Thermophysical Property Measurement on Chemically Reacting Systems-a Case Study.

This short paper describes several experimental approaches for dealing with chemical reactions or decomposition which can occur when making thermophysical property measurements at high temperature and high pressure. The associated equipment was designed and built to allow thermophysical property data to be cast in a more realistic perspective by taking explicit account of chemical changes which may occur during an experiment. As an example of these methods, the measurements on the methanol system are discussed in detail.
