Heat Capacity of 伪,蠅-Bromochloroalkanes and 伪,蠅-Dibromoalkanes: Their Dependence on the Hydrocarbon Chain Length and Temperature (285.15 to 355.15) K
文摘
The heat capacities at constant pressure of some 伪,蠅-bromochloroalkanes (from C2 to C6) and 伪,蠅-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 伪,蠅-bromochloroalkanes within the temperature range (288.15 to 318.15) K and their volumetric expansion coefficients at 298.15 K were also determined.
