High-precision micro-combustion calorimetry of anthracene

Abstract A high-precision micro-combustion calorimeter was developed. Details of the calorimeter are described. The energy equivalent of the calorimeter and the standard deviation of the mean were determined to be (67.8330  ±  0.0024) J · K  − 1 after calibration with thermochemical standard benzoic acid (five experiments). The standard enthalpy of combustion of anthracene was determined to be  − (7065.0  ±  1.1) kJmol  − 1 .
