A Study Of The Miscibility Of Various Liquids With Ethylene Glycol, Joseph J. Furlong

Bachelors’ Theses

Ethylene glycol is a compound possessing great interest, both from a theoretical and a practical standpoint. In its properties it lies midway between ethyl alcohol, C₂H₅0H, and glycerol, C₃H₅(0H)₃, the three compounds together forming an homologous series of alcohols.

A few years ago this substance was a scientific curiosity, produced solely by laboratory methods, and without any commercial value, although it had been known for more than sixty years. Today the manufacturers cannot produce enough glycol to satisfy the growing demand. The DuPont organization wanted to use it in a …

A Study Of Halowas Oil In Reference To Its Properties And Uses, Joseph F. Hoffman

Bachelors’ Theses

Halowax oil, specific gravity 1.25, is a thinly fluid mobile liquid, almost colorless, having a characteristic odor which is not unpleasant, heavy, or persistent. It is manufactured by the Halowax Corporation, a division or the Bakelite Corporation, at Wyandotte, Michigan.

The Corrosion Prevention Qualities Of The Aldehydes, Oliver R. Mackenzie

Bachelors’ Theses

In preparing the natural ore of iron for commercial use, man has met with great success. At present, approximately 36,000,000 tons of steel are produced yearly in the United States alone. Man, however, has been confronted by an unceasing, tireless agent which tends to return the newly manufactured steel to the oxide of the iron, a condition similar to that of the natural ore. To prevent this action, man has put up a continual fight, using many preventitlves, but to date corrosion has overcome all of man’s contrivances and emerged the winner.

The Study Of The Effects Of Different Metallic Soaps On The Water Content Of Water-In-Gasoline Emulsions, Lynn D. Wilson

Bachelors’ Theses

The study of emulsions and emulsification is of very great theoretical and practical interest. From the standpoint of pure science it throws much light on the problems of surface tension, surface concentration, absorption, surface films, electrical double layers. Brownian movement, and the general theory of disperse systems and colloids. It is also of importance in biological science, e.g., the adsorption of fats and the permeability of membranes. When industrial and applied science are considered, it is remarkable how many subjects of interest and importance are dependent on a knowledge of the formation, behavior, and stability of emulsions. In this connection, …

A Study Of Various Metallic Electrodes In Potentiometric Titrations, Louie Boncyk

Bachelors’ Theses

The significance of ion concentrations has been the subject of many investigations during the last few years. The results obtained have demonstrated without question the unlimited possibilities existing for laboratory and industrial applications of ion concentration measurements. It has been shown in many instances biological activity, fermentation, and filtration are influenced to a large extent by variations in the H-ion concentration. In addition, the way is open for improved control and accuracy in the many neutralization problems encountered in the laboratory. The lack of suitable electrodes has greatly retarded the practical applications of H-ion measurements to plant industrial problems. The …

The Amount And Identification Of Amyl Alcohols In A Commercial Mixture Of Pentanols, M. Eugenia Eberhard

Bachelors’ Theses

Casing head gasoline obtained from natural gas yields five commercial products. One of these is a mixture of amyl alcohols. As treated by the Sharples Company, West Virginia, pentane is separated and treated with chlorine. Three chlorine derivatives are produced. These are treated with caustic soda and may f'orm eight possible amyl· aloohols~1 The products of the normal pentane, only, are the subject matter of this thesis.

Iron And Cobalt Salts As Catalysts In The Oxidation Of Sodium Sulfite By Free Oxygen, Loren C. Bryner

Theses and Dissertations

The present investigation was carried out to show the catalytic effect of some iron and cobalt salts on the oxidation of sodium sulfite solutions by free oxygen. The rate of reaction was determined by measuring the volume of water required to replace the absorbed oxygen. A photograph and diagrammatical arrangement of the apparatus is given, (Page 14). From the preliminary experiments it was found that the rate of oxidation of sodium sulfite solutions is dependent upon concentration, and speed of the shaker.

Revision Of The Jefferson City Formation In The Rolla Quadrangle, James Shelley Cullison

Masters Theses

"The geology of the Rolla quadrangle was mapped by Lee in 1912. At that time all the dolomitic strata above the Roubidoux and beneath the Carboniferous formations in this area were placed in the Jefferson City. A more detailed study of the stratigraphy of the whole Ozark region by Ulrich has shown that some of the strata which had been included in the Jefferson City formation on lithologic grounds are not equivalent to the dolomites in the type section at Jefferson City, Missouri"--Introduction, page [1].

The Chromite Deposits Of Stillwater And Sweetgrass Counties, Montana, Uuno Sahinen

Bachelors Theses and Reports, 1928 - 1970

In writing this report, two objects were kept in mind, (1) to explain, if possible, the origin of the chromite deposits found in Sweetgrass and Stillwater Counties, and (2) to bring up to date all information on these deposits which had thus far been available.

The work done consisted of study of the rocks and ores of the area under the microscope, both as thin sections and as polished sections, practically all of which was done at the Montana State School of Mines, during the school year of 1928 - 1929.

The rock specimens and much information as to their …

The Constant Of Torsion Of A Given Wire, Ella M. Blunk

Bachelors’ Theses

"Using a given wire, the value of n determined dynamically is generally somewhat larger than the value determined by statical method. This is due partly to the fact that a wire, under the action of a torque, does not at once acquire its final twist. The twist increases under the application of a constant torque; and therefore, during a brief application of the torque (for example, during an oscillation of heavy body attached to the wire) the torque per unit twist has larger value than when the torque is applied for a long time. " Edwin Edser

A Study Of The Official Methods Of Analysis For Determining The Availability Of Nitrogen In Fertilizers, Raymond A. Schmidt

Bachelors’ Theses

The Milwaukee Sewage Disposal Plant is unique in that it has successfully met the engineering and chemical problems encountered in putting the theories and ideas of the simple experimental station into operation on a large scale. Municipal sanitation was the aim of the plant. It has accomplished its purpose and has been operating several years with a high degree of efficiency and low per capita cost. The plant will be called upon to take care of the sanitary needs of Milwaukee for many years to come.
