A Study Of The Beneficiation Of Low-Grade Domestic Chromite, Darrell Edward Bodie

Bachelors Theses and Reports, 1928 - 1970

Chromite, a strategic mineral, is being consumed in ever increasing quantities in the United States today. Although the United States imports practically all of the chromite that is being consumed, it is gradually becoming necessary to exploit the low-grade deposits that are located within the United States, and also the low-grade deposits of Canada.

It is south of Cache Valley in which Logan, Utah, is located and north of Ogden Valley, east of the Wasatch Range near Ogden, Utah.

The Rendezvous Peak area is centrally located in a little known and critical area between the Logan Peak syncline in the Bear River Range and the more complex structures in the Wasatch …

Effect Of Bicarbonate Ion And Root Aeration On Lime-Induced Chlorosis, Willard L. Lindsay

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chlorosis in plants has been recognized as a devastating disease for over one-hundred and fifty years. It is easily recognized by a yellowing of the plant foilage and is associated with a reduced chlorophyll synthesis.

Chlorosis is found so frequently on calcareous soils that its cause is attributed at least in part to this soil factor. It is therefore referred to as lime-induced chlorosis. This type of chlorosis has become a serious problem, especially in many of the fruit-growing regions of Europe and the Western United States where the soils are calcareous. In Utah the disease is more destructive than …

The Reaction Of Some Sodium Salts Of Fatty Acids And Benzoic Acid With Α-Bromobenzyl Cyanide, Richard W. Perkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fife (4) and O'Shaughnessy (12) have made a series of di-esters by allowing the sodium salts of various fatty acids to react with ethyl monochloracetate according to the following equation:

RCO₂Na ≠ ClCH₂CO₂C₂H₅ ---------> RCO₂CH₂CO₂C₂H₅ ≠ NaCl .

The mechanism of the reaction appears to be ionic and to involve the attack of an RCO₂^- ion on the carbon atom to which the chlorine atom is attached. As the RCO₂^- approaches this carbon atom the chlorine atom moves …

The Benefication Of A Low-Grade, Montana Scheelite Ore, Walter G. Parker

Bachelors Theses and Reports, 1928 - 1970

The increasing importance of tungsten as an industrial metal and the recent discoveries of extensive deposits of low-grade tungsten ores in Montana led to the investigation which is reported in this paper. The purpose of this investigation was to determine if a saleable concentrate could be obtained from one of these low-grade, Montana scheelite ores.

A Petrographic Analysis Of The Basal Member Of The Kootenai Formation, Frank E. Coupal

Bachelors Theses and Reports, 1928 - 1970

The basal member of the Kootenai formation in south­western Montana is typically a fine to medium-grained "salt and pepper" sandstone and chert-pebble conglomerate. The section between Delpine, Montana, and Melrose, Montana, generally thickens and markedly coarsens to the West.

The Determination Of Chlorine In Alkyl Chlorobenzoates To Establish Their Identity And Purity, Clifford R. Berres

Bachelors’ Theses

Four years ago an investigation began at Marquette University with the purpose of determining the value of alkyl chlorobenzoates as derivatives for alcohols in characterization work. The outcome of this initial investigation was the preparation of thirty compounds previously unreported in the literature, namely, the methyl through decyl, nonyl excepted, ortho- and para-chlorobenzoates, and 2,4 and 3,4 dichlorobenzoates. The method of preparation and physical constants of these compounds were determined by Mr. Robert Johnson who presented a thesis on the "Preparation of Alkyl Chlorobenzoates and Their Application as Alcohol Derivatives" in June, 1949.

A continuance of this investigation was undertaken …

This 13 page thesis examines the preparation of heavy metal soaps from purified naphthenic acids.

An Azimuth-Stabililzed Balloon Platform, Alfred H. Spano

Physics & Astronomy ETDs

In the study of Zodiacal Light, an interesting task is the determination of the intensity and the position of this glow on the celestial sphere. The problem of photographing this phenomenon from the earth’s surface has been hampered generally by the inevitable presence of the atmosphere between the camera and the object. However, it is expected that at the height of some thirty kilometers above the earth, the atmospheric haze will be reduced enough so that pictures of the zodiacal region may be obtained without significant absorption. To accomplish this, it is necessary to keep the balloon-borne camera pointed in …

Paleontology And Stratigraphy Of The Carboniferous Rocks Of The Placitas Region, Northern Sandia Mountains, Sandoval County, New Mexico, Donald Francis Toomey

Earth and Planetary Sciences ETDs

A paleontologic and lithologic study of the Carboniferous rocks of the northern Sandia Mountains demonstrates that this predominantly marine sequence is divisible into several important series which are recognizable elsewhere.

The pre-Pennsylvanian rocks lack diagnostic fossils. However, correlation with a fossiliferous sequence in the southern Nacimiento Mountains, based on similar lithology and stratigraphic position, indicates a middle mississippian Meramec age for these rocks. The thickness ranges from 21 to 81 feet; they consist mainly of limestone associated with basal elastics. This sequence lies directly on Pre-Cambrian rocks. Nine sections have been measured and are shown geographically on three plates.

