Price, Duncan M.; Volatilization, Evaporation & Vapor Pressure Studies using a Thermobalance. Proc. 28th North American Thermal Analysis Society Conference, October 4-6 (2000) Orlando, Florida, USA, pp. 216-221
There is considerable interest in performing volatilization and evaporation measurements by thermogravimetry. A quick and simple method for determining vapor pressure using a conventional thermobalance and standard sample holders has been developed. These yield meaningful thermodynamic parameters such as the enthalpies of sublimation and vaporization. Under favorable conditions the melting temperature and enthalpy of fusion of compounds can be obtained. This technique has been used for the study of dyes, UV absorbers and plasticizers. The use of modulated-temperature programs for such work is also described.
