Apparent molar volumes V-phi and apparent molar heat capacities C-p,C-phi have been determined for dilute aqueous solutions of ethanol, 1-propanol, and 2-propanol at temperatures from 278.15 K to 393.15 K and at the pressure 0.35 MPa. The molalities investigated ranged from 0.05 mol . kg(-1) to 1.0mol . kg(-1). We used a vibrating tube densimeter (DMA 512P, Anton PAAR, Austria) to determine the densities and volumetric properties. Heat capacities were obtained using a twin fixed-cell, power-compensation, differential-output, temperature-scanning calorimeter (NanoDSC 6100, Calorimetry Sciences Corporation, American Fork, UT, USA). The results were fit by regression to equations that describe the surfaces (V-phi, T, m) and (C-p,C-phi, T, m). Infinite dilution partial molar volumes V-2(0) and heat capacities C-p,2(0) were obtained over the range of temperatures by extrapolation of these surfaces to m = 0 mol . kg(-1).
