Title: Determination of Adsorption enthalpies and entropies of Inorganic Halides by Temperature Programmed Gas Chromatography
Author: Bachmann, K.
Rudolph, J.
Abstract: The possibilities of using temperature-programmed gas-solid chromatography·
for the determination ofadsorption enthalpies and entropies of inorganic chlorides are
investigated. This method is suitable, if data oflimited accuracy are acceptable, whereas
for more precise data isothermal gas chromatography is recommended. The advantage
of temperature-programmed experiments is that simultaneous investigations
can be made ofcompounds with very different volatilities. The results of these investigations
support the picture of "surface complexes" bet\veen the adsorbed molecules
(metal halides or oxyhalides, e.g., ReCls _ SnCl.s, PoCl.s. etc.) and the adsorbent (alkali
metal halides. SiO.!).
