Aromatic Acetals : Their Synthesis And Alkylation, Robert Conner Gass

University of the Pacific Theses and Dissertations

The purpose of this investigation was to study the known methods of forming acetals and find one or several that could be used in further investigation. In connection with the reactions, the use of various catalysts was pertinent. Some of the catalysts used were hydrogen chloride, calcium chloride, ferric chloride, aromatic sulfonic acids, and other. There was no data available comparing the sulfonic acids with the inorganic salts and mineral acids. For that reason one of the subsidiary problems of this investigation was such a comparison.

In order to investigate stability, several acetals were subjected to conditions intended to produce …

Montan Wax From California Lignites, Robert John Kvick

University of the Pacific Theses and Dissertations

Montan wax has been extracted from the lignite deposits of Germany since the early part of the twentieth century, The wax was named by von Boyen (1901), The word Montan is derived from the Latin term montanus meaning "of a mountain," The wax has found extensive uses in polishes, insulating materials, candles, explosives, and special applications in the rubber industry, The increased demand for waxes for industrial uses and the limited supply of domestic origin has made the study of the sources and characteristics of domestic waxes desirable, California lignite has been shown to be a valuable source of Montan …

Enrichment Of Tin Activity Through The Szilard-Chalmers Separation, Herta W. Spano

Chemistry and Chemical Biology ETDs

It was the purpose of this investigation to utilize the Szilard-Chalmers reaction in order to prepare tin solutions of high specific activity.

Tetraphenyl tin was chosen for the target compound. It is a white, crystalline solid of excellent thermal stability. No data have been reported in the literature on the rate of exchange between inorganic forms of tin and tetraphenyl tin but it seemed highly probable that this exchange would be very slow. Tetraphenyl tin is soluble in various organic solvents but insoluble in water, and this suggested solvent extraction as a possible means of separation of the activated tin …

The Peroxide Numbers Of Vegetable Oils, Robert J. Bruce

Bachelors’ Theses

A survey of the literature will indicate that the peroxide numbers of fats and oils are of importance in ii many industries. The dairy, fish oil, vegetable oil, and meat processing industries all have use for peroxide number determinations. as a measure of the degree of rancidity of their products. The paint industry has used it in the study of protective coatings, and the textile industry has used it in the study of the lubrication of fibers. All of these uses were applied to the study of partial oxidation of the samples under consideration.

Since the various methods in use …

Solubility Product Constants Of The Metallic Sulfides, Marvin Bernard Gordon

Theses and Dissertations

A survey of the chemical literature revealed a lack of agreement in the values reported by various investigators for the solubility product constants of the metallic sulfides. The object of this thesis was to obtain a reliable set of solubility product constant values for the metallic sulfides by means of thermodynamic calculations. Of considerable importance in calculating the values of the solubility product constants of the metallic sulfides is the value of the standard free energy of formation of the sulfide ion. A critical review of the values that have been reported by various investigators for this constant , including …

2-Pyrrolidinoethyl Esters Of Para Alkoxybenzoic And Para Alkox Alkoxycinnamic Acids, Michael James Fletcher

Master's Theses

One of the most important groups of local anesthetics is the class of alkyl and dialkylaminoalkyl esters of aromatic acids. Of these compounds, the diethylaminoethyl esters are particularly valuable.

It is obvious that pyrrolidine is merely a modified form of diethylamine. The purpose of this work is to learn the effect of substituting the N-pyrrolidyl nucleus for the diethyl amino nucleus in various esters of the local anesthetic type.

Phase Behavior Of Sodium Stearate In Anhydrous Cyclohexane, Walter Edward Reid Jr.

Master's Theses

Soap solutions, aqueous and non-aqueous, are characteristic in that they firm colloidal systems at certain concentrations, the properties of which are influenced by temperature and pressure. Application of the Gibbs phase rule to such systems makes possible the location of the various phases of a particular system and hence enables phase diagrams to be constructed. For systems of soap-hydrocarbons such as are found in fuels, beauty preparations, greases, medical preparations, etc., a phase diagram would show very readily the most satisfactory composition for the conditions desired.

