The vapor-liquid equilibrium (P, T, x, y) for dimethyl ether and 2-methylpropane was measured at 280, 290, 300, 310, and 320 K by the dynamic method with recirculation of the vapor through the liquid phase. The composition was measured by a gas chromatograph connected "on-line" to the equilibrium cell. The response of a flame ionization detector was calibrated over a wide composition range using mixtures being prepared by mass. The experimental results were reduced by the Carnahan-Starling-De Santis equation of state assuming that its binary interaction parameter was temperature independent. The system is azeotropic with strong positive deviation from Raoult's law.

Abstract
The vapor-liquid equilibrium (P, T, x, y) for dimethyl ether and 2-methylpropane was measured at 280, 290, 300, 310, and 320 K by the dynamic method with recirculation of the vapor through the liquid phase. The composition was measured by a gas chromatograph connected "on-line" to the equilibrium cell. The response of a flame ionization detector was calibrated over a wide composition range using mixtures being prepared by mass. The experimental results were reduced by the Carnahan-Starling-De Santis equation of state assuming that its binary interaction parameter was temperature independent. The system is azeotropic with strong positive deviation from Raoult's law.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
