A Suggested Method For The Measurement Of Unsaturation In Organic Compounds By Means Of A Hydrogen Number, Richard Roberts May 1943

A Suggested Method For The Measurement Of Unsaturation In Organic Compounds By Means Of A Hydrogen Number, Richard Roberts

Bachelors’ Theses

The measurement of unsaturation in organic compounds are commonly expressed in terms of an iodine number, but as this value is not trustworthy in a number of cases, it has been suggested by earlier worker that an indication of unsaturation could be obtained by the quantitative hydrogenation of a compound and expressing the result in terms of a hydrogen number. Although such determinations have been previously made, usually at elevated temperatures and pressures, it is the purpose of this work to carry out the hydrogenation at room temperature and atmospheric pressure. For purposes of comparison, determinations will be made at …

Permeability And Porosity Studies Of The Cut Bank Oil Sand, Wesley Edward Davis Apr 1943

Permeability And Porosity Studies Of The Cut Bank Oil Sand, Wesley Edward Davis

Bachelors Theses and Reports, 1928 - 1970

In studying the Cut Bank field and its numerous wells, it is found that dry holes are surrounded by producing wells, and also that the field as a whole is very irregular; water, oil, and gas zones in many cases following no definite pattern. In some instances, this phenomenon may be due to the lensing and thinning of the producing sands, but it is evident that this is not the only factor. There­fore, the controlling factors must be porosity and permeability.


Coal In Montana, Clifford A. Barkell Apr 1943

Coal In Montana, Clifford A. Barkell

Bachelors Theses and Reports, 1928 - 1970

Coal was first mined in Montana in the year 1880. For the last thirty years the mining of coal in this state has been very important-with few people realizing its value. In the mineral industry, the value of the annual production of coal is exceeded by none of the non-metallics, and only by gold, silver, and copper in the metallics. At the present time the coal production of Montana is valued at about 41000,000.00 annually.


Zinc Plating Magnesium, Howard Wilbur Adam Apr 1943

Zinc Plating Magnesium, Howard Wilbur Adam

Bachelors Theses and Reports, 1928 - 1970

Magnesium and magnesium alloys are becoming more and more important in modern industry.

An Investigation Into The Recovery Of Indium From Fume Residue, Emery J. Turner May 1942

An Investigation Into The Recovery Of Indium From Fume Residue, Emery J. Turner

Bachelors Theses and Reports, 1928 - 1970

Several months were required to produce a single gram of indium. Consequently, the industrial history of the metal is extremely short. In view of the unique properties that indium has demonstrated in this short period, it is probable that indium is still in its early stage of development. However, the commer­cial applications of the metal are well established and indium is now produced on a commercial scale. It is obtainable as the metal or in solution for electroplat­ing.
