Influence of temperature and solvent viscosity on the rate of the proton-transfer reaction between 2,4-dinitrophenol and tri-n-butylamine
A microwave-pulse temperature-jump technique has been used to study the proton-transfer reaction between 2,4-dinitrophenol and tri-n-butylamine in a number of solvents. The effect of solvent viscosity of the rate constant at room temperature indicates that diffusion processes influence the reaction. From a study of the reaction in chlorobenzene over the temperature range +38 to –14°, the apparent activation energy for the forward reaction is –3.5 kJ mol–1. Possible reasons for the inadequacy of the Stokes-Einstein equation in the present systems are discussed.
