Comparison of vapor pressure data for some highly polar substances with values calculated from the extended corresponding-states principl (⋄) Water; (□) Ammonia; (Δ) Acetic acid; (*) Methanol; (◯) Acetonitrile; (•) Diethyl ether; (+) Acetone; (♦) Decane. [Adapted from Xiang ...
1.The pressure exerted by water vapor in the atmosphere. 2.The pressure exerted by a vapor on the solid or liquid phase with which it is in equilibrium. At pressures lower than the vapor pressure, atoms or molecules of the liquid or solid being vaporized can escape from the surface of th...
Molar excess Gibbs free energies of mixtures of methanol and ethanol with n-decanol were obtained from static vapor pressure measurements over the temperature range 20–50 °C. The molar excess entropies of the system methanol–decanol are predominantly negative at 25 °C; those of ethanol–...
摘要: Total pressure measurements for ammonia + methanol were made at 10 °C and 20 °C. The liquid and vapor compositions were derived by iteration from the material balance and the Martin−Hou equation of state.DOI: 10.1021/je980244n 被引量: 13 ...
Answer to: The vapor pressure of water at 100.0 degrees C is: (a) 175 torr. (b) 85 torr. (c) 760 torr. (d) 1 torr. (e) More information is needed...

Vapour-liquid equilibrium data at 760 mmHg pressure for the binary systems -hexane-isopropanol and benzene-isopropanol, and the ternary system n-hexane-benzene-isopropanol, are presented. The binary data were tested for thermodynamic con... S Govindaswamy,A Andiappan,S Lakshmanan - 《Journal of ...
A vapor-liquid equilibrium cell of a new design to withstand high temperature, high pressure and corrosive fluids is constructed. Vapor-liquid equilibrium is measured for mixtures of 1-propanol and p-xylene at 160.0 and 221.1°C at pressures to 26 bar. The VLE data are correlated with Wong ...
