The thermodynamic functions ACP, , ASí;, and AG£ are presented as functions of temperature over the entire composition range for three binary liquid systems. The pressure dependency of AH, AS£, and AG£ is determined from measurements of AV.1 HE PURPOSE of this paper is to present an extensive correlation of thermodynamic data for the binary liquid systems: ethanol-toluene, 1-propanol-rc-heptane, and 2-propanol-n-heptane. The results presented provide data over a considerable temperature range on the excess heat capacities, enthalpies, entropies, Gibbs free energies, and volumes of three highly nonideal alcohol-hydrocarbon solutions.
