Pyridylazonaphthols (PANs) and pyridylazophenols (PAPs) as analytical reagents. Part IV. Formation of complexes with titanium(IV)
Abstract
The formation of complexes of titanium(IV) with PANs and PAPs has been investigated in order to ascertain the types of complexes that are formed and to elucidate the optical and stability constants of such complexes. The competing effect of hydrolysis on these reactions has also been considered. The reaction with 2-(2-pyridylazo)-1-naphthol (o-α-PAN) has been examined in order to determine the analytical utility of this complex formation.
