Notizen:
Apparent pK-values have been determined for 56 aromatic acids in the solvent system methylcellosolve (80 wt.- %)/water (20 wt.- %) with a previously described fully automatic titration apparatus. The validity of the Hammett equation was tested and found to express the experimental data with a deviation comparable with data for aqueous systems. Reaction constants ϱ are given for the apparent pK-values of phenols, benzoic acids, salicylic acids and benzene-sulfonanilides in the solvent system mentioned. The additivity of the effects of aromatic suhstituents on the apparent pK-values was tested and found to be comparable with the data for pK-values measured in aqueous media.
