Abstract

Isothermal phase equilibria for the system methanol-ethylene were measured at 25°C and 40°C by a static method. At each temperature, an invisible boundary in a high-pressure equilibrium region was found by gas chromatographic analysis. For studying the phase behavior of the methanol-ethylene system, the critical loci for the system were estimated by using the Soave-Redlich-Kwong equation of state. The calculation shows that an isothermal phase equilibrium of the methanol-ethylene system exhibits one to three critical points.
