Vapor-liquid Equilibria for a Methanol-Toluene System: High Vapor Concentration or Methanol

Abstract

The vapor-liquid equilibria of a two component organic solvent was investigated experimentally. The vapor-liquid equilibria data for the ethylacetate-toluene system was in good agreement with the calculated values by Raoult's law. But in the methanol-toluene system, the vapor concentration of methanol was higher than that of the calculated ones. As vapor-liquid equilibria depend on the combination of organic solvent, and as vapor concentration is not always in good agreement with the calculated values, the measurement of solvent in its vapor phase is considered to be quite important to evaluate the human effect of mixed organic solvent.
