“…A comparison among the various K = K(T, X) equations proposed in the present work and in previous studies (10)(11)(12) for similar solvent systems has been made by considering the criteria of the smallest difference between calculated and experimental values, of the simplest equation, and of the applicability to the largest number of solvent systems. This comparison has suggested that, in general, quite acceptable agreement between calculated and experimental values is achieved, even if the same equation may be employed with better results for the present system and for the previously studied GlietIGliem one.…”

“…In previous papers, we have reported some studies about acid-base equilibria in ethane-1,2-diol (hereafter abbreviated ED) (Franchini et al, 1989) and 2-methoxyethanol (ME) (Preti et al, 1982); both the solvents are amphyprotic, potentially acidic media. They have been used as nonaqueous pure solvents, in their binary mixtures (Franchini et al, 1990) and in mixtures with water (Franchini et al, 1988;Marchetti et al, 1989). Now, we have in progress some investigations about amido-alcoholic solvent systems containing N,Ndimethylformamide (DMF), a quite dipolar protophylic, potentially basic solvent, and the above-mentioned ED and ME, in order to cover the largest variability range of nonthermodynamic properties.…”
