The results of the density measurements for the pair systems containing nitromethane with 1,1,2,2-tetrachloroethane, 1,1,1-trichloroethane, chloroform, 1,2-dichloroethane, 1,3-dichloropropane, 1,4-dichlorobutane, 1-chlorobutane and 1-chloropentane at T = (298.15, 308.15, 318.15) K and atmospheric pressure, on entire compositional range are reported. The derived excess molar volumes, VE, are positive for the nitromethane + 1,1,1-trichloroethane, + 1,2-dichloroethane, + 1,3-dichloropropane, + 1,4-dichlorobutane, + 1-chlorobutane, + 1-chloropentane binary mixtures and they are negative for the other two systems: nitromethane + 1,1,2,2-tetrachloroethane, and + chloroform, on the entire compositional range and at all three studied temperatures. The excess molar volumes have been correlated with three parameters Redlich-Kister equation.
