Abstract
There are a number of substances used to calibrate various instruments with benzoic acid being an IUPAC recommended calibration material. It has gained recognition as a reference material because it exhibits an “ideal” behavior. Hence, benzoic acid is often used to aid in determining the enthalpy of sublimation values for various organic substances. In this study, the thermal behavior of benzoic acid is observed from a simultaneous thermogravimetry–differential thermal analysis (TG–DTA) unit. A series of tests under various experimental conditions is performed, and the results allow for the determination of the enthalpy of sublimation values for benzoic acid. The purpose of this study is to investigate the influence of experimental parameters, such as sample preparation procedures, heating rates, atmospheric conditions, and gas flow rates, on the calculated enthalpy of sublimation values. Enthalpy of vaporization for benzoic acid was also calculated.
