Abstract:  Ionization constants of some 2-(2-hydroxy-5-X-phenyl)benzotriazoles were measured by the ultraviolet spectrophotometric method. A linear cor­relation was found between the ionization constant values and σp constants of substituents X (ϱ= —2.6) and also between the wavenumber of the stretching vibration of the OH bond and the pKa values (ϱ= +41.1).
