Contribution à la détermination des propriétés thermodynamiques des chlorophénols dans l'eau et dans le 1-octanol

Abstract : The purpose of the present work is the study of the thermodynamic properties of phenol and chlorophenols in aqueous and 1-octanol solutions. Vapor liquid equilibria of diluted solution using a ebulliometric method, excess enthalpies of mixing with the SETARAM C80 and volumetric properties by the use of an Anton Paar densimeter were made. All these experimental studies were used to determine activity coefficients, excess partial enthalpy and partial molar volume, at high dilution of phenol and chlorophenols in water and 1-octanol. Results obtained show the existence of a strong molecular association between chlorophenols and 1-octanol and the high hydrophobicity of those compounds. Our experimental data were modelted using a modification of UNIFAC methods (Larsen et al., 1987 and Gmehling et al., 1993) based on correlation of some interaction parameters with physical descriptors used in LSER method (Kamlet et al., 1988)
