چکیده:

New experimental data are reported for the thermodynamic investigation of the intermolecular halogenated compounds in non-polar solvent. Experimental data are reported of excess molar volumes, excess Permittivity and excess Gibb’s free energy (ΔG) of binary mixtures of Flourobenzene, Chlorobenzne,Bromobenzne ,4-Chlorobenzaldehyd , 4-flourobenzaldehyd in 1,4–dioxane at various concentrations at 298 K, 308 K and 318 K. The of mixing calculated using the experimental value of relative permittivity on the basis of Winkelmann–Quitzsch equation. The V E values were measured using a dilatometer and are positive over the entire mole fraction range for all the systems.
