The Production Of Oxalic, Citric, And Gluconic Acids From Plantation Molasses, John A. Ruth
The Production Of Oxalic, Citric, And Gluconic Acids From Plantation Molasses, John A. Ruth
University of the Pacific Theses and Dissertations
This research was undertaken for the purpose of developing a process for producing citric and gluconic acids from plantation molasses.
There is an evident need for such a process. At the present time, these acids are being produced by processes in which refined sugar is the principal raw material. If molasses could be used in place of refined sugar, the cost of raw materials would be reduced by approximately ninety percent. In addition, a waste product would be utilized.
The scope of this problem is very broad. Its solution will involve the solving of many problems of widely varying natures. …

The Relation Of The Native Forest Cover To The Physical And Chemical Nature Of The Soils Of The Mammoth Cave National Park Area, Sheppard Walker
The Relation Of The Native Forest Cover To The Physical And Chemical Nature Of The Soils Of The Mammoth Cave National Park Area, Sheppard Walker
Masters Theses & Specialist Projects
This study was undertaken for the purpose of determining the relation existing between the native forest cover and the chemical and physical properties of the soils of the Mammoth Cave National Park area. The study was suggested by certain references in the literature to a correlation existing between forest cover and the geological, chemical and physical nature of soils of this area. The recent attempt at reforestation in the Mammoth Cave National Park area renders such a study timely, and it is believed that the results reported in this paper will materially aid the Mammoth Cave National Park Commission and …
A Study On The Liesegang Phenomenon, Earl Francis Rothemich
A Study On The Liesegang Phenomenon, Earl Francis Rothemich
Honors Theses
This work is a continuation of an attempt to explain the Liesegang Phenomenon by using probing electrodes inside the gel. A study of what happens as one salt diffuses into a gel containing another salt with the precipitation of the reaction product in the gel, as well as the case of diffusion of a salt into a gel containing a small amount as the same salt has been made.
By the use of the probing electrodes it is possible to actually get inside the gel and in this manner observe how the concentration of the salt in the gel changes …
A Study Of The Effect Of Quinhydrone On The Time Of Set Of Silicic Acid Gells And Of The Effect Of Silicic Acid Gel On The Determination Of Ph By The Quinhydrone Electrode, James E. Malone
Honors Theses
The studies discussed in this report are supplementary to the work being done at Union College on silicic acid gels. In as much data has been taken in this work using pH as determined by the quinhydrone electrode, it was desired that a study be made of the effect of quinhydrone on the gel and of gel on the quinhydrone determinations. The pH of gels during their setting has been worked on and the first part of the experiment deals with the effect of quinhydrone on the time of set of silicic acid gel. Then it was desired to know …
The Thermal Dissociation Of Lithium Hydride, Benjamin M. Walker
The Thermal Dissociation Of Lithium Hydride, Benjamin M. Walker
Honors Theses
In previous work at the Union College laboratory a method was finally developed which overcame the difficulties of the earlier studies of calcium-hydrogen equilibrium. The results obtained were in good agreement with the best work of other investigators. In the present work, an attempt was made to extend this method to a study of the lithium-hydrogen equilibrium.
Precipitations In Gels, Bernard Freeman
Precipitations In Gels, Bernard Freeman
Honors Theses
Numerous investigations of reactions in gels have been conducted since Liesegang’s1 discovery, in 1896, of the periodic nature of silver chromate. Liesegang obtained rhythmic bands by the diffusion of silver nitrate in a gel containing K2Cr2O7.
A Study Of The Velocity Of Ions In Silica Gels When Under The Influence Of A Potential, John Galaba
A Study Of The Velocity Of Ions In Silica Gels When Under The Influence Of A Potential, John Galaba
Honors Theses
There is speculation among chemists as to the structure of gels. In an effort to get information on this subject, chemists have studied the properties of and reactions in gels. The results have led to conflicting theories. This work measuring the velocity of ions in silica gel has been done in the hope that it may add to the knowledge of the behavior of gels and furnish a further clue towards the correct structure of silica gels.
A Brief Study Of The Cherokee Formation Outcrop In Kansas, Roland G. Holmes
A Brief Study Of The Cherokee Formation Outcrop In Kansas, Roland G. Holmes
Electronic Theses & Dissertations
The Cherokee formation is one of the important rock formations of Kansas. There has been much work done upon the coal beds of this formation but so far as is shown by a search of the available literature, there has been no work carried on making a study of the rock beds of the formation by means of chemical analysis.
