RESUMO

This work is concerned with the design, construction and test of a liquid phase and condensed vapor phase recirculation ebuliometer for determining vapor-liquid equi1ibrium of miscible and non reactant mixtures in the range of pressures between 100 and 1000 mmHg and in the range of temperatures between 300 ºC and 2000 ºC. The apparatus was successfully tested with a toluene-ciclohexane mixture at 760.00 mmHg , obtaining molar fractions with a maximum uncertainty of 8% relative to the Delzenne (9.A) values in the range of low and middle molar fractions. It has been also determined vapor liquid equilibrium data for ethanol-ethyleneglicol mixtures at 499.65 mmHg and 756.79 mmHg. From these data the dependence of the ethanol and ethylenoglicol activity coefficients with temperature and composition were calculated.
