The experimental data for �� (relative permittivities) and n (refractive indices), were measured for mixtures of 2-butanone (BN) (CH3COCH2CH3) with dichloromethane (����2����2), 1,2-dichIoroethane (CH2Cl.CH2Cl) and tetrachloroethene (CCl2CCl2) at the temperature 308.15 K. The values of ∆�� which represent the departures of the �� for the mixtures from the quantities occuring from the law achieved from mole fraction mixture, have been obtained. Calculated values of ∆�� shows positive sign for BN with CH2Cl2 and CH2Cl.CH2Cl, whereas it is negative in the case of BN with CCl2CCl2. With the help of the values of �� and n, the Kirkwood correlation parameter, g, have been calculated for mixtures of BN with CH2Cl2 and CH2Cl.CH2Cl. The values of g indicate that BN forms intermolecular complexes with these compounds. The Equilibrium constant Kf, for the creation of complexes (1:1) of BN with CH2Cl.CH2Cl and CH2Cl2, have also been obtained with the experimental data for ��.