This paper is an endeavour to do three things: (1) to make a brief study of the rocks of the Cherokee formation at various horizons, (2) to attempt to show by chemical analysis the position of the land mass from …
Leaching Copper Minerals In The Butte District, Kenneth C. Bellows
Leaching Copper Minerals In The Butte District, Kenneth C. Bellows
Bachelors Theses and Reports, 1928 - 1970
The history of mining in Butte is woven about three of our principal metals. The gold placers first attracted the attention of miners in 1863, and reached their peak production in 1867. Silver was the second metal mined, and this operation required the erection of large mills with a consequent increase in mining activity that made the district a prominent producer. Although the presence of copper in the silver ore had been known, the credit for the first development of the copper veins is due Senator W. A. Clark. The original Colusa, Mining Chief, and Gambetta claims were developed to …
A Study Of Montana Bentonite, William P. Ryan
A Study Of Montana Bentonite, William P. Ryan
Bachelors Theses and Reports, 1928 - 1970
Research has been undertaken both under Government and private auspices in an endeavor to develop uses for bentonite. Perhaps, the work done to date has had only in consideration the possible industrial importance of bentonite. No simple, quick methods for the determination of the properties or qualities of any particular bentonite have been developed.
In an attempt to establish whether or not there is a means of making rapid simple determinations of the quality of Montana bentonitic clays, and in particular, with regard to the uses to which the clays may be suited. The problem also involves a study of …
The Calcite Veins Of The Livingston Formation, John Moore Conrow
The Calcite Veins Of The Livingston Formation, John Moore Conrow
Bachelors Theses and Reports, 1928 - 1970
An interesting group of calcite veins occur near Livingston Montana in a zone about eight miles wide and forty miles long in the edge of the Plains region of Montana in front of the Main ranges. The zone extends from the Boulder River south of Big Timber, through Springdale and Hunters Hot Springs, to Potter's Basin just north of Wilsall in Park County. The group of veins is particularly interesting because they cut relatively flat lying strata, suggest a structural relationship to one another, and they are nearly pure calcite.
The present investigation was to determine the position of the …
A Microscopic Study Of Some Volcanic Rocks In The Vicinity Of Butte, Evan Gustafson
A Microscopic Study Of Some Volcanic Rocks In The Vicinity Of Butte, Evan Gustafson
Bachelors Theses and Reports, 1928 - 1970
The rhyolite rocks in the vicinity of Big Butte present a very interesting, though complicated study. It seems that no extensive or conclusive work has ever been done upon these extrusives.
I have found that the rhyolites present a very interesting problem, especially microscopically, and that no doubt an intensive study along these lines will solve the problems concerning age relations of different flows and origin of the magma that produced the material for emanations.
Methods Of Obtaining Asymptotes, Paul Sweetland
Methods Of Obtaining Asymptotes, Paul Sweetland
Master's Theses
The purpose of this thesis is to present in logical order the more important methods of obtaining asymptotes. In several cases where two or more different methods for obtaining the same type of asymptotes were found the simpler method is given first and then the more difficult method. Most of the simpler methods are based on Analytic Geometry, while the more difficult are based on the Calculus.
Effect Of Impurities Upon Current Efficiency In The Electrolysis Of Zinc Sulphate Solution, Robert Jess Smith
Effect Of Impurities Upon Current Efficiency In The Electrolysis Of Zinc Sulphate Solution, Robert Jess Smith
Bachelors Theses and Reports, 1928 - 1970
There are many elements which are detrimental to the current efficiency in the electrolysis of zinc sulphate solution. Fortunately the majority of these elements are easily removed in the purification process and cause no further trouble. The elements that are likely to cause trouble in ordinary plant operations are antimony, arsenic, cobalt, nickel, manganese and germanium. The following tests were made to determine the mutual effect on the current efficiency when several of the impurities were present in the electrolyte.
A Study Of The Composition Of Zinc Complex Cyanide Solutions By The Conductometric Method, Robert James Woody
A Study Of The Composition Of Zinc Complex Cyanide Solutions By The Conductometric Method, Robert James Woody
Bachelors Theses and Reports, 1928 - 1970
As the method or analysis used up to the present time has failed to give quantitative results in determining the composition of zinc cyanide baths, conductometric methods were adopted in this study. Supplementary tests were also carried out in this investigation.
Bird Studies Of The Bear River Marshes, Ernest W. Parkinson
Bird Studies Of The Bear River Marshes, Ernest W. Parkinson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The establishment of the Bear River Bay Bird Refuge has created for the state of Utah an immense and valuable biological field, a veritable paradise for naturalist and sportsman alike. The naturalist wants a place to study wild life and the sportsman desires game. With the proper control of open seasons on wild fowl the hunting instinct and incentive for the sport should be satisfied for the sportsman. To the naturalist this region will open up bountiful treasures of knowledge that is to be gained only by intense and prolonged scientific study.
Egyptian Mathematics, Evelyn Williams
Mathematical Instruments, Marguerite Massey
Mathematical Instruments, Marguerite Massey
Theses & Honors Papers
The selection of a subject for my honors work was determined not only by the desire to gain a broader knowledge of mathematics but also to make a study of something that would be of value in teaching in the state. From a variety of possible topics, the one, mathematical instruments seemed most interesting and appealing. This broad subject had to be narrowed down and made more specific. It was decided to limit it mainly to those instruments which might be used in the teaching of mathematics, these falling into two groups, those which can be made and those which …
