Fugacity And Activity Coefficients For Methane-Carbon Dioxide System, Robert J. Capik

Theses

The Redlich and Kwong equation of state has been used along with the method derived by H. C. Van Ness (18) to calculate the fugacity and activity coefficients of the components of the methane-carbon dioxide system. Calculations have been carried out for the pure gases and four mixture compositions at 160°F. and 280°F. with pressures up to 600 atmospheres.

The method of Van Ness was used because it offered an accurate and simple way of calculating the fugacity and activity coefficients. This is accomplished by a combination of analytical and graphical procedures in which the graphical error is minimized by …

Alkylation With Some Alkyl Borate By The Friedel-Crafts Methods, Richard Ernest Huber

Theses

Normal butyl, allyl, methylbutyne and 2-chloroethyl borates were synthesized in yields above 90.0% from their corresponding alcohols and boric acid. Using some of the above alkyl borates, and others commercially available, as alkylating agents, benzene was alkylated by the Friedel-Crafts method, using aluminum chloride as the catalyst. Yields were dependent on catalyst concentration. The alkyl benzenes were identified by means of: 1) physical constants, 2) infrared spectra, 3) melting points of derivatives, and 4) chemical analysis. Starting with normal alkyl borates, the formation of isomeric and dialkylated products was established through the analytical data.

Collection Of Germanium From Acid Etch Waste By Ion Exchange, Robert Welsh Meyler

Theses

This report is an investigation of the use of ion exchange resins to recover germanium from acid etch wastes encountered in transistor manufacture.

Most of the experiments were performed with acid etch waste of unknown germanium content. The object was to determine if the ion exchange technique were applicable, and to select the most practical operating procedure.

When a satisfactory procedure had been established, later experimental runs were made with an acid etch solution of known germanium concentration to determine the yields of recovered germanium.

Yields of 60 per cent to 75 per cent recovery of germanium from the etch …

Vapor Liquid Equilibria Of Diacetone Alcohol In Various Solvents, John A. Mulligan

Theses

This paper presents the initial study of vapor-liquid equilibria data for the systems (a) diacetone alcohol-methanol (b) diacetone alcohol-ethanol and (c) diacetone alcohol-benzene at 100mm and 200mm and confirms the data reported by Hack and Van Winkle (6) on the system (d) diacetone alcohol-water at the same pressures. Margules and Redlich and Kister constants have been determined from the data, and are presented for use in future studies.

A comparison has been made between Redlich and Kister constants determined from laboratory data, and Redlich and Kister constants predicted from the physical properties of the components. Redlich and Kister constants predicted …

Enthalpies And Partial Molal Enthalpies For Methane-Carbon Dioxide System, Isaac Pass

Theses

Enthalpies and partial molal enthalpies have been calculated by a combination of analytical and graphical procedures for the methane carbon dioxide binary system at 160°F, and at pressures from 200 to 9000 psia.

Mixtures containing .0852, .19912, .3583 and .6685 weight fraction of methane in carbon dioxide, as well as the pure components were used. The method for calculation of the enthalpies was outlined by Van Ness (1) and involves the application of residuals to the Redlich-Kwong equation of state (2).

The results of this paper illustrate the value of the method as an accurate and reasonably convenient tool. Excellent …

Identification Of Inclusions In Armco Ingot Iron By The Use Of Polarized Light, Carl A. Plate

Bachelors Theses and Reports, 1928 - 1970

It is the author's hope that by systematically investigating the inclusions in ingot iron and comparing their specific properties with the properties of substances known to exist as inclusions, a rapid and accurate method may be found to identify them using a polarizing microscope. Where possible photomicrographs will be used to illustrate the results obtained so that the reader may obtain a better picture of the effects produced by polarized light.

An Investigation Of The Fundamental Factors Affecting The Green Ball Characteristics In Pellet Formation, Thomas J. Wright

Bachelors Theses and Reports, 1928 - 1970

The purpose of this investigation is to determine the relative effects on the quality and characteristics of the pellets. Once the major factors effecting agglomerating materials are understood, formerly poor and nonagglomerating materials may be affected so that they will produce good quality agglomerates. Should the factors prove difficult to vary or impossible at least they may be identified and understood, thus serving as a guide for further attack or judgment in overall process design.

The Effect Of Thermal Treatment On The Engineering Properties Of Clays, George R. Laughlin

Kentucky Transportation Center Research Report

Of the cohesive soils the property of plasticity is usually of the most concern to the engineer. The clay minerals rather than the clay size material present in a soil determine the degree and magnitude of plastic properties. In turn, the plasticity of the clay minerals varies according to their mineralogy and particle size. Of the various types of clay minerals present in a soil, only kaolinite, illite and montmorillonite occur in sufficient abundance to be of general engineering significance.

Much prior work has been performed to alter these plastic properties of clay soils. This has been accomplished in some …

The Volumetric Analysis Of Nitrocompounds Using Chromous Chloride, Charles Caslin Jamison

Theses

Chromous chloride has been shown to be more efficient than titanous chloride in the reduction of refractory nitro and nitramine groups in both aromatic and aliphatic compounds.

It was found that concentrated hydrochloric acid increases the efficiency of chromous chloride to a point where it would reduce the most difficult to deduce nitro-campounds.

The compounds studied were p-Nitromethylaniline, 2,4-Dinitrotoluene, 2,4-Dinitroaniline, 2,4,6-Trinitrotoluene, Nitroguanidine, I,9-Di4cetoxy-2,4,6,8-penta-methylenetetranitramine, Sym-Cyclotrimethylenetrinitrimine, and Sym-Cyclotetramethylenetetranitramine.

Separation And Concentration Of Stibiconite, William Howard Painter

Bachelors Theses and Reports, 1928 - 1970

Primarily, the purpose of this study is to separate stibiconite from associated gangue minerals. The ore containing antimony, as an oxide stibiconite, occurs in Mexico and its benefication would be an advantage to the mineral resources of that country. While the deposit from which this ore is derived is American owned, the resource is presently non-economic. A concentrate must be derived of suitable grade for its use in a smelting operation and from which metallic antimony would be produced.
