The Fluorine And Manganese Content Of Certain Missouri Waters, Erwin Charles Hoeman

Masters Theses

"Since early in 1931, considerable attention has been brought to bear upon the subject of fluorides in drinking water supplies, following the discovery of high fluoride concentrations in waters consumed by persons afflicted with the dental defect known as mottled enamel. Analyses have been made, in the course of this study, of a comparatively large number of Missouri waters. The waters analyzed have been collected and made available by the Missouri Geological Survey and Water Resources. They have been secured from diverse sources and include surface waters and underground waters from different geological formations, throughout the State of Missouri"--Introduction, page …

The Study And Solution Of A Corrosion Problem Induced By Air Conditioning, Frederick William Hoertel

Professional Degree Theses

"A recent personal investigation conducted by the writer has disclosed the extremely interesting fact that almost every large air conditioning plant in operation in St. Louis is experiencing serious difficulty in operation due to corrosion of some component part. With the ever increasing number of installations of large air conditioning plants the problem of corrosion prevention is becoming one of major economic importance"--Introduction, page 7.

The Photobromination Of Azobenzene, Oden Cass Garst

Masters Theses

"The purpose of this thesis is to make a study of the photobromination of azobenzene. The effect of various variables has been studied. The factors considered were, temperature, frequency of light, and concentration. Information on photobrominations is of great scientific importance, as it opens up a comparatively new field of research, and also contributes further data which helps to establish the quantum theory, if indeed this theory is still in controversy"--Introduction, page 3.

A Study Of The Effects Of Paraffin Wax Upon The Viscosities Of Lubricating Oils, Charles Leo William Hunze

Masters Theses

"The determination of the mean molecular weight of oils and paraffin waxes may have significance as: (1) an important property from a purely research point of view; (2) a step towards structure determination; (3) a study of molecular association with viscosity, making possible the application of well established viscosity binary mixture formulas to oil blends and oil and paraffin wax blends; (4) an aid in the calculations of latent heats for refinery engineering purposes (see A.A. Ashworth's applications of this property); (5) a possible means for identifying bitumens of unknown origin, and determining the approximate proportion of each type in …

A Method For Increasing The Iodine Value Of The Saturated Fatty Acids, Richard Groves Holmes

Masters Theses

"The work covered by this thesis was undertaken with the idea of finding a method whereby unsaturated oils, of the drying type (those having iodine values of one hundred fifty or above), could be made from the saturated fatty acids. After an exhaustive search of the literature no evidence was found that this means of producing the unsaturated acids had ever been developed. Work has been done on the chlorination products of the fatty acids, the processes being covered by patents. No evidence however was given as to the possible structure of these compounds"--Introduction, page 1.

A Study Of The Evaporation Of Organic Liquids And Mixtures Of Organic Liquids, George Walter Eckert

Masters Theses

"The purpose of this thesis is to make a study of the evaporation of organic solvents. The relative rates of evaporation of the single substances and binary and ternary mixtures are to be considered. A study of the changes in composition of binary and ternary mixtures that occur on evaporation are to be made. Information on the evaporation of organic liquids is important in relation to lacquers, and for that reason the solvents used in this work are liquids commonly used in making lacquers"--Introduction, page 2.

The Relation Between The Mean Molecular Weight And The Absolute Viscosity Of Lubricating Oils, John Isler Moore

Masters Theses

"Of all the properties required of a good lubricant the most important is that of the viscosity at the temperature of its use. Most lubricants consist of oils blended or compounded together in such a way as to produce an oil of a desired viscosity, falling in the special group of viscosities expressed by the Society of Automotive Engineers in their tabulations.

There have been several methods developed to enable the refiner to blend quickly and efficiently although Bell stated that the methods were largely that of trial and error. Herschel formed a chart for blending by the logarithmic rule …

The Solubility Of Calcium Sulfate In Sodium Chloride Solutions, Edward Walter Mockobey

A Relationship Between The Mole Fractions And The Absolute Viscosities Of Blended Lubricating Oils, Ernest Reginald Epperson

Masters Theses

"The viscosity of binary liquid mixtures has been a subject of much investigation, but most of the work has been done with mixtures of substances other than lubricating oils. Lubricating engineers have found viscosity to be the most important property of a good lubricant, though up to the present time no one has succeeded in deducing a satisfactory expression by which the viscosity of a blended lubricant may be calculated from a knowledge of the physical properties of its components. This investigation has been an attempt to find a relationship between the absolute viscosity of a blended lubricating oil and …

A Study Of Some Methods Of Concentrating Uranium And Radium In Carnotite Ore, H. L. Gibbs

Masters Theses

"Carnotite ore is a source of radium and it is the recovery of this element which is chiefly sought in its treatment. The radium results from the radioactive disintegration of uranium which is one of the constituents of the yellow mineral carnotite. The ores are largely low grade. Higher grade pockets occur scattered in the deposits and because of their irregular occurrence are not easily located. The larger low grade deposits which are more easily accessible contain considerable quantities of calcium carbonate and oxide minerals. These cause a high consumption of the acid used in the chemical treatment of the …

Chemical Control -- Influence On Manufacture And Quality Of Cement, Joseph Owen Hunt

Professional Degree Theses

"Definition:- Portland cement may be defined as the product obtained by finely pulverizing clinker produced by calcining to incipient fusion an intimate and properly proportioned mixture of argillaceous and calcareous materials with no additions subsequent to calcination excepting water and calcined or uncalcined gypsum. While a review of Portland cement analysis would show a wide variation in chemical composition, it must not be supposed that such latitude in proportioning the raw material really exists. If the resulting Portland cement is to be sound, normal setting, and of good strength it is imperative that the raw materials shall be correctly proportioned …

Gas Analysis By Measurement Of The Thermal Conductivity, Bertie Lee Browning

Professional Degree Theses

"Types of gas analysis. Methods for the analysis of gases may be divided into two general classes, physical and chemical. In chemical methods, a constituent of the gas mixture undergoes chemical reaction and the amount of the constituent is determined by change in volume or by supplementary chemical methods such as titration. The physical methods of analysis differ in that no chemical change takes place in the gas. Instead, a determination is made of some physical property which is related to the composition of the gas mixture. Some of the physical properties which have been used for purposes of analysis …

A Qualitative Study Of Arsine And Stibine Reactivity Toward Inorganic Salts In Certain Solvents, John Edgar Antener

Masters Theses

"The effects of arsine and stibine on some substances have been investigated by various workers and recorded without any attempt at systematic classification. In this work a more comprehensive study of the precipitating effect of arsine and stibine on common inorganic salts in certain solvents, namely, water, ethyl alcohol, ethyl ether, acetone, carbon disulphide, carbon tetrachloride, chloroform, and benzene has been made, with an attempt at reactivity classification"--Introduction, page 1.

The Solubilities Of Alkali Chlorides And Sulfates In Anhydrous Alcohols, Emmet Rudolph Kirn

Masters Theses

"A search of the literature for data on the solubilities of inorganic salts in various anhydrous alcohols will show that comparatively little work has been recorded. Most of the work has been done on salts in aqueous normal alcohols and practically all of this data concerns only methyl and ethyl alcohols. This information shows a wide divergence in results with different workers. Perhaps these differences in data may be attributed to an error in that the alcohols may not have been absolutely anhydrous, for even small traces of water greatly affect the solubility of the salts. Again, the methods of …
