SALT EFFECT ON VAPOR-LIQUID-EQUILIBRIUM OF METHYL TERT-BUTYL ETHER + METHANOL AT 298.15-K

Isothermal vapor-liquid equilibrium data were determined at 298.15 K for the systems methyl tert-butyl ether (MTBE) + methanol with Ca(NO3)2, LiCl, and LiBr, by using a saturation method. The vapor pressures of methanol saturated with these salts have been measured by a vapor pressure osmometry method. The experimental data have been satisfactorily fitted by using four activity coefficient models usually employed for systems without salt. The thermodynamic consistency was checked by the Rediich-Kister consistency test. © 1990, American Chemical Society. All rights reserved.
