The Synthesis And Physical Properties Of Several Aromatic Fluorides, Charles J. Basso

Bachelors’ Theses

Since the advent of the Manhattan Project, more attention is being focused on fluorine compounds. Most of the inorganic fluorides are well known and are being used daily in industry. However, the realm of organic fluorides has not been investi­gated much up until recently, mainly because of the lack of safe and efficient fluorination reactions. Only within the last twenty-five years have reliable, indirect methods of fluorination been developed.

The purpose of this thesis is to give an outline of the most important fluorination processes, speaking of laboratory scale operations. The author illustrates the synthesis of an· aromatic fluoride by …

A Scheme Of Analysis For The Ceric Rare Earths, Herschel Gordon Frye

University of the Pacific Theses and Dissertations

The elements numbered 57 to 71 have presented a problem in analytical chemistry unparalleled by that of any other group since their discovery over the span of the nineteenth century. The striking similarities in chemical behavior of the fifteen elements comprising this series have almost completely baffled analysts in every attack, and it is only with the increased use of those newer methods, best described as being of a strictly physical nature, that much real progress has been achieved. Where time-honored classical wet methods have failed rather disappointingly, newer methods based upon the use of the spectrograph and similar instruments …

Studies Of Some Reactions Of Quinoxaline, 2-Methyl-, And 2,3-Dimethylquinoxaline, Delos Edward Bown

Theses and Dissertations

Although many compounds have been prepared which contain the heterocyclic nucleus known as the quinoxaline nucleus, very little fundamental experimentation has been reported by way of expanding the chemistry of quinoxaline beyond the basic condensation reaction and its valuable use as a means of characterization, for example, the reaction of vicinal diketones with o-phenylenediamine. Also, no know effort has been made to assemble the chemistry of the quinoxalines into one paper for ready reference. Additional interest is concerned with the chemotherapeutic value of basically substituted quinoxalines^1; however, this aspect of the problem will not be discussed. The chemistry of quinoxaline …

The Influence Of Certain Factors In Urine On The Viscosity Of Gelatin, Leonard Driss

Bachelors’ Theses

After reading the Masters Thesis of Mr. Herman L. Karl, the writer became interested in this problem and then took · up the study of the proteolytic activity of normal urine. Mr. Karl worked on the urine of pregnant women. Using gela­tin as a substrate, he hoped to find a difference in prote­olytic activity between the urine of a woman pregnant with a male fetus and the urine of a woman pregnant with a female fetus. His results were not conclusive but suggested that the problem of proteolytic action of urine should be studied under normal conditions.

A Study Of Silica-Alumina Gels, Howard W. Bishop

Honors Theses

The general purpose of this investigation has been to obtain data concerning the preparation of and the time of set of a silica-alumina gel. Much work has been done here at Union College in studying the effects of temperature, hydrogen-ion concentration, presence and concentration of certain impurities, and other factors upon the time of set of a silica gel mixture. In these experiments, we used a silica gel mixture whose concentration of silica was the same as that used in these previous experiments, but we mixed with it enough alumina to form a final silica-alumina gel mixture whose mol ratio …

The Alkylation Of Dimethylaniline With Ethylene Glycol Sulfite, John R. Draves

Honors Theses

The alkylation of ter.-amines with alkylchlorosulfinates and alkylsulfites has been of interest in producing various betaine salts. Most of the work reported in the literature had been with ter.-aliphatic amines, amino acids, pyridine, straight-chain sulfites, and chlorosulfinates. No work has been reported on the alkylation of ter.-aromatic amines with cyclic sulfites and the betaine salts produced. The purpose of this investigation was to isolate and characterize the betaine salt produced by the alkylation of a ter.-aromatic amine with a cyclic sulfite. The reaction chosen was that between dimethylaniline and ethylene glycol sulfite.

