Influence of Styren Addition on the Ionization-Dissociation Equilibrium of Trityl Halides in Methylene DichlorideThe ionization-dissociation equilibrium in solutions of trityl halides in methylene dichloride is effected by the addition of π-donors as a function of the temperature. The intensity of the trityl absorption of trityl fluoride and trityl chloride is decreased as it can be shown by u.v.-spectroscopy. The trityl absorption of trityl bromide solutions in methylene dichloride is very sensitive towards temperature changes. Measurements of the equilibrium constants for the ionization - dissociation-equilibrium, when styrene is added to the solution, indicate a specific solvation effect by the styrene molecules, however, a stabilization of ion pairs by specific solvation due to styrene molecules does not occur.
