The Extraction Of Tantalum And Columbium From Tantalite, Stanley P. Wisniewski

Bachelors’ Theses

In the summer of 1932, the Milwaukee Public Museum, sent an expedition to the Bad Lands and Black Hills of South Dakota, under the direction of Dr. Ira Edwards, Curator of Geology in that institution. It was at this time that the author, a member of this group, while studying the pegmatites of the Black Hills, became interested in the tantalum-columbium bearing minerals of that region, namely tantalite and columbite. At that time the writer made a detailed mineralogical study of these two minerals, as well as a thorough investigation of their occurrence in that region. In the fall of …

A Contribution To The Preparation Of Synthetic Rubber From Butyl Alcohol, Rosalia Aloisia Leutgoeb

Bachelors’ Theses

Rubber, on account of its almost universal usefulness is one of the important materials of modern time. The unequalled utility of it is found in its physical properties, such as elasticity and toughness, which are not possessed by other plastic substances.

Some Contributions To Iodometric Technique, Justin Kimber Dyche

University of the Pacific Theses and Dissertations

Analysis is a very important branch of chemistry, for it is such a practical part of the science. Analysis is itself divided into two parts. Qualitative analysis discovers what things are present in the material in question. Quantitative analysis then determines how much of each ingredient is present. This thesis considers a limited section of quantitative analysis.

This thesis deals with the use of iodine in volumetric analysis, which is called either iodimetry or iodometry. In this type of analysis, the iodine is used in solution and reacts with some other material, also in solution, and takes up electrons. That …

The Effect Of Halowax 1012, 1013 & 1014 On The Melting Points Of Various Waxes, Louis Henry Kroening

Bachelors’ Theses

This thesis is concerned with the melting points of various waxes and the effect of Halowax 1012, 1013 and 1014 upon their physical constants. Interest in this problem was aroused "by the fact that Halowax as shown by Nathan Smith in his thesis, "The Effect of Halowax Upon Lubricating Oils and Greases”, decreases the viscosity of oils. Since lubricating oils contain waxes it is logical to expect that this decrease in viscosity is due to the lowering of the melting point of the waxes present. It was to investigate the truth of this assumption that this work was begun.

A Study Of Melting Points Of Various Ternary Mixtures Of Waxes, Leonard Anthony Veranth

A Contribution To The Preparation Of Synthetic Rubber From Butadiene. Ii., Joseph Patrick Iding

Bachelors’ Theses

Since the World War, the production of synthetic rubber has become the problem not only of the laboratory, but of commerce as well. Several factors demanded this research.

In the first place, the World War made the dependence of countries on each other strikingly evident in several ways, one of which was the need for rubber by great nations whose situations prohibited the planting of the rubber tree and consequently put them under obligation to other countries for their supply.

And now in the last few years this demand for rubber has been increased enormously, through the increased production of …

A Study Of The Cooling Curve Of Several Waxes And Various Binary Mixtures Of These Waxes, Casimir A. Smyk

Bachelors’ Theses

A cooling curve may be defined as a graphic representation of the relationship which exists in the elapse of time and temperature of a substance surrounded by a medium of a temperature lower than itself. There is no heat added to the substance and the only heat taken away from the substance is by means of the surrounding medium. It is time plotted against temperature. Time on the x-axis and temperature on the y-axis. Many methods have been mentioned for the determination of purity and identification of a wax. But the methods are not standardized because of the length and …

The Effect Of Halowax On Lubricating Oil And Grease: The Instability Of Aluminum Grease In Regard To Viscosity, Nathan Smith

Bachelors’ Theses

This thesis is concerned with lubricating oils and solid lubricants. The initial problem in this research was the effect of Halowax 1012, 1013, and 1014 on lubricating oil. During the investigation, however, it was observed that the addition of Halowax to the lubricating oils formed a false gel at ordinary temperature, the consistency depending on the percentage of Halowax added. The result no longer favored continued research since the lubricating oil was made impractical. The problem then lent itself to the influence of Halowax on solid lubricants, in particular lubricating greases. It was on this phase of the investigation that …

Wax Analysis With Special Reference To Montan, Spermaceti, And Chinese Insect Wax, Margaret M. Plonsker, Margaret E. Seippel

Bachelors’ Theses

The presentation of this thesis under joint authorship finds its justification in the fact that much of the experimental work, though performed individually, is of such a nature as to warrant a unified description. In this way the reader is afforded a better representation and clearer conception of the problem, and a substantial guide for further investigation. Though much work has been done in the field of wax analysis, little is known of the higher fatty acids and alcohols of many of the waxes. Their isolation has been infrequent, and few if any of their derivatives have been formed. It …

Steric Hindrance In The Ketonic Splitting Of Substituted Acetoacetic Ester, Claude Stanley Abshier

Throwing Power Of A Chromium Plating Bath Containing Hydrofluoric Acid Instead Of Sulfphuric Acid, Clarence E. Barta

Bachelors’ Theses

Chromium was discovered in 1797 by a Frence Chemist named Vauquelin who gave it its name from a Greek word for color because of its variety of colors which its various compounds show. The electrode-deposition of Chromium from a Chromium acid solution has been an accomplished feature for the past century but it has only been in the past few years that the mechanism of the process has been sufficiently understood to permit its commercial application.

