Thermodynamic functions for halogenated benzenes

Butler, Jeremy Bruford January 1967 (has links)
The availability of molecular structural and spectrographic data has enabled the calculation of the ideal gas thermodynamic functions [formula omitted] for thirty eight halogenated benzenes. The thermodynamic functions are given for temperatures between 273.15° K. and 1500° K., at one atmosphere. The contribution of the anharmonicity effect to the thermodynamic properties is discussed. Additionally, a method is described for making real gas corrections to the ideal gas thermodynamic functions, however, only over a limited range of pressure and temperature (15 atm. to 0.25 atm. 273.15° K. to 1000° K.). This method, based on the Berthelot equation of state, requires the critical temperature and pressure, which are summarised in this work for several of the halogenated benzenes. As an example of the method, the real gas thermodynamic functions for fluorobenzene are shown, at pressures between 10 atm. and 0.25 atm. Finally the thermal stability of the halogenated benzenes is discussed and the temperatures over which the ideal gas thermodynamic functions are applicable are indicated. / Applied Science, Faculty of / Chemical and Biological Engineering, Department of / Graduate

Desorption/Diffusion of Benzene After Simulated Ground Water Remediation

Bennett, Kathryn C. (Kathryn Condreay) 12 1900 (has links)
A study was undertaken to examine the desorption/ iffusion of benzene after simulated ground water remediation in aquifer material of differing carbon content using column experiments and comparing the results to batch experiments and adsorption empirical relationships. It was hypothesized that the organic carbon of the aquifer material will affect desorption/diffusion. Results from the column experiment indicated no significant difference in the increase benzene concentrations after remediation between aquifer materials of differing carbon content, however, a significant increase in benzene concentration was observed for all aquifer material. Fair agreement of retardation factors was observed between empirical relationships and batch and column experiments. However, the desorption phase of the batch experiment showed hysteresis and seemed to differ from the column experiment.
