A Geomagnetic Survey Of Parts Of Pierce, Benson, Sheridan And Wells Counties, Harald C. Haraldson
Theses and Dissertations
A magnetometer survey in respect to oil exploration is a regional reconnaissance tool and, therefore, it is customary to check an interesting magnetic anomaly with a seismograph or gravimeter. An exception to this is found in micro magnetic surveys which, because of their detailed nature 28 nature, may serve as a cheek on the other types of geophysical surveying.
The two large magnetic highs may be more areas in the basement rocks, and they may indicate structure. However, the large eastward-trending magnetic high area on the west side of the map area is quite possibly due to a regional increase …

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

Collector-Depressant Equilibria For The Flotation System Potassium Ethyl Xanthate-Potassium Cyanide-Molybdenite, Connell Bolton Roberts
Collector-Depressant Equilibria For The Flotation System Potassium Ethyl Xanthate-Potassium Cyanide-Molybdenite, Connell Bolton Roberts
Theses and Dissertations
This dissertation involves a study of the collector-depressant equilibria of the flotation system potassium ethyl xanthate-potassium cyanide-molybdenite, based upon mineral-air bubble contact measurements made by a modified captive bubble technique. The Cook theory of single site free acid adsorption is used to interpret the data. The standard free energies of adsorption of ethyl xanthic acid and hydrocyanic acid on molybdenite are calculated.
Thermodynamic Properties Of Water Absorbed On Silica, Conrad V. Hatch
Thermodynamic Properties Of Water Absorbed On Silica, Conrad V. Hatch
Theses and Dissertations
The object of the work presented in this thesis was to obtain quantitative values of the thermodynamic changes in water upon adsorption by silica. Two methods were used. The first was a determination of the differential entropy and heat of adsorption independent of any theory of adsorption. The second method included a new interpretation of the "c" constant of the Brunauer, Emmett, and Teller Theory in which c was expressed in terms of the standard free energy of adsorption. The experimental data gave satisfactory results in determining the differential heat and entropy of adsorption. The results obtained in determining the …

Collector-Depressant Equilibria In The Flotation Of Molybdenite, Robert Létrenne Andelin
Collector-Depressant Equilibria In The Flotation Of Molybdenite, Robert Létrenne Andelin
Theses and Dissertations
This dissertation presents the results of research on the flotation system potassium n-amyl xanthate - sodium sulfide - molybdenite. The purposes of the research were (1) to determine the theoretical collector-depressant equilibria conditions of this system necessary for the flotation or depression of molybdenite, (2) to ascertain the mechanism of adsorption or the collector potassium n-amyl xanthate and the depressant sodium sulfide on molybdenite, and (3) to calculate the standard free energy of adsorption on molybdenite of the collector and depressant in this system. To accomplish these purposes it was necessary to develop a satisfactory experimental method for the controlled …
Further Studies Of The Reactions Of Quinoxaline And 2-Methylquinoxaline, Marcus N. Myers
Further Studies Of The Reactions Of Quinoxaline And 2-Methylquinoxaline, Marcus N. Myers
Theses and Dissertations
The present investigation was also made with the object of preparing the vinylquinoxalines and studying their 1,4- addition reactions. The attempts to prepare vinylquinoxalines were unsuccessful. However, sodium acetylide reacted with 2,3-dichloroquinoxaline to give a new compound which (from its analysis and properties) appears to be 2,3-bis(1-hydroxyethyl) quinoxaline . This new compound should be investigated further , as it may prove to be an intermediate in the preparation of vinylquinoxalines. The preparation of 2-methylquinoxaline has become very simple by the use of the method of Jones, Kornfeld and McLaughlin^5, which consists of condensing o-phenylenediamine with pyruvic aldehyde. The condensation of …