Separation Of The Inorganic Cations Of Groups Ii And Ila By Means Of Paper Chromatography, Donald P. Schuelter

Bachelors’ Theses

The field of inorganic paper chromatography is in its infancy at the present time. Numerous papers have been published describing various methods for separation and hypothesis for the mechanism of the separations. Since the number of variables involved in chromatographic separations is so large it is rather difficult to establish any concrete principles. Many phases of the separations and their effects have been investigated but only too often they yield conflicting data. Up to the present time the majority of authors have confined their studies to a particular solvent and grade of filter paper.

The Identification Of Various Halogen Compounds Through Formation Of Quaternary Ammonium Salts, Kenneth E. Miller

Bachelors’ Theses

When, in the process of characterizing an organic compound, the compound has been definitely placed in one certain class, such as acids or alcohols, and all but a certain number of the compounds in the class have been eliminated by physical constants or functional groups, the final step is the preparation of suitable derivatives. If, however, the unknown falls into a class of compounds of such chemical nature that preparation of deriyatives is impossible, or, at the least, difficult, then the identification must depend entirely upon physical constants. This is frequency the case with alkyl halides. They must be identified …

Studies On Derivatives Of 3-Ethylphenanthrene, Eugene R. Miller

Bachelors’ Theses

The following thesis was undertaken to study the derivatives of 3 etbyl-phenanthrene. The problem was undertaken to familiarize the author with polynuclear aromatic hydrocarbons and the various reactions and unit processes which are involved in the synthesis or these derivatives. It is hoped that the experience gained in pursuing the objective of this thesis will provide a background which may prove valuable in future work tor an advanced degree and ultimately help to secure a position in some phase of research work dealing with biological compounds containing the phenanthrene configuration in its nucleus.

Phenol-Aldehyde-Condensation Synthesis Of A Possible Gerxioide And Fungioide, Bis(4-Fluoro-2-Hydroxyphenyl) Methane, Erwin A. Stern

Bachelors’ Theses

The successful synthesis of chlorinated and brominated dihydroxydlphenylmethanes during the last ten years and their use as germicides and fungicides coupled with the known effect of fluorine and alkyl groups upon phenol, warranted the attempted synthesis of fluorinated and alkylated dihydroxydiphenylmethanee . It is the purpose of this thesis to attempt the synthesis of fluorinated and alkylated dihydroxydiphenylmethanee for purposes of their use as germicides and fungicides.

Benzoylation Studies With A Compound Reported To Be Benzoyl Acid Sulfate And Analytical Studies On The Sample, Robert J. Peanasky

Bachelors’ Theses

A very valuable reagent in organic characterization work is benzoyl chloride. By interacting benzoyl chloride with any one of the general classes of compounds termed phenols, alcohols, and amines, solid and very satisfactory derivatives are usually produced. However, the action of this compound occurs rather slowly and the operator, unless especially careful, suffers from the lachrimatory effects of the reagent, benzoyl chloride. A sample was submitted to my major professor, Dr. C. R. Haymaker, by Gene LaFave who claimed that it was benzoyl acid sulfate. This compound was a solid not difficult to manipulate in contradistinction to the lachrimatory liquid …

The Synthesis Of 3-Ethyl-9-Acetylphenanthrene, Elizabeth R. Bender

Bachelors’ Theses

In 1929 , there was recognized a relatively small number of naturally occurring phenanthrene compounds as compared with those known today. These compounds include several groups of substances which are as strikingly similar in structure as they are different in their actions on the animal organism. For instance, the structure of the sterols and bile acids contain the perhydrocyclopentenophenanthrene ring system. Upon later research, it was found that the sex hormones and cardiac glycosides (heart poisons secreted by toads) have a structure very similar to this system. They are all derivatives of cyclopentenophenanthrene.

The Chemical Characteristics Of 8.0-Day I131 Produced By The Beta Decay Of 25-Minute Te131 In Organic Liquids, Francis J. Keneshea Jr.

