Dissertation/Thesis Abstract

Structure and Thermodynamic of Halogen Hydrates
by Wang, Qian, M.S., University of California, Irvine, 2013, 34; 1535376
Abstract (Summary)

So far to our knowledge, the bromine-xenon double clathrate hydrate has not yet been completely studied. In recent research in Janda lab at UC Irvine, we obtained the thermodynamic properties and structure of bromine-xenon double clathrate by applying UV-Vis spectroscopy and determining the total vapor pressure of the clathrate. In both of the TS-I and CS-II structures, bromine could only stay in the bigger size cages, while introducing xenon as a helper gas to occupy the smaller cages. Based on this concept, we hypothesize that the bromine-xenon double clathrate has the TS-I structure type below 273K, and the CS-II structure type above this temperature. Also we calculated the enthalpy of dissociation of the TS-I bromine-xenon double clathrate as 12.305±0.170kJ/mol/K, and the CS-II clathrate as 16.574±0.143 kJ/mol/K.
