were evaluated spectrophotometrically by reactions of donor imines in a forms of oxime or Schiff bases with sulphanilic sodium salt as an acceptor . This study led to a comparison between stability constants values of similar imines in a forms of syn or anti oximes or Schiff bases having substituents as OH , NH2 , NO2 and CH3 groups on aromatic ring of primary amine parts of Schiff bases . Finally , results collected were interpreted and discussed in detail .
