Vapor-Liquid Equilibria for the Methane-Acetone and Ethylene-Acetone Systems at 25 and 50 °C

Vapor-liquid equilibria for the methane-acetone and ethylene-acetone systems at 25 and 50 °C and pressures up to 10 MPa have been measured by a vapor-liquid recirculation method. To check the reliability of the experimental procedure, vapor—liquid equilibria for the methane—n-hexane system at 37.8 °C and pressures up to 2 MPa have also been measured because this system has been studied by several Investigators. The thermodynamic consistency test has been applied to the data of this system. The Soave—Redlich—Kwong and Peng—Robinson equations of state have been used to correlate vapor—liquid equilibria for the methane-acetone and ethylene-acetone systems with the use of a temperature-dependent binary Interaction parameter.
