文摘

An isoperibolic combustion calorimeter developed to measure the enthalpy of combustion of organic compounds containing carbon, hydrogen, oxygen, and nitrogen atoms has been assembled, calibrated, and tested. The calorimeter was calibrated with benzoic acid NIST 39j, and the resulting energy equivalent was ε(calor) = (10116.8 ± 0.5) J K−1. Salicylic acid, 1,2,4-triazole, and acetanilide were used as test compounds. The main result is that all obtained values of the standard molar enthalpy of formation for the test compound are in agreement with the results available in the literature.
