    • Abstract

       

      N-hydroxy-N-phenyl-N′-(2-methyl)phenylbenzamidine hydrochloride reacts with iron (III) in the presence of thiocyanate and azide forming coloured mixed complexes which are quantitatively extractable into benzene. The extractability can be explained on the basis of formation of 1∶1∶2 ($$metal:HPMPBH:SC\bar N/\bar N_3 $$) ternary species which are hydrophobic in nature. The methods based on these sensitive colour reactions are fairly selective.
