A Study Of Hydrogen Bonding, Mary Ann Conklin

Theses

The proton magnetic resonance technique lends itself to the study of hydrogen bond equilibria. Through PMR spectra, hydrogen bonding can be detected. The specific proton which participates intimately in the hydrogen bond may be identified. The following work has investigated hydrogen bonding systems in which the proton donor is trifluoroacetic acid and the proton acceptor is an N-heterocyclic base, such as quinazoline, quinoline, and isoquinol ine. From measurements of the chemical shift versus concentration, and from measurements of the line width at half peak amplitude versus concentration for the time average exchange signal, the extent of hydrogen bonding may be …

Heat Transfer Between A Turbulent Round Jet And A Segmented Flat Plate Perpendicular To It, John Edward Chamberlain

Theses

Heat transfer between a room temperature, turbulent round jet and a segmented flat plate perpendicular to it has been investigated.

The heat transfer surface consisted of invar rings insulated from each other with silicone rubber. The source of heat was steam at atmospheric pressure condensing on the back of the heat transfer surface.

Since data were taken over a wide range of vertical distances between the nozzle and the flat surface both the potential cone and the fully developed regions of the jet were observed interacting with the heated plate.

It was determined that two modes of heat transfer occur; …

Analysis Of The Performance Of The Pressurized-Water Nuclear Reactor By Electrical Simulation - Analog Computer, Philip Bartells

Theses

This thesis demonstrates a method of analog simulation of a Pressurized-Water Reactor (PWR) using simplified techniques. The simulation is for the reactor vessel and is patterned after the "Yankee," the PWR owned and operated by the Yankee Atomic Electric Company of Rowe, Massachusetts, and built by the Westinghouse Corporation of Pittsburgh, Pennsylvania. The entire analysis is based on the one group model (postulated that neutrons in the reactor are of one energy). The areas analyzed are: 1. Reactor kinetics - one delay group 2. Temperature effects on reactivity A. Fuel temperature coefficient B. Moderator and coolant temperature coefficient. 3. Control …

Approximation Of Reaction Rate Models, Hsu-Tung Lee

Theses

In reaction rate studies, experimental data is interpreted and correlated in terms of various mathematical models. The converse of the modeling of practical problems is the task- of experimental determination of reaction mechanisms. Generally, this approach is classified into integral and differential methods. Both involve trial and error techniques. The mathematical model which satisfies the test becomes the equation for mechanistic representation.

Both the integral and differential methods have been tried. Generally speaking, the differential method is more advantageous than the integral. For one thing, the parameters which are involved in the nodal can be determined directly by the differential …

The Measurement Of Dispersion Coefficients, John Harold Rosenberger

Theses

This work describes a method of determining axial dispersion coefficients in a packed bed chemical reactor. This is done by measurement of the fractional conversion of acetic anhydride to acetic acid, by first order reaction in dilute solution. The reaction is carried out at various flow rates in a four inch diameter reactor packed with one-half inch Raschig rings. analysis is by the aniline-rater method. Calculation of the dispersion coefficients is by trial using a digital computer. The results are presented graphically and compared to results obtained by other methods. The results of this study are found to correspond to …

Heat And Mass Transfer In The Absence Of Air, James Joseph Howley

Theses

The effects of heat and mass transfer across a frosted heat exchanger operating in the absence of air was evaluated. It is felt that this work could be applied to processes such as desalination of water or the purification of materials by reverse sublimation.

The system consisted of a single 1/2” O.D. stainless steel tube mounted within a 3" O.D. plexiglas tube with the ends suitably flanged. A vacuum was maintained in the annular space. Refrigerated ethylene glycol passed through the inner tube in laminar flow. A series of runs with substantially air-free water vapor added to the annular space …

Thermal Conductivity Of Mixtures, Paul Joseph Orosz

Theses

A concentric cylinder type cell was designed and constructed tp measure thermal conductivity of liquids. The materials of construction were stainless steel and teflon, so that a wide variety of liquids could be tested.

The systems studied were aqueous solutions of methyl alcohol, ethyl alcohol, n-propyl alcohol, isopropyl alcohol, and tertiary-butyl alcohol. Thermal conductivity was studied as a function of composition.

The data obtained were fitted to quadratic equations by least squares analysis. For each system, an equation of the following type was obtained:

k_L = A + Bx_A + Cx_A²

where k_L is thermal …

Natural Gas Liquefaction, Travis George Hutchinson

Theses

In this thesis the author has developed a new process by which natural gas is converted into its liquid form. This has been accomplished by cryogenically cooling, condensing and fractionating natural gas. Resultant from this process is the design of natural gas liquefaction with valuable by-product recovery.

Reactions Of Cyanides With Borazines, Lawrence Meehan

Theses

B-trichloro-N-trimethylborazine in a dry tetrahydrofurane solution was reacted with potassium cyanide,, and sodium cyanide. On analysis of this reaction mixture, the precipitate was shown to contain both potassium chloride, and potassium cyanide when reacted with- the potassium cyanide, and sodium chloride and sodium chloride when reacted with sodium cyanide. On repeated runs of these reactions, it was shown that the precentages of the chloride to cyanide was approximately the same.

Case History Of A Test Pile Program For The Redevelopment Of Newark Airport, Patrick De Michele

Theses

A pile load test program was conducted at Newark Airport to determine the most economical piles to be utilized to support the structure in the Redevelopment of Newark Airport. The controlling criteria were the pre-determined design capacity of 50 to 100 tons for the piles and conformance to the Newark Building Code regarding the maximum allowable loads on the Airport's bearing strata and the allowable settlements for test loaded piles. Thirty-four piles, ten timber, four steel H-piles, four pre-stressed concrete, seven cobi shell and nine steel pipe piles, were driven to determine driving characteristics of the piles and the reaction …

The Frequency Response Analysis Of A Reboiler-Condenser Under Condensate Control, Douglas F. Ready

Theses

In this investigation, the dynamics of a reboiler-condenser pair, with the reboiler operating under condensate control, were analyzed both theoretically and experimentally, and the results of the two analyses compared.

The theoretical analysis was performed using the standard method of Laplace transform transfer function synthesis.

The experimental study consisted of a frequency response analysis of the system response to sinusoidal variations of the steam condensate rejection rate.

Two mathematical models were developed, one quite rigorous but extremely cumbersome, the other neglecting all but the most important factors for the sake of simplicity.

The experimental data (in the form of Bode …

Potassium T-Butoxide-Initiated Elimination On Substrate 1,1,2-Trimethoxyethane, James Waldron

Theses

1-bromo-2,2-dimethoxyethane (I) was prepared in 68% yield from the addition of bromine to a solution of vinyl acetate and methanol. A Williamson ether synthesis, using sodium methoxide in methanol and I, gave 1,1,2-trimethoxyethane (II) in 48% yield. The compound (II) was the desired substrate for elimination reactions because it contains poor leaving alkoxide groups.

Many different reactions were investigated to convert II into 1,2-dimethoxyethylene. Among these were pyrolysis, acid catalyzed eliminations, and base initiated elimination reactions.

Best results were obtained using a bomb reactor, compound II as substrate, and potassium t-butoxide as the base. From this reaction, tertiary-butyl methyl ether, …
