Rezumat:

The experimental densities of binary mixtures of cyclohexanone with 1,1,2,2-tetrachloroethane, 1,1,1-trichloroethane, trichloromethane, 1,2-dichloroethane, 1,3-dichloropropane, 1,4-dichlorobutane and 1-chlorobutane have been measured at T = (288.15, 298.15, 308.15, and 318.15) K and atmospheric pressure, over the whole composition range. From these results, excess molar volumes, VE, have been calculated and fitted to Redlich–Kister polynomial equation. The excess molar volumes are negative for the cyclohexanone + 1,1,2,2-tetrachloroethane, 1,1,1-trichloroethane, trichloromethane and 1-chlorobutane systems and positive for the other three systems, over the whole composition range and at all investigated temperatures. The variation of these properties with composition of the binary mixtures is discussed in terms of molecular interactions between components and structural effects.
