Determination Of The Solubilities Of Lithium, Sodium, And Potassium Sulphates In Absolute Methyl And Ethyl Alcohols, Jennie Lynn Lenox Jan 1922

Determination Of The Solubilities Of Lithium, Sodium, And Potassium Sulphates In Absolute Methyl And Ethyl Alcohols, Jennie Lynn Lenox

Masters Theses

"It was thought by the author that there might be some relation between the solubility of a salt in the alcohols and the position of those alcohols in the series of monohydric alcohols; that is, that there should be a definite increase or decrease in the solubility of any particular salt in going from a higher to a lower alcohol. The object of this paper was to find the solubilities of some simple salts in as pure alcohol as could be prepared, and to find any relationships if possible"--page 2.

The Preparation Of Zinc Chloride From Smelter Waste, Victor K. Fischlowitz Jan 1921

The Preparation Of Zinc Chloride From Smelter Waste, Victor K. Fischlowitz

Masters Theses

"Interest in the matter of recovering zinc from residual material attaches through the value of a practical method of recovery consistent with commercial operations. The material used in this work at the Missouri School of Mines and Metallurgy was supplied by one of the large chemical firms of Saint Louis"--Introduction, page 3.

Furfural (Furfuraldehyde) And Some Of Its Derivatives, Marion Smith Badollet Jan 1921

Furfural (Furfuraldehyde) And Some Of Its Derivatives, Marion Smith Badollet

Masters Theses

"In the spring of 1919 the Eastman Kodak laboratories suggested to the chemistry department of the Missouri School of Mines and Metallurgy that experiments on small-scale production of furfural be undertaken. After a series of experiments a small amount of this product was made and a report was given before the American chemical Society at St. Louis in April 1920. The furfural prepared at the Missouri School of Mines and Metallurgy was sold to the Eastman Kodak laboratories. Within recent years very little experimental work has been done on furfural. It commands a high price as only small amounts are …

The Action Of Nitrogen Trioxide On Pinene, Ernest Wayne Rembert Jan 1921

The Action Of Nitrogen Trioxide On Pinene, Ernest Wayne Rembert

Masters Theses

"The action of nitrous acid on pinene was first studied by Pesci and Bettelli in 1885. they obtained an oil, which, when treated with NH₄OH and steam distilled gave a product of the formula C₁₀H₁₆NO₂. At this point the investigation was discontinued. It is the purpose of this work to show the true mechanism of the reaction and also to establish the formula and nature of the products obtained"--Introduction, page 3.

The Preparation And Physical Properties Of Benzene- And Toluene-Sulphonamides, Karl K. Kershner Jan 1920

The Preparation And Physical Properties Of Benzene- And Toluene-Sulphonamides, Karl K. Kershner

Masters Theses

"The formation of sulphonamide derivatives is often of distinct importance. These substances are easily purified and give sharp mepting points which make them of value for identification phases of research work. Also they are of value commercially as in the production of saccharin and other similar compounds. The purpose of this investigation is to secure information on the comparative production and yield of sulphonamides, and intermediate products, formed from their respective ring hydrocarbons, as benzene and toluene. careful melting point are taken on purified products and solubility curves developed for different solvents. The latter give an interesting basis for comparison"--Introduction, …

Chemical Control Work In The N. K. Fairbanks Factories, John Whittlesey Bodman Jan 1917

Chemical Control Work In The N. K. Fairbanks Factories, John Whittlesey Bodman

Professional Degree Theses

"We propose to discuss in this thesis the organization of the N. K. Fairbank Company, particularly with reference to the duties of the Chemical Division, Operating Department in this organization. From a broad viewpoint, we believe that the particular organization by with the N. K. Fairbank Company secures application of its chemical ability to manufacturing operations as well as to special problems, is characteristic of a widespread movement taking place for recognition of the chemical engineer in industry. This is particularly true in those industries where manufacturing operations are based primarily upon practical applications of chemical principles"--Abstract, page 1.

The Decreasing Of City Garbage And Sewage Sludge, O. Henry Babcock Jun 1916

The Decreasing Of City Garbage And Sewage Sludge, O. Henry Babcock

Bachelors’ Theses

At the present time there seems to be no general solution of the problem of garbage and sewage sludge disposal, and the chances are that there never will be. The problem in each city is different so that no set rule can be given that will apply to every city. Therefore it is an original problem with each city, governed by cer­tain conditions existing there.
