An Apparatus for High-Pressure Thermogravimetry.

Abstract

Construction and operation of a high-pressure thermobalance usable to 300 psig and a temperature of 350C is described. A modified, commercially available balance mechanism and associated circuitry provide an apparatus that is easily constructed and has satisfactory performance characteristics. Thermograms are presented to show typical operation and performance of the apparatus, using aniline to demonstrate retardation of evaporation and copper sulfate pentahydrate to show relatively unchanged decomposition rates with increased pressure.
