| Abstract: | Solubility measurements of propene in water at atmospheric pressure and at thirteen temperatures in the range 293.15–323.15 K were carried out with a precision of 0.3%, using an apparatus based on the saturation method. The mole fractions, at a gas partial pressure of 101.325 kPa, were fitted to a Clarke–Glew–Weiss equation, which was used to calculate the standard molar Gibbs energy, enthalpy, and entropy changes for the process of transferring the propene molecules from the gaseous to the water phase. Solubility measurements of propene in the growth medium ofXanthobacter Py2 at 298.15, 303.15, and 308.15 K were also carried out at atmospheric pressure. These experimental data, expressed in Ostwald coefficients at the total pressure of 101.325 kPa, were about 2% lower than their water counterparts. |
