Abstract
The dissociation of 4-(4-nitrophenylazo)-1-naphthol (azo dye) in pyridine was found to be accelerated by the addition of small amounts of quaternary ammonium compounds, R4N+X−. The apparent equilibrium constant of the azo dye was influenced enormously by the species of X−, but was little affected by the structures of R. The effect increased as the X− became more basic, ClO4−