Oil Shales In Montana, Richard N. Miller

Bachelors Theses and Reports, 1928 - 1970

Montana has long been known to have very large resources of coal and oil, and undetermined amounts of oil shale. The reserves of coal and oil have been proven, in part, and have been produced commercially, but not much is known about the extent and apparent value of the oil shales. Under present .conditions, and according to standards set by the United States Bureau of Mines, the shales are not of commercial value. They are, however, a potentially valuable mineral resource, and portions of them will possibly be utilized, although not in the near future.

A Microcoulometric Study Of Adsorption On The Hydrogen Electrode, Ray Douglas Sothern

Master's Theses

Thie work was begun with the intention of studying the adsorption of organic compounds upon the hydrogen electrode. The fact that certain substances, even when present in extremely low concentration, will poison the electrode with which they are in contact shows clearly that these substances must be strongly adsorbed on the electrode surface. The problem or determining the amount absorbed at various concentration, temperatures, and pressures, however, required a method capable of detecting quantities of adsorbate in the ordor of 10^-11 moles.

Coloring Matter In Camillia Japonica Flowers, Robert James Stoner

University of the Pacific Theses and Dissertations

The coloring matter in flowers has been used for centuries as a dye. Early man did not know the chemical nature of these coloring matters. Recent investigations have shown that the dark pigments whereas the lighter pigments of flowers are in the anthoxanthin group of pigments. Both of these groups of pigments have a heterocyclic structure. A large number of these pigments have been isolated and identified.

The object of this research was to isolate and identity the coloring matter in the Camillia japonica (Belgian red) flowers. This was done by extracting the pigment with methanol and then crystallizing the …

The Effect Of Cross-Linkage On Internal Diffusion In Dowex-50 Ion Exchange Resin, John Paul Peterson Jr.

University of the Pacific Theses and Dissertations

As far back as the time of Aristotle sand filters were used to purify water. However it was not until the time of Thompson and Way (1848), two English agricultural chemists, that the idea of actual exchange of ions was proposed. Ion exchange has been investigated extensively, resulting in applications to softening of water, purification of sugar, separation of compounds, recovery of metals, many pharmaceutical separations and many others.

It has been proposed that the internal diffusion should be related to the internal structure of the ion exchange resin. The object of this research was to measure the internal diffusion …

Ultraviolet Absorption Spectra Of Quinoxaline And Some Of Its Derivatives, Fred Dale Huillet

Theses and Dissertations

A long term research program into the chemistry of quinoxalines has been instituted at Brigham Young University with the aim of preparing the vinylquinoxalines so that their 1,4-addition reactions might be studied. The literature of quinoxaline chemistry has been thoroughly reviewed and assembled. Methods of preparing 2-methyl- and 2,3-dimethylquinoxaline have been studied and improved but all attempts to prepare the vinylquinoxalines have been unsuccessful. In the course of these attempts several compounds of unknown structure were prepared. The purpose of this investigation is to study the spectra of various known quinoxaline derivatives and to attempt to identify the unknowns by …

Thiocyanate Complexes Of Osmium, Craig Albert Townsend Jr.

University of the Pacific Theses and Dissertations

Osmium is a hard grey brittle metal which scratches glass. It has a melting point of 2700[degree]C, and a specific gravity of 22.4, which is greater than any other known substance. The grey color of osmium resembles the grey color of iron and ruthenium. Osmium was discovered in 1803 by Tennant in the insoluble residue remaining after treating an alloy of the platinum metals with acid.

Osmium occurs in nature alloyed with the other metals of the platinum group. One type of alloy includes all six of the of the platinum metals, osmium, iridium, platinum, ruthernium, rhodium and palladium. Osmium …

The Urea Adducts Of Certain Esters Containing Twenty Carbons, Donald Eugene Johnson

University of the Pacific Theses and Dissertations

Urea has the interesting and unexpected property of forming solid complexes with many straight-chained organic compounds. So selective is the formation of these complexes with linear aliphatic compounds that it provides a means of separation form the analogous branched and cyclic compounds. Linear esters derived from normal saturated and unsaturated esters give adducts also but not to the same extent. Although many linear aliphatic compounds form adducts, the compounds so formed have varying degrees of stability depending on molecular weight, saturation and the shape of the molecule.

The purpose of this investigation is to determine the effect of the position …

A Petrographic And Chemical Study Of The Bevier Coal Seam, Philip John Clarke

Masters Theses

"Samples of coal were taken at three inch intervals vertically down the Bevier seam at three localities in Macon and Randolph Counties. Channel samples were collected at the three localities. All samples were analyzed for ash content, total sulphur content, crucible swelling number, and volatile content. The channel samples were analyzed for "pyritic" sulphur, “sulphate" sulphur, and "organic" sulphur. Thin sections of the samples were used in an estimation of anthraxylon and attritus contents.

In all the samples studied, volatile content of the coal seemed to be related to the ash content and the sulphur content. Crucible swelling number also …
