Honors Theses

The aim of the present research is therefore to investigate the clevage of organosiloxanes by several metal halides that were omitted from consideration in previous experminetal work.

Studies Of Aryl Hypochlorites, Edwards Stengle Atwood

Honors Theses

Of all the reactions of the esters of hypohalous acids, those least documented are the reactions and characteristics of the phenolic esters. This includes the reactions of hypohalites in the presence of a strong Lewis acid, such as aluminum trichloride. Only one reaction has been published in which an organic hypohalite is reacted in the presence of a strong Lewis acid; this dealt with an alkyl hypochlorite. Berman and Lowy (1) reacted tertiary butyl hypochlorite with benzene in the presence of aluminum trichloride, reporting tertiary butylbenzene as the product.

A Study Of The Kolbe Electrolysis Using Mixed Mono-Ethyl Glutarate And Mono-Ethyl Malonate, Richard John Gilbert

Honors Theses

The study of electrolytic reactions of organic compounds was first attempted soon after the discovery of the electrolysis if water in 1800. These reactions were not used in synthesis until after 1847 when Kolbe discovered that aliphatic acids. The field has greatly increased since then, and it is now possible to carry out synthesis by electrolytic reduction, oxidation, cathodic coupling, anodic coupling, and substitution. It was the purpose of this work to attempt one mixed Kolbe reaction and analyze its products qualitatively not quantitatively. If time permitted, quantitative analysis would be attempted.

A Study Of Stable Ion-Pairs, James Carlton Garrison

Honors Theses

A study was made of the ion-pair that forms when the commercial surfactant, Ethoquad 18/25, is mixed with azo dyes such as methyl orange or methyl red. The study determined some of the physical characteristics of the ion-pair, and two attempts were made to determine the structure. Through a series of titrations it was found that the ion-pair is sensitive to pH and can be dissociated in strong acid solution. An attempt to determine the structure of the complex by infra-red analysis failed. The equilibrium constants for the Ethoquad and two different dyes were determined. On the basis of the …

A Polarographic Analysis Of The Tetracyanoaurate (Iii) And The Dicyanoaurate (I) Complexes, Richard Joseph Klimowski

Honors Theses

A method for determination of the dicyanoaurate and tetracyanoaurate complexes using polarography has been investigated. Whereas distinct wave forms (current-voltage plots) are obtainable, many interference problems exist. Previous work has been confirmed and new data added. Dicyanoaurate I (Au(CN)2) has been satisfactorily investigated and may be classified as a stable complex. Tetracyanoaurate III (Au(CN)4) has been investigated and must be classified as unstable. This a polarographic method of quantitative analysis for a simultaneous determination of these complexes seems remote.

The Cyclization Of A Diazoketone With Boron Trifluoride Etherate, Stephen Joseph Isser

Honors Theses

Normally, a diazoketone reacts with an acid to form a substituted methyl ketone. When a nucleophilic center is present at an α or β position of R, this reaction may lead to the formation of a cyclic ketone (11). It was the purpose of this research to investigate the cyclization of the aliphatic methoxydiazoketone, 1-diazo-4-methoxy-4-phenyl-2-butanone (I), when treated with BF3 in ether, to give the five-membered ring 5-phenyltetrahydrofuranone-3 (II).

The D O Acidity Function For Aqueous Sodium Hydroxide Solutions, James T. Macgregor

Studies Of The Reactions Of 1-Diazo-3-Methoxy-3-Phenyl-2-Propanone With Boron Trifluoride Etherate, Ross Grant Mackinnon

Honors Theses

Normally the reaction of diazo ketones wih acids yields straight chain-substituted ketones. The product can be a cyclic compound if within the diazo ketone there lies a nucleophilic center at the α or β position.

Photochemical Reactions Of Benzophenone And Cyclohexene, Michael I. Goldberg

Honors Theses

Aldehydes and ketones absorb weakly in the 290 mμ region of the ultraviolet spectrum, and also at 200 mμ (this wavelength region being analogous to that occurring in the spectra of olefinic compounds). This weak absorption band in the carbonyl absorption spectrum can be attributed to an n → π* transmission of a non-bonding electron on the oxygen atom to an anti-bonding π orbital in the multiple bond to give a singlet state. It is this absorption and consequent formation of an energized state which appears responsible for most of the photochemical transformation of saturated ketones in condensed (liquid) phases. …

Kinetic Study Of The Autocatalytic" Photodeboronation Of Benzeneboronic Acid In Phosphoric Acid Media, Bradley C. Bockrath

Honors Theses

Kinetic studies are often valuable in the investigation of reaction mechanisms. They can reveal the molecularity of a reaction and perhaps give an indication of possible intermediate steps. Comparisons of rate studies, such as kinetic isotope effects, can indicate the rate determining step of a reaction. Finally, rate studies can reveal when changes in reaction mechanism accompany changes in one or more kinetically significant variables. This study investigates the possibility of a new or altered reaction mechanism as one kinetic variable is changed. The reaction of interest is the hydrolysis of benzeneboronic acid in concentrated phosphoric acid media.

The Preparation Of 2-Aryl-3-Methyl-4-Metathiazanones And 2-Aryl-3-Methyl-4-Thiazolidones, John Charles Wilson

Honors Theses

It had been found that 3-mercaptopropanoic acid would react readily with ammonia or primary amines yielding Schiff bases which when reacted aryl aldehydes would give 2 and 2,3 disubstituted 4-metathiazanones. The report included a variety of substituted benzaldehydes, pyridyl and thienyl carboxaldehydes, ammonia, and alkyl and aralkylamines.