The Synthesis And Physical Properties Of A Few Unsymmetrically Substituted Ethanes, Gerald R. Aldrich

Bachelors’ Theses

The writer's interest was aroused in the synthesis of organic fluorides while taking a course in Organic Preparations. The fact that fluorine chemistry was something relatively recent made the topic especially appealing. While the chloro, bromo, and iodo derivatives of most of the homologous series had been prepared, many of the fluorine compounds had not. Previous research had disclosed the asymmetrical diaryl ethanes possessed peculiar properties - to mention one, fluorescence. It was proposed that a few of the asymmetrical diaryl ethanes having fluorine and chlorine substituted on the ring in various positions with respect to one another be prepared …

Geology And Geological Structure Of The Alberta And Saskatchewan Plains, William E. Topley

Bachelors Theses and Reports, 1928 - 1970

Alberta, responsible for ninety per cent of Canada's output, had, by 1947 entered into her fifth year of production decline. Only ten per cent of Canada's oil requirements were secured from home fields. Ninety per cent had to be imported, mainly from the United States. How long could imports be maintained on present levels? During the year, the United States had started rationing; in one sector of its domain. Would this become general? If so, what was the answer for Canada?

The Identification Of Various Alkyl Halides Through Formation Of Quaternary Ammonium Salts, John L. Canning

Bachelors’ Theses

Within the field of the characterization of organic compounds the preparation of suitable derivatives of the compound to be identified is the final process of the laboratory analysis. When the unknown is of such chemical nature that the preparation of derivatives is difficult or impossible the identification is not too satisfactory. This is often the case when the unknown is an alkyl halide. At present the identification of many of these compounds depends exclusively upon an examination of the physical constants.

It is the purpose of this paper to investigate the possibility of preparing quaternary ammonium compounds by treating the …

An Investigation Of Phosphate Adsorption By The Clays Montmorillonite And Kaolinite /|Cby Gordon Richard Bradford, G. R. Bradford

Theses and Dissertations

Clay minerals have widespread application in industry and play an important role in plant life (2, 17). It is the adsorptive capacity of clay which determines largely its importance to man (2). The purpose of this investigation is to interpret the mechanism of adsorption of the phosphate anion by the two clay minerals montmorillonite and kaolinite. This particular system was singled out for two reasons: 1. It has agricultural significance. 2. It is believed that if the particular phosphate adsorption mechanism is understood it will aid in an understanding of many other adsorption phenomena associated with clay.

Physical Properties Of Ellis County Adobe, William G. Read

Master's Theses

Houses made of soil have been built for centuries, but until recently the trend had been away from soil to some other building material. Now, however, adobe is again beginning to be recognized as a satisfactory, reliable building material for our time. Recently, especially in the southwestern part of the United States, a surprising number of dwellers have turned again to earth for their building material. They are following in the footsteps of the early settlers, who constructed many missions and other buildings from sun-dried earth. Many of these buildings, although aged, are still in use or may be viewed …

Determination Of The Proper Mixtures Of Ellis County Soils For Adobe Construction, Buster W. Read

Master's Theses

The purpose of this investigation was to determine whether the soils of Ellis County could be used to form waterproof soil blocks that might be used for construction. In the investigation eight soils found in the county were employed and several stabilizers added to each in varying amounts to determine if the specific soils could be rendered waterproof. Several types of paint finishes were tested. The work was divided into three main parts: (1) Survey of Ellis County Soils; (2) Selection of soil material with respect to shrinkage; and (3) Treatment of soils with respect to waterproofing.

Manganese Oxide Deposits Near Butte And Development Since 1942, Emmett M. Gilmore

Bachelors Theses and Reports, 1928 - 1970

Concentration Of Manganese Dioxide From Philipsburg, Montana, W. M. Mcauliffe

Bachelors Theses and Reports, 1928 - 1970

Imports of manganese ore probably supply a major proportion of the needs of the United States. Domestic production is reported to be higher than pre-war levels, but does not equal that of the peak production year of 1943. In 1946, the Anaconda Copper Mining Company ac­counted for 90 percent of the total shipments of mangan­ese nodules, and this company is the largest producer of domestic metallurgical ore in the United States.
