  Article:   LOGARITHMIC EXTRAPOLATION METHOD FOR KINETIC DETERMINATION OF AMINE MIXTURES.

Authors:  LUCIAN COPOLOVICI, I. BALDEA.
 
       
         
  Abstract:  A kinetic method for the simultaneous determination of binary mixtures of aromatic amines and of -naphtol and 1-phenyl-3-methylpyrazolin-5-one by logarithmic extrapolation is reported. The method involves the formation of an azo dye between coupling agent and a diazonium salt formed from the amine in the presence of nitrite in weak acidic media. The reaction is monitored spectrophotometrically by the formation of an azodye absorbing at 420 nm.
