Excess molar volumes of binary liquid Mixtures of cyclohexanone + dichloromethane, + trichloromethane, + 1,1,1-Trichloroethane and 1,2 Dichloroethane at 308.15 K

Excess molar volumes, Vm ^E, at T 308.15 K have been measured for binary liquid mixtures of cyclohexanone (C₆H₁₀O) + dichloromethane (CH₂CI₂), + trichloromethane (CHCL₃), + 1,1,1trichloroethane (CCl₃CH₃), and + l,2- dichloroethane (CH₂ClCH₂Cl). The values of Vm ^E have been fitted in appropriate equations using a least-squares method. V_m^E has been found to be negative throughout the entire range of composition for mixtures of C₆H₁₀O + CH₂Cl₂, + CHCl₃, and + CCl₃CH₃. For C₆H₁₀O + CH₂ClCH₂Cl, Vm ^E has been found to be positive at lower mole fractions of C₆H₁₀O, and negative at higher mole fractions. These results indicate presence of specific interactions between these components.
