摘要:

The vapor pressure of Te over the Au–Te melts was measured in the 0.48 ⩽xTe⩽ 0.67 range with the help of a Knudsen cell apparatus combined with a varian–Mat mass–spectrometer.

摘要:

Water solubilities of paraffins have been estimated by the method of artificial neural nets. The method, using the normal boiling point and temperature as the input parameters could estimate the solubilities of 151 paraffins at the temperatures of 298 K and 372 K with an overall deviation of 3.4%, yielding superior results over those obtained by least squares.

摘要:

A gas chromatographic method for simple and accurate measurement of isothermal phase equilibrium studies has been proposed and applied to: aliphatic alcohol (methanol, ethanol and n-propanol)+aromatic hydrocarbon (benzene, toluene, o–xylene, p–xylene and ethylbenzene) binary mixtures. The present measurements on: benzene with methanol, ethanol and n-propanol and toluene with ethanol are in good agreement with the isothermal phase equilibrium data available in the literature.

摘要:

Experimental solubilities are reported for pyrene dissolved in six binary mixtures containing 2-methyl-1-pentanol with 1-propanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-1-propanol and 1-octanol at 26°C. Results of these measurements, along with previously published solubility data for pyrene in binary alcohol+alcohol solvent mixtures, are used to test the limitations and applications of expressions derived from Mobile Order theory and the Kretschmer-Wiebe association model. Alcohol-specific Mobile Order theory association constants are calculated from vapor-liquid equilibrium data for binary alkane+alcohol solvent mixtures, and used in the solubility predictions. For the 42 different systems considered, both models provided very accurate predictions of the pyrene solubilities, with an overall average absolute deviation between measured and calculated values being 2.0% and 1.6% for Mobile Order theory and the Kretschmer-Wiebe association model, respectively.
