摘要：

The protonation of 19 derivatives of mono-and bis-azochromotropic acid has been studied and the protonation constants determined. The effect of the substituents is described by comparison with different zero" reagents. The relationship between the values of the protonation constants and the molar absorptivities of the protonated form of the reagents is discussed. © 1969."
