Thesis submitted to Univ. of New Mexico, Albuquerque. I. The work described is concerned with the kinetics of an S/sub N/2 reaction, the isotopic exchange reaction between iodide ions and p-nitrobenzyl iodide, carried out in an aprotic solvent, acetone, in the presence of various substituted phenols and anisole. This reaction was carried out at concentrations of potassium iodide low enough to ensure the absence of ion pairs. The tendency of substituted phenols to reduce the observed second-order rate constant was correlated with the ability of each compound to form a hydrogen bond with the iodide ion. As expected, the anisole had no noticeable effect on the rate. The experimental data were analyzed by a method which makes allowances for the presence of small and constant amounts of hydroxylic impurities. H. The Adsorptive and Radiocolloidal Properties of Carrier-Free Silver. This section deals primarily with the removal of carrier-free silver-110m from dilute nitric acid and aqueous solutions of miscellaneous common reagents by adsorption on Pyrex glass. Adsorption is believed to occur via a relatively rapid cation-exchange process followed by a slow diffusion step. Radiocolloids were detected by high-speed centrifugation in 0.0001 molar please delete the above abstract no. 5207
