Abstract

AcknowledgmentThe authors thank M. J. Calhoun for the GLC analysis of the ternary mixtures and also I. A. Wolff and N. C. Aceto of the Eastern Regional Research Center and R. E. White of Villanova University for their mutual cooperation in arranging for this work to be accomplished. NomenclatureT = temperature, K VP = vapor pressure, mm Hg X = liquid mole fraction Y = vapor mole fraction a, 0, 6 = constants in vapor-pressure equations y = activity coefficient T = total pressure, mm Hg Subscripts i = indefinite component number j = indefinite component number 1 = acetone 2 = isopropenyl acetate 3 = acetic anhydride Literature CRed(1) Redlich, O., Kister, A. T., I&. Eng. Work taken from a master's thesis on file at Villanova University. Use of a company or product name does not imply approval or recommendation to the exclusion of others which may also be suitable.The acid dissociation constants of a homologous series of nine I( 2-pyrldyl)-2-alkanones were determined by potentiometric titration. These pK,'s correlated with the Taft polar constituent constants (a*) for the ketones.
