This work is an extension of Yin's work studying the diffusion of Na ion in the PbCl2-NaCl system, but at more dilute compositions of NaCl.

Since only one example of an asymmetric synthesis which involved an intermediate containing an optically active ligand has been reported, two questions immediately arise: "Is this type of asymmetric synthesis an isolated example, or is it a stepping stone toward a generalized trend for Co (III) which may be extended to include levo rotatory, as well as dextro rotatory molecules?" In addition, asymmetric synthesis affords a new avenue for synthesizing resolved neutral complexes.

The object of this thesis is to establish the diffusion coefficient of Na ion in PbCl2-NaCl mixtures and to compare its relationship to the other species.

In the course of attempting to prepare 3,6-bis(hydroxy-methyl)-s-tetrazine via the reduction of 3,6-bis(carboxy)-s-tetrazine with lithium aluminum hydride, it became apparent that the tetrazine ring was cleaved.

A series of compounds were prepared by condensing 2,3-dimethyl-4,9-dioxo-1-(2-propyl)-naphth[2,3-d] imidazolium iodide with various aromatic aldehydes.

There is no available information in the literature on interaction between carboxyl hydrogen and ω-phenyl groups. Consequently, it was of interest to seek such interactions. Some form of interaction is evident from the study of the spectra of some phenylalkanoic acids and benzoyalkanoic acids.

A number of N-substituted-3-hydroxy-3-phenylphthal-imidines and some of the isomeric amides have been prepared in order to study changes in the infrared spectra of these compounds due to structural changes in the molecule, particularly with reference to a hydroxyl band at 3.0µ and a carbonyl band at 5.75µ.

The present work is a part of a systematic investigation of the frequency shifts in infrared absorption produced by changing to the anions carbonyl containing acidic compounds.

It is proposed in this thesis that the imperfect systems of Cram and of Schubert be combined with some modifications.

Since 1955 research has been conducted at North Texas State College on diffusion in molten salts. The object of this work was a continuation of the diffusion studies, specifically the diffusion of Pb210 and Cl36 in molten PbCl2-NaCl mixtures.

The turbidimetric method for the determination of lead ion developed in this work is not intended as a replacement for standard analytical procedures, but is presented solely as a laboratory exercise for courses in elementary instructional analysis.

As long ago as 1881, it was realized that a functional group of atoms in a molecule would cause an absorption band to appear at a particular frequency in the infrared spectrum of the molecule. In more recent years, the concept of characteristic group frequencies has become firmly established and has resulted in the present widespread use of infrared spectroscopy. There appear to have been relatively few studies of infrared absorption of organic acids as compared with their salts.

The experiment in this thesis involves a study of some 1-alkyl-1,2-dihydro-3-hydroxybenzo[g]quinoxaline-5,10-diones.

This thesis examines the optical properties of Christiansen filter systems.

An experiment was designed to study in the same animal any preferential absorption of a free fatty acid in the presence of a triglyceride of the same fatty acid. Rats were administered a mixture of free fatty acid and its triglyceride labeled with carbon-13 and carbon-14 respectively. Each isotope in the fed lipid and in the lipid recovered from the gastrointestinal tract was measured. The isotope effect, if any, was studied by administering a mixture of palmitic acid-1-C13 and palmitic acid-1-C14.

This study is concerned with the nature of the relatively unusual bonding which occurs in organolithium compounds as a direct result of the oligomerization and possible explanations for that bonding.

At the time this work was begun, there was some confusion about the technique necessary for the successful synthesis of organomagnesium compounds in hydrocarbon solvents and without solvents. It was decided to repeat the work of Bryce-Smith and Zakharkin. Thus began the study of the synthesis of organomagnesium compounds without solvents; the study of the reaction products of these organomagnesium compounds in hydrocarbons plus 2-butanone compared to the reaction products of the corresponding etheral Grignard reagent plus 2-butanone; and a preliminary study of the nature of these organomagnesium compounds in hydrocarbon solvents.

The study herein described involved the detection of pyridine N-oxide reductase activity in cell-free extracts of E. coli 9723, the determination of co-factors necessary for the enzymatic process, a study of the optimum conditions for enzyme catalysis, and a general characterization of the enzyme.

This study reported herein involves the synthesis and determination of certain biological activities of 4,5-dihydroxy-2-pyridinealanine and the synthesis of 3-pyridine-N-methylalanine.

The study reported herein concerns itself with the isolation of melaninless mutants of S. antibioticus, ATCC, 3723, and with the demonstration that at least one of the sites of mutation involves that of the enzyme, tyrosinase.

In many series of compounds, intensity of biological activity and chemical reactivity are proportional. Generally whenever a alkyl group replaces a reactive hydrogen atom, as would be the case for an N-substituted hydroxylamine as compared to hydroxylamine, the over-all biological activity of the resulting compound is lower than that of its nonalkylated analogue. Since toxicity and physiological activity are not proportional, this comparison can only suggest possible types of derivatives to prepare and test.

This thesis describes experiments made to test the corrosion inhibition of quaternary amines on steel.

This thesis will explore and study rhodium, a group VIII element that has rarely been studied.

The procedure of Takimoto, Denault, and Hotta was followed in order to prepare 4-amino-3-hydrazino-5-methyl-s-triazole hydrochloride (II) and its precursor, triamino-guanidine hydrochloride (I).
