Conductance Of Organic Nitrogen Compounds At Their Melting Points, Leonard Joseph Burant

Bachelors’ Theses

Even though there are many practical applications using the conductance of fused salts, such as the commercial preparation of aluminum, sodium, potassium, calcium, and magnesium, there is very little in the literature on such conductance.

Because organic compounds as a class do not conduct as well as acids, bases, and salts, even less attention has been paid to the conductance of organic compounds in the fused state. Since the author has had some experience with organic preparations, it seemed worth while to prepare certain types of related heterocyclic organic compounds and to test their conductance in the fused state.

The Identification Of Alkyl Halides Through Conversion To Alkyl 3, 5 Dinitrobenzoates By A Reaction Between The Alkyl Halide And A Metallic Salt Of The Acid, James L. Finnerty

Bachelors’ Theses

To materially aid in the identification of a series of organic compounds one must develop a new system of derivatives or suggest better methods for preparing known derivatives. The problem of characterizing alkyl halides is one in which there is room for improvement, for the best derivatives of these compounds are now prepared by means of the Grignard reaction which may often fail to give satisfactory results. Moreover, there is a series of solid alkyl esters, the 3, 5 dinitrobenzoates, which serve very well for the identification of aliphatic alcohols, and which should be applied to the alkyl halides if …

Preparation And Physical Properties Of Some Unsymmetrically Substituted Ethanes, William F. Buth

Bachelors’ Theses

Early in 1947, while investigating the potentialities of various compounds for use as liquid dielectric materials, A method was found for the preparation of unsymmetrical ditolyl ethane by a condensation method using sulfuric acid. This material was thought to have excellent dielectric characteristics so it was prepared and tested. The tests were favorable enough, to warrant further investigation into the field of the unsymmetrical ethanes. Being aware of the physical properties required for a good liquid dielectric; it was proposed to prepare a few of the related compounds for which no data was known to exist and to select those …

A Study Of The Prussian Blue Test For Nitrogen, Marilyn M. Erickson

Bachelors’ Theses

The problem of obtaining good nitrogen tests on all types of organic compounds interested the author as a re­sult of past experience in the identification of organic compounds.

The practical application of a positive solution to this problem would be an aid to the students of charac­terization of organic compounds. It is necessary for them to make an elementary analysis in order to determine the class into which the unknown compound belongs. A nitrogen test which will give definite results will eliminate any doubt as to the presence of nitrogen.

The Trivalent State Of Uranium, Virginia M. Kubacki

Bachelors’ Theses

Besides being of practical importance in the preparation of compounds, the valence of an element is of theoretical significance because it is a clue to the electronic structure of the atom. In the case of elements which have several valences the relative stability and the means of changing from one state of oxidation to another are also important.

Uranium has valences of three, four, five, and six, but the reactivity of the trivalent uranium ion causes difficulties in the preparation of its compounds. Dr. Scott L. Kittsley in his investigation of the trivalency of uranium found that it is possible …

The Effect Of Metallic Fluorides On Oleic Acid At Elevated Temperatures, Lorraine W. Dupuis

Bachelors’ Theses

The problem of finding the effect of metallic fluorine compounds on oleic acid at elevated temperatures was presented in connection with the thesis of J.J. Wocasek of Marquette University. Doctor Wocasek had used fluorine compounds as catalysts in a.n attempt to find a sub­stitute for tung oil. He used the fluorides as catalysts in the esterification of glycerol with unsaturated acids.

The Synthesis And Certain Chemical Properties Of Several Aromatic Fluorides, Horst G. Schneider

Bachelors’ Theses

The preparation of organic fluorides, until only recently, had been seriously curtailed not only because of the difficulty experienced in their synthesis, but also due to the lack of information with regard to their physical and chemical properties. With the investigation of their characteristics, their great importance was for the first time fully realized. A concerted search was made for new modes of their preparation. That this search was rewarded is shown in part by the synthesis of several aromatic fluorides as a portion of this thesis.

Microradiography With Metal Powders, Wallace Kluck

Bachelors’ Theses

Microradiography is a comparatively recent development in the X-ray field. The term applies to the analysis of a thin specimen by photographing it with X-rays and subsequently enlarging the photograph to bring out minute structural elements. A microradiograph has several advantages over a photomicrograph. First of all it goes beyond the surface and reveals the internal structure of the specimen, a more important advantage at least as concerns this paper is the ability of the microradiograph to enable one to accurately determine the chemical elements making up the specimen.

