The rate of unsteady-state evaporation of a stagnant layer of methanolwater, formic acidwater, ethanolisopropanol, methanolethanol, and methanolisopropanol binary solutions into an inert gas (helium or argon) is studied in a closed system. The ratio between the molecular weights of the components in a gasliquid system is shown to have a substantial effect on the process kinetics. For the first time, a synergetic interaction between the components during unsteady-state mass transfer is observed. The experimental data satisfactorily agree with the calculated results.
