The heat capacities at constant pressure of some alpha,omega-bromochloroalkanes (from C2 to C6) and alpha,omega-dibromoalkanes (from C2 to C12, without C7 and C10) were measured within the temperature range of (285.15 to 355.15) K. The measurements were performed by means of a Micro DSC III (Setaram) differential scanning calorimeter. The dependence of molar heat capacity on temperature and hydrocarbon chain length was described by the group additivity method. The densities of a,alpha,omega-bromochloroalkanes within the temperature range (288.15 to 318.15) K and their volumetric expansion coefficients at 298.15 K were also determined.
