Kinetic Studies Of Ammonia-Oxygen Flames, David Emlyn Hughes

Graduate Dissertations and Theses

Since the early interest of Henry in burning ammonia with electric sparks, the literature of ammonia oxidation has been extensive. The major efforts have been industrially related and concern themselves with catalytic oxidation and its mechanism. The flame oxidation of ammonia has attracted more modest interest because of the relative poorness of ammonia as a fuel. Lunge, for example, found that an ammonia-air flame would hardly burn at room temperature and could be maintained only with constant heating. This dissertation concerns itself with the mechanism of the flame oxidation of ammonia and therefore the reactions that transform ammonia and oxygen …

Kinetics Of Alkali Metal Ion Self-Exchange On Polystyrene Sulfonate Resin In Dimethyl Sulfoxide-Water Media, Robert Clark Johnston

Graduate Dissertations and Theses

Rates of alkali metal cation self-diffusion in a polystyrene sulfonate ion exchange resin and in the external solution have been measured over a range of dimethyl sulfoxide (DMSO)-water mixtures from 0 to 70 mole % DMSO. Interpretation of results is simplified by the choice of this system which exhibits relatively constant resin swelling, fairly high dielectric constant and virtually no solvent preference over the entire composition range.

The self-diffusion coefficient of Na⁺ in the external solution shows a moderate decrease from 0 to about 40 mole % DMSO after which it tends to level off with increasing DMSO. In …
