Abstract: The molecular structures and the solute-solvent interaction play vital role in finding the correlation between the like and unlike molecules in a mixture. The systems CH2Cl2 + CS2, CH3OH + CCl4, CH3OH + C6H6 and CH3OH + CHCl3 have been investigated over the whole composition range. Statistical thermodynamics shows a way to calculate the partial molar qualities, isothermal compressibilities and interaction parameters through a few parameters like density, hard sphere diameter, temperature. The interaction is represented by Kirkwood-Buff parameters Gij, Gjj and Gii, representing the like- like and like-unlike molecular interactions. The partial molar volumes, partial vapour pressures and partial isothermal compressibilities have also been also calculated from statistical thermodynamics. The interaction parameters at different mole fractions are discussed and compared with other experimental results of partial vapour pressures.
