Abstract  

A micro-combustion calorimeter was developed. The small energy equivalent (ca. 68 JK–1) of this calorimeter makes it possible to measure combustion energies of very small samples. The energy equivalent was determined by burning 2 mg of benzoic acid. The standard deviation of the mean energy equivalent was reduced to 0.014% in 5 experiments. The standard massic energy of combustion of salicylic acid and the standard deviation of the mean were determined to be –21871±5 J g–1, which agrees well with the literature values. The standard molar enthalpy of formation of salicylic acid was derived as –591.2±1.7 kJ mol–1.
