The conditions in which 4-arylazo-phenols and 4-arylazo-anisoles have basic properties have been studied.We have also determined the equilibrium constants of the reactions between 4-arylazo-phenols or 4-arylazo-anisoles with perchloric acid in nitromethane, acetonitrile and acetic acid.Conclusions have been drawn from the influence of the nature of solvent and substituent at the benzene ring on equilibrium constant values.
