Abstract
The specific heat of 4,4'-dichlorobenzophenone has been measured by Adiabatic Calorimetry from 90 K to room temperature. As expected, two first order phase transitions were found at T 1 = 187 K and T 2 = 192 K, showing a noticeable thermal hysteresis of about 9°C, together with some thermal history effects. By means of a useful deconvolution of the specific heat curve, the values for the phase transition thermodynamic functions were obtained: j H 1 = 39.6 J/mol, j S 1 = 0.21 J/mol.K. j H 2 = 467 J/mol, and j S 2 = 2.41 J/mol.K.
