摘要
Determinations of heat capacities, C-p, and excess molar enthalpies, H-m(E), of the binary mixtures propylene carbonate + acetic or propionic acid were carried out at (285.15, 298.15 and 313.15)K using a Perkin-Elmer DSC differential scanning calorimeter and an LKB flow microcalorimeter. All experimental values are positive and increase with the increase of temperature. The data have been fitted to a simple cubic polynomial (for C-p) and the Redlich-Kister equation (for H-m(E)) to estimate the adjustable parameters and standard deviations of these systems. Results have been discussed in terms of molecular interactions and have been interpreted by an extended cell model. (C) 1997 Elsevier Science B.V.