The Effect Of Some Electrolytes On The Critical Solution Temperature Of The Phenol-Water System, Donald Gerald Leavitt

Bachelors’ Theses

A classical example of a system of liquids exhibiting partial miscibility is the phenol-water system. One of the earliest binary systems of this type to be Investigated, it has been the subject of much research and experimentation during the past sixty years. Its critical solution temperature has been determined by a multitude of investigators, the effect of a third component upon the system has been studied and many generalizations concerning partially miscible binary systems have been derived from these undertakings.

The studies which have been carried on regarding this system have been chiefly of theoretical interest, although in recent years …

A Study Of The Lassaigne Test For Nitrogen, Marion Ann Stout

Bachelors’ Theses

The elementary analysis of an organic compound is a determining factor in the characterization of the compound. The problem of this analysis was first encountered in organic characterization class where it was impossible to obtain a satisfactory test for nitrogen using the Lassaigne Method. It is the purpose of this thesis to testout the Lassaigne method under various conditions and to determine a set of conditions hereby the test will be positive.

The Synthesis And Some Physical Properties Of Certain Aromatic Fluorides, John W. Weldon

Bachelors’ Theses

The late discovery of methods of introduction of fluorine into organic compounds has retarded to some extent the commercial use of organic fluorides. The indirect methods used also prevented general preparation of fluorocompounds. However, the characteristic stability of many fluorine compounds has warranted both the preparation of numerous aromatic and aliphatic fluorides as well as a search for new methods of preparation. It 1s the purpose of this thesis to delineate the present methods of synthesis of aromatic fluorides and to show the influence of the substitution of fluorine on some of the physical properties of aromatic compounds.

The Determination Of Interfacial Tension Using Pendant Drop Method, Katherine Tellor

Bachelors’ Theses

Boundary tension is a measure of the free energy of a fluid interface. It is a term derived from the superficial analogy between the surface of a liquid and a stretched membrane. Just as the potential energy of a fluid mass in foot pound per pound is spoken of as a "head" in feet, so it is useful to speak of free energy of a fluid surface in ergs per square centimeter as a "tension" in dynes per centimeter.

The Electrodeposition Of Waxes From Emulsions, Richard Nebel

Bachelors’ Theses

At the beginning of the nineteenth century, electrochemistry became an established part of the science of chemistry. Volta believed in the existence of some definite relationship between chemical and electrical phenomena and his investigations led to the discovery of a means of converting chemical energy to electrical energy. His observations became the foundation upon which all modern electrochemistry is based. Volta alternated zinc and silver disks with paper soaked in salt water between each disk. This afforded a source of electrical energy which produced a current and became to be known as the Voltaic-pile.

The Effect Of Weak Acid On The Stability Of Burnishing Ink, Marcella Wamser

Bachelors’ Theses

By definition we find "An emulsion being a system containing two liquid phases, one of which is dispersed as globules in the other. That liquid which is broken up into globules is termed the dispersed phase, whilst the liquid surrounding the globules is known as the continuous phase or dispersing medium". If a small portion of benzene is poured into a large volume of water, it can be emulsified by simply shaking or agitating. Again, chloroform and water with shaking gives an emulsion.

The Determination Of Of Bromo Acid, Genevieve M. Stein

Bachelors’ Theses

The use of bromo acids in lipstick is comparatively recent. Since its use is so necessary to the modern lipstick in order to impart indelibility and staining power, the fact that bromo acid arouses a toxicity in the presence of castor oil in some individuals does not keep it from being one of the most important constituents of the stick. However, in order to keep the toxicity down to a minimum it is necessary to keep the type end amount of bromo acid under control. It is, therefore, highly important that a check on the amount of bromo acid be …

A Study Of The Fischer-Tropsch Synthesis, John E. Dornfeld

Bachelors’ Theses

In Continental Europe, where raw materials are at a premium, it is necessary to synthesize as much as possible. Hydrocarbons and their oxygenated derivatives are important for "everyday" life. When importation costs of raw materials are high, synthesis is necessary provided it can be done cheaper. The Fischer-Tropsch process is the answer for the needs of synthetic hydrocarbons and their oxygenated derivatives.

The purpose of this thesis is to obtain hydrocarbons and their oxygenated derivatives by the Fischer-Tropsch process in the wax range. From the literature it appears that no work in the industrial field is being done in the …
