ABSTRACT

Adonitol was investigated by adiabatic calorimetry (AC), differential scanning calorimetry (DSC), thermogravity analysis (TGA) and oxygen-bomb combustion calorimetry. The heat capacity was precisely measured in the temperature range from 78 to 400 K by means of a small sample automated adiabatic calorimeter. The melting temperature, the molar enthalpy and entropy of fusion were determined to be T = 369.08 0.45 K, 36.42 0.18 kJ mol-1 and 98.68 0.49 J K-1 mol-1 respectively from the experimental Cp-T curve. The thermodynamic functions [ 0 0 T 298.15 H H ] and [ 0 0 T 298.15 S S ], were derived from the heat capacity data with an interval of 5 K. The standard molar enthalpy of combustion and formation of the compound have been determined to be 0 5 12 5 ( , ) c m H C H O cr = (-2562.4 +- 1.3) kJ mol-1 and 0 5 12 5 ( , ) f m H C H O cr = (-1120.1 +- 1.5) kJ mol-1 respectively by means of a precision oxygen-bomb combustion calorimeter at T = 298.15 K. The thermostablility of the compound was further studied by DSC and TGA measurements.
