The Reaction Of Sodium Iodide In Acetone With Halogenated Epoxides -- A Mechanism Study, Thomas E. Breuer

Masters Theses

"l-bromo-2,3-epoxybutane reacted with sodium iodide in acetone to give 3-iodo-l,2-epoxybutane in 70.1 per cent yield. 3-bromo-l,2-epoxybutane produced l-iodo-2,3-epoxybutane in 69.9 per cent yield when it was allowed to react with a solution of sodium iodide in acetone. No other product could be isolated after either reaction, although it is possible that another compound may have been produced in very small amounts. The iodoepoxides were oxidized to the corresponding α-iodoacid in approximately ninety per cent yield by silver oxide"--Summary, page 40.

Permeation Of Water Vapor Through Linear Polymer Films, Mohammed S. Rifai

Masters Theses

"Film formation from thermoplastic resin solutions Is Influenced by secondary intermolecular forces. Consider what may happen when organic coatings change from a liquid to a solid state. In the liquid state it is logical to consider the linear polymer molecules as agglomerates being dispersed in the volatile component rather than being present In solution. These molecular agglomerates are referred to as micelles. They have various degrees of orientation depending on the extent and the location of dipole forces in both polymer and solvent molecules.

When a coating is applied the solvent starts to evaporate and the micelles are driven closer …

The Anodic Dissolution Of Zinc In Aqueous Solutions, Glenn E. Stoner

Masters Theses

"The increasing demand for protective metals as coatings and non-corrosive alloys has stimulated extensive research on the fundamental behavior of metals in corrosive media.

One of the problems still unsolved is the nature of the mechanism of the anodic dissolution of metals like zinc, magnesium, beryllium, cadmium, and aluminum in aqueous salt solutions. Several schools of investigators have proposed different and opposing theories to explain the discrepancies which often arise between coulometric data and the weight loss of metal electrodes in certain salt solutions.

The purpose of this investigation was to obtain experimental data for the anodic dissolution of zinc …
