ABSTRACT

Isobaric heat capacities in the liquid and solid phases of chloroanilines and chloronitrobenzenes were measured by using a highly sensitive Tian-Calvet differential scanning calorimeter in the temperature range from 270 K to 350 K. For some of the studied compounds, temperature and enthalpy of fusion were also determined. Data on liquid heat capacities obtained in this work, were merged with available literature data, critically assessed, and correlated as a function of temperature.
