The densities of supercritical Con-tetrahydrofuran (cosolvent) binary mixture were measured at temperatures in range of 308.15 to 323.15 K and at pressure up to 16.5 MPa. The concentrations of tetrahydrofuran were from 0 to 0.57 mol/L. The partial molar volume of tetrahydrofuran was calculated based

Excess molar volumes were determined over the whole composition range for (dimethyl carbonate, or diethyl carbonate + n-heptane) at the temperatures (278.15, 288.15, 298.15, and 308.15) K, and at atmospheric pressure with a vibrating-tube densimeter. In addition, a differential scanning calorimeter
## Abstract The molar volumes of mixtures of perdeuteriated and protiated heptane have been measured between β10Β° and 40Β° and expressed as a second order polynomial of the weight fraction. The difference in molar volumes of about 0.4 ml/mol decreases with temperature. The possibility of using the d
The results of excess molar volumes for the ternary mixture N, N-dimethylformamide Ε½ . 4 Ε½ . Ε½ DMF q ethanol q water , and for the binary constituents DMF q water , DMF q . Ε½ . ethanol , and ethanol q water at T s 298.15 K were reported. Several empirical expressions were used to predict and correla
Measurements of the excess molar enthalpies H E m as a function of pressure and temperature have now been completed for all of the binary mixtures of ethane, propane, and butane with methanol, ethanol, propan-1-ol, and butan-1-ol. Excess molar volumes V E m were also obtained for selected systems. T
