Liquid-liquid Equilibria of the System Acetic acid+Water+Tetrachloroethylene and Acetic acid + Water +Carbon tetrachloride

Abstract

Solubility curve and tie-lines were determined for the systems acetic acid+water+tetrachloroethylene and acetic acid+water+carbon tetrachloride at 25°C.The concentration of acetic acid at plait point was obtained from extranolation of the following correlation line, log χw vs.(ye-xe)/χw where xw is acetic acid concentration (wt. fraction) in organic layer and yw is acid concentration (wt. fraction) in water layer.
The data for lower concentration region were well correlated by Hirata's plots log yw/(1-ye) vs. log χw/(1-χw) For the acetic acid+water+chlorinated hydrocarbon syst ems. cloudy states did not appeared and phases were separated below nearly 20 wt % or above nearly 80 wt % of c hlorinated hydrocarbons, perhaps, due to the difference o f densities and interfacial tension of water- and organic p hases.
