Proton transfer equilibria between m-substituted benzoic acids and the carbinol base of crystal violet in apolar aprotic solvents: A comparison between toluene-phase and aqueous-phase strengths of the acids

Abstract

A detailed study on proton transfer equilibria between twelve m-substituted benzoic acids and the carbinol base of crystal violet, the reference base, in toluene at 20°C and 28°C shows that toluene-phase strengths of the acids as compared to their aqueous-phase acidities are more than 4.5 times sensitive to the substituent's structure effects.
