ABSTRACT
The heat capacity of Al(C11H19O2)3 was measured by adiabatic-shield calorimetry in the temperature range 6-320 K; no transition or thermal anomalies were found. The thermodynamic functions (entropy, enthalpy, and reduced Gibbs free energy) at 298.15 K have been calculated using the obtained experimental heat capacity data. The obtained standard values are as follows: C p,m = (882.3+-1.3) J mol-1 K-1, D0 298.15S m= J(980+-2) mol-1 K-1, D0 298.15H m= (145.1+-0.2) kJ mol-1, F m= (493.4+-1.7) J mol-1 K-1.
