ABSTRACT

Isothermal vapor-liquid equilibrium was measured for 2-propanol + 1,1-diethoxyethane at 353 K and ethyl ethanoate + 1,1-diethoxyethane at 348 K and 2-propanone + 1,1-diethoxyethane at 328 K with a circulation still. The liquid and condensed vapor phase samples were analyzed by a gas chromatograph. The experimental data was correlated with the Wilson and NRTL activity coefficient models. Experimental results and the fitted model were also compared with the predictive coefficient model Original UNIFAC.