Chemistry and Chemical Biology ETDs

In 1934 Szilard and Chalmers found that a large fraction of the radioactive iodine produced in the thermal neutron irradiation of ethyl iodide could be extracted from the irradiated material. The procedure followed was to add a trace of carrier iodine to the irradiated liquid, extract the iodine with an aqueous solution of a reducing agent and precipitate the iodide as silver iodide. The silver iodide precipitate obtained in this manner contained a large fraction of the iodine activity (25-minute I¹²⁸), at a high specific activity. Since ethyl iodide is not soluble in water and hence is not …

The Kinetics Of The Exchange Between Benzyl Iodide And Iodide Ion, Paul Stillson

Chemistry and Chemical Biology ETDs

A general form of an ion-molecule replacement reaction occurring at a saturated carbon atom may be represented by

Y^-+R-X⇋Y-R+X^-

where Y- is a negatively charged atom or group which can replace an atom or group X in the molecule R-X and R is any organic radical which is saturated at the point of attachment of X. The mechanisms which have been postulated for the above reaction may be divided into the following two groups: (1) those which assume primary dissociation of the neutral organic reaction into ions as the rate-determining step; (2) those which postulate the formation …

The Viscosities Of Mixtures Of Naturally Occurring Waxes And Oils At Various Temperatures, Edward L. Gavin

Bachelors’ Theses

The values of the viscosities of waxes, and of the viscosities of oils at various temperatures are numerous in the literature, but there is nothing to be found regarding the viscosities of oil and wax mixtures. Dr. John R. Koch, professor of chemistry, Marquette University, pointed out the lack of such information. It is with this in mind that this thesis was undertaken.

A Study Of The Equilibrium Distribution Of A Solute Between Two Immiscible Solvents, Francis A. Smith

Bachelors’ Theses

Because of the wide application of Distribution Law, for it should hold for the distribution of a dissolved substance between any two phases, for instance, liquid-liquid, gas-liquid, liquid-solid, and so forth, this subject was choosen for further investigation. The tendency for a solute to distribute itself between two immiscible solvents, so that the concentration ratio is a constant, is a direct consequence of the thermodynamic requirements for equilibrium. The reactions of various organic and inorganic acids distributed between water and several organic solvents will be studied.

The Identification Of Alkyl Halides Through Their Conversion To Alkyl 3,5, Dinitrobenzoates By A Reaction Between The Alkyl Halide And The Silver Salt Of The Acid, Nicholas Michel Le Mieux

Bachelors’ Theses

In qualitative organic analysis the final test for the identification of any compound is the preparation of some solid derivative of definite molting point. For routine work it is quite essential that this derivative be easily prepared and purified.

A large number of general derivatives for classes of compounds are now commonly used, such as, the aryl sulfonyl derivatives of amines, the p-bromophenacyl and the p-bromobenzyl eaters of the acids, and the 3,5 dinitrobenzoate esters of the alcohols. However, in the identification of alkyl halides there Is no general type of derivative that possesses the above mentioned characteristics. It la …

The Saponification And Chlorine Determination Of Alkyl Chlorobenzoates To Determine Their Identity And Purity, Joan Bardele

Bachelors’ Theses

Many of the present reagents tor the preparation of alco­hol derivatives are deficient in at least one respect. A preparative investigation was made by Mr. Robert Johnson of alkyl chlorobenzoates, by substitution of benzoyl chlorides on aloohols, since various benzoyl chlorides are now available com­mercially. Mr. Johnson presented a thesis on the "Preparation of Alkyl Chlorobenzoates And Their Application As Alcohol Derivatives". As a result or his work thirty eaters previously not reported in literature were prepared and their melting points and boiling points and refractive indices determined.

In order to give an indication of the identity and purity ot …

The Preparation Of Long Chain Secondary Aliphatic Amines, Robert Fay Betts

Bachelors’ Theses

As organic chemistry has always seemed to be the most interesting study to me, I have chosen this particular branch ­ or chemistry for a thesis.

I found through correspondence with some of the larger petroleum companies in the United States that the preparation of long chain secondary amines would constitute a good thesis topic because these compounds have begun to assume importance as additives to lubricating oil.