Harding and Barrows state that it is possible to ob­tain satisfactory Chromium deposits from Chromic acid baths containing compounds other than sulfuric acid which …

A Study Of The Inhibiting Value Of Various Separators On The Plating Of Lead, Lawrence E. Ehrnst

Bachelors’ Theses

This thesis was suggested by the work of Mr. B. J. Pozorski and Mr. W. Adashek. Mr. Pozorski investigated the inhibiting qualities of various separators when placed between two platinum electrodes in a copper sulfate solution. Mr. Adashek worked on the efficiency of various lead plating solutions using lead electrodes and electrlyes containing soluble lead salts. Combining the work of these men, the author is investigating the prohibitive plating properties of various separator using a lead plating solution. By so doing, the investigation has a closer relationship to the actual performance of the storage battery .

Current Efficiency Of Various Chromium Plating Baths, Clarence R. Hanus

Bachelors’ Theses

Chromium is one of the hardest metals and when properly plated gives a beautiful lustre. It has a fine resistance to oxidizing agents and does not tarnish up to 600°C. Oxygen has little effect on chromium plate, making the latter invaluable for embellishments and decorative purposes.

However, there are difficulties to be overcome in chromium plating, such as,

1. Poor throwing power.
2. Formation of trivalent chromium.
3. Evolution of hydrogen at the cathode.

It has been found that current efficiency is low, resulting in low throwing power, uneven plating and waste of electric energy.

In this thesis it will be attempted to …

The Influence Of A Halowax Oil On The Viscosity Of Lubricating Oil At Various Temperature, Clarence J. Riordan

Bachelors’ Theses

Halowax Oil is used as a.filler in plastic compounds, on wood as an insecticide against termites, and the Petroleum industry finds it a very good valve lubricant in internal combustion engines and a solvent for tarry residues which deposit on combustion chambers. Due to its low viscosity and very low congealing point it would therefore seem logical to investigate this further with the idea of using Halogenated oils as winter lubricants for automobile engines. The work naturally suggested further study, such as its effect on corrosion of steel, aluminum, iron and copper, the flash and fire points, viscosity at various …

The Viscosity Of Liquids, Mary Bede Brielmaier

Bachelors’ Theses

The Effect Of Alternating Current On The Rectifying Properties Of Metallic Salts In Contact With Metals, William Howard Schumaker

Bachelors’ Theses

However much may be said regarding the advantages of direct current, there is little doubt at present, that from the viewpoint of power generation and transmission, alternating current has considerable advantages over direct current. While such is the case, there is, and probably always will be, a need for direct current. According to our present development, this direct current is indispensable in wireless work, radio, and in the laboratory test shops, where it is necessary to work with very sensitive meters, which are inexpensive and easy enough to secure for direct current measurements, but which necessitates an elaborate and costly …

Current Efficiency Of The Commercial Chromium Plating Bath, John Kaczmarowski

Bachelors’ Theses

The subject matter of this thesis deals with the character of the chromium plate, the amount of hydrogen liberated at the cathode, the weight of the chromium deposited, and the cathode efficiency.

This investigation was made for the purpose of aiding .further research work to increase the cathode efficiency of the chromium plating bath. If greater efficiency can be obtained, then, chromium, as nickel, can be plated on small articles in rotating barrels.

A Volumetric Method Of Chromium Determination With Mercurous Nitrate, Gerald W. Lawton

Bachelors’ Theses

Boncyk in his research on potentiometric titrations, made the observation that apparently mercurous nitrate could be used to titrate chromic acid solution. He used potassium iodide as an outside indicator and found that a slight excess of mercurous nitrate gave a gray precipitate with potassium iodide solution. The precipitate seemed to indicate the end point, or the neutralization of the chromic acid; a slight excess of the mercurous nitrate causing the immediate formation of a gray precipitate. Not knowing the exact normality and purity of the solutions used, he could not ascertain whether the gray was the true end point, …

A Study Of The Plating Prohibitive Properties Of Various Separators, Bruno J. Pozorski

Bachelors’ Theses

The problem of this thesis is to study the plating prohibitive properties of the various materials commonly used in the manufacturing of separators, and to indicate which material would be most serviceable and feasible in a separator. At one time positives and negatives were kept not more than 0.25 inches apart, with the idea of reducing the intervening layers of electrolyte, and, therefore, the internal resistance of the cell, as much as possible. It was, however, found that the output could actually be increased by putting the plates at greater distances, the fact being that the larger bulk of solution …

A Study Of The Miscibility Of Various Liquids With Ethylene Glycol, Joseph J. Furlong

Bachelors’ Theses

Ethylene glycol is a compound possessing great interest, both from a theoretical and a practical standpoint. In its properties it lies midway between ethyl alcohol, C₂H₅0H, and glycerol, C₃H₅(0H)₃, the three compounds together forming an homologous series of alcohols.

A few years ago this substance was a scientific curiosity, produced solely by laboratory methods, and without any commercial value, although it had been known for more than sixty years. Today the manufacturers cannot produce enough glycol to satisfy the growing demand. The DuPont organization wanted to use it in a …

A Study Of Halowas Oil In Reference To Its Properties And Uses, Joseph F. Hoffman

The Corrosion Prevention Qualities Of The Aldehydes, Oliver R. Mackenzie

Bachelors’ Theses

In preparing the natural ore of iron for commercial use, man has met with great success. At present, approximately 36,000,000 tons of steel are produced yearly in the United States alone. Man, however, has been confronted by an unceasing, tireless agent which tends to return the newly manufactured steel to the oxide of the iron, a condition similar to that of the natural ore. To prevent this action, man has put up a continual fight, using many preventitlves, but to date corrosion has overcome all of man’s contrivances and emerged the winner.