Water Chemistry Survey Of Boulder Basin, Lake Mead, P. R. Tramutt, Bureau Of Reclamation

Publications (WR)

The survey results indicate that the impoundment of water behind Hoover Dam has not adversely affected the dissolved oxygen (DO) content and that water quality and DO content were uniform regardless of depth. The study made in April-May 1964 will provide water quality data of Lake Mead prior to releases from Lake Powell as a basis for evaluating Lake Powell's effect on water quality and limnology of Lake Mead. The performance of a DO analyzer was tested and found unsatisfactory at depths below 150 ft. Parameters tested by standard chemical analyses of water samples in the Denver Laboratory and by …

Helianthus Annuus - The Separation And Identification Of A New Fatty Acid, Donald C. Gruber

Masters Theses

Introduction

The term "fatty acids" was first applied principally to saturated, monobasic carboxylic acids and especially to long chain acids derived from animal and vegetable oils. As time passed and the knowledge of natural fats increased, polyunsaturated, hydroxy, keto and branched chain acids were also found as constituents of these fats and oils and these also came under the heading of fatty acids. Even acids containing alicyclic substituents were found.

More recently the term 11 fatty acid" has been applied to include saturated and unsaturated monobasic carboxylic acids and several other series of substituted acids having carbon skeletons similar to …

Synthesis Of Potential Anti-Tumor Agents Related To Ethanolamine. I. Phenoxyacetic Acid Derivatives, Kenneth Wayne Rodarmer

Masters Theses

Introduction

Derivatives of phenoxyacetic acid (PAA), because of their activity as synthetic auxins, have long been of interest in the botanical sciences. PAA itself was noted (29) to have some auxin activity. However, real interest in PAA derivatives awaited the establishment of 2,4-dichlorophenoxyacetic acid (2,4-D) as a powerful, selective herbicide (12). An enormous number of PAA analogs and homologs have been investigated for their potential in the herbicide industry, and the statistical evidence from these investigations has been used as the basis for several interesting and sometimes conflicting theories of auxin mechanisms (17, 26, 23, 27).

Physiological effects of PAA …

A Comparison Of Blood Pressure Readings Taken On Preoperative Patients During Hospital Admission And One And One-Half To Three Hours Later, Susan Lee Woodward

Loma Linda University Electronic Theses, Dissertations & Projects

A "before-after" type experimental study was conducted to find an advantageous time to record baseline blood pressure readings on preoperative patients, which could be referred to following surgery and interpreted as representative of normal for the patients. A review of medical and nursing literature revealed that there is a need to established a blood pressure reading indicative of normal for each patient prior to surgery. Because literature substantiated its acceptance, the ausculatory method of taking indirect arterial blood pressure readings was the technique utilized in this study. Sixty conveniently selected general elective surgical patients, twenty-five to forty-five years of age, …

Interpretation Of Activity Orders By Physicians And Nurses, Sharon Jean Staley

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to find out the interpretations of activity orders by physicians and nurses in one selected hospital, and to compare the findings of this study to Roose's study to develop a guide for these activity orders. Roose, who surveyed the interpretations of activity orders by physicians and nurses in a group of hospitals, recommended that the same study be replicated in one hospital to find out the discrepancies of interpretation by physicians and nurses in one environment. This study, based on that recommendation, surveyed interpretations by physicians and nurses of four activity orders: (1) complete …

Graphical Solutions To Frequently Encountered Fluid Flow Problems, Roland W. Jeppson

Reports

Introduction

Graphical methods are often used by engineers to solve frequently used or complex formulas which require trial and error solutions. Perhaps the best known graphical tool used by the engineer is the slide rule, but anyone familiar with its use will recognize its limitations both in time and accuracy. For many problems which involve many repetitive computations high speed digital or analog computers are the most effective tools for solution. There are, however, many problems requiring considerable engineering time for slide rule solutions where solutions are not justifiable on computers. The use of nomograms for such problems is desirable. …

The Extent To Which Patients Follow Their Low-Cholesterol Diets, Beverly Jo Peterson

Loma Linda University Electronic Theses, Dissertations & Projects

This exploratory study was conducted to discover to what extent patients follow their low-cholesterol diets. If they did not, the reasons were investigated. It was hoped that the findings would aid in defining areas of instruction which need greater emphasis when patients receive instruction concerning a low-cholesterol diet.

An interview guide was used as a data gathering tool. The dietitians at one private teaching hospital recorded all dietary prescriptions sent to them during the specified period and ten physicians were contacted for permission to include their patients in the study. The patients were then contacted by telephone and the interviews …

A Comparison Of Axillary And Rectal Temperatures In Children, Doris Payne

Loma Linda University Electronic Theses, Dissertations & Projects

This study was conducted on seventy-five children, three to eight years of age. The purpose was to compare a three-minute axillary with a three-minute rectal temperature. Known factors which might influence the findings were eliminated. These were emotional stress, physical exercise, antipyretic medications, cooling and heating measures, gastro-intestinal disturbances, and croupettes or oxygen tents. The range of the difference between the temperatures was from 0.8 degrees to 2.2 degrees with the mean difference of 1.13 degrees. A little less than half of the temperatures had one degree of difference. An additional thirty-two per cent were within 0.2 degrees of being …
