VAPOR-LIQUID EQUILIBRIUM DATA OF CHLOROFORM-ETHANOL MIXTURES INSIDE POLAR AND NONPOLAR POROUS PLATES

Vapor-liquid equilibrium (VLE) data of chloroform-ethanol mixtures at different temperatures were experimentally measured in 3 different macroporous plates: a 13.5-μm pore diameter, sintered, stainless-steel plate; a 30-μm pore diameter, porous, carbon plate; and a 30-μm pore diameter, porous, Teflon plate. The experimental results showed that the VLE of this system in the stainless steel plate was dramatically altered and the azeotropic point was eliminated. However, the effect of the porous Teflon plate or porous carbon plate on the VLE of this system was insignificant. The VLE for the studied system was predicted through the theory of Abu Al-Rub and Datta and gave a good agreement with the experimental data.
