Vapour-liquid equilibrium in the butyl alcohol -n-decane system at 85, 100 and 115°C

Abstract Vapour-liquid equilibrium was measured isothermally in the butyl alcohol - decane system at 85, 100, and 115°C. At two lower temperatures the system exhibits azeotropic behaviour. The densities of liquid mixtures were determined at 25 °C. The data were correlated using the Margules, Wilson, and NRTL equations within the accuracy of experimental errors.

Vapour—liquid equilibria in the heptane—2-pentanol and heptane—2-methyl-1-butanol systems at 75, 85 and 95°C

Abstract Vapour—liquid equilibria were measured isothermally in the heptane—2-pentanol and in the heptane—2-methyl-1-butanol systems at 75, 85 and 95°C. Both the systems exhibit azeotropic behaviour. The densities of the liquid mixtures were determined at 25°C. The data were correlated using the Margules, Wilson and NRTL equations within the accuracy of experimental error.

Vapour—liquid equilibria in the heptane - 3-pentanol and heptane - 2-methyl-2-butanol systems at constant temperature

Abstract Vapour—liquid equilibria were measured isothermally in the heptane - 3-pentanol system at 75, 85, and 95 °C and in the heptane - 2-methyl-2-butanol system at 55, 65, 75 °C. Both the systems exhibit azeotropic behaviour. The densities of liquid mixtures were determined at 25 °C. The data were correlated using the Margules, Wilson, and NRTL equations within the accuracy of experimental errors.
