| Abstract: | Experimental determination of VLE data under constant liquid composition (isoplethic VLE data )by double circulation method was studied. By use of a new type double circulation ebulliometer, Isoplethic VLE data were determined under 15 different concentrations for the system ethanol-n-hexane in a temperature range from 298K to 331K. Isothermal VLE. excess free enthalpy, and differential heat of vaporization are calculated from 298. 15K to 328. 15K. |
