A Study Of The Heat Effects At Electrodes During Electrolysis, Howard Frank Holmes Dec 1958

A Study Of The Heat Effects At Electrodes During Electrolysis, Howard Frank Holmes

Doctoral Dissertations

Temperature difference measurements were made during the electrolysis of aqueous copper sulfate between copper electrodes. The temperature differences measured were those between the cathode and the anode, the cathode solution, and the anode and the solution. These values were obtained as a function of the time of the electrolysis. The variation of these differences with time and their magnitudes were explained in terms of the entropy changes occurring at the electrodes, resistance, and polarization.

The effect of some inert electrolytes on these temperature differences was determined as was the effect of gelatin. Explanations for these effects were given in terms …


Synthesis Of 7-(Dialkylaminoalkyl)-Benzo [C] Phenothiazines; The Metalation Of 7h-Benzo [C] Phenothiazine With N-Butyllithium, William Earl Tatum Dec 1958

Synthesis Of 7-(Dialkylaminoalkyl)-Benzo [C] Phenothiazines; The Metalation Of 7h-Benzo [C] Phenothiazine With N-Butyllithium, William Earl Tatum

Doctoral Dissertations

Introduction: Phenothiazine is one of the more widely investigated heterocyclic molecules known to modern chemistry. The founding of the synthetic dye industry in the latter part of the nineteenth century stimulated many new fields of organic research, one of which was phenothiazine chemistry. Bernthsen, known as father of phenothiazine chemistry, first synthesized (1) this compound in 1883, after suspecting its presence in the nucleus of the methylene blue dyes.

Since that time phenothiazine and its derivatives have found uses as antioxidants (2), antihistamines (3), antiemetics (4), and in the treatment of Parkinson's disease (5). During the past decade, considerable attention …


A Study Of The Reduction Of Certain 1-Substituted Naphthalenes By Alkali Metals In Liquid Ammonia, Gerald Titus Davis Dec 1958

A Study Of The Reduction Of Certain 1-Substituted Naphthalenes By Alkali Metals In Liquid Ammonia, Gerald Titus Davis

Doctoral Dissertations

(From the Introduction)

The first phase of the work to ·be presented was aimed at studying the conditions under which 1-aminonaphthalene is efficiently reduced to the 5,8-dihydro derivative and thereby finding experimental evidence which would be of value in the selection of a mechanism for the reduction. After the initial work, the study was extended to include the reduction of other 1-substituted naphthalenes.


Spectral Theory Of Self-Adjoint Ordinary Differential Operators, Charles C. Oehring Dec 1958

Spectral Theory Of Self-Adjoint Ordinary Differential Operators, Charles C. Oehring

Doctoral Dissertations

Introduction: Many of the properties of the ordinary Fourier series expansion of a given function are shared by the orthogonal expansion in terms of eigenfunctions of a second order ordinary differential operator. Let p = p(x) and q = q(x) be real-valued functions such that p, p', and q are continuous, and p(x) > 0, on a finite interval a ≤ x ≤ b. Let λ be a complex parameter. The classical Strum-Liouville theory [9, section 27; 4, Chapter 7; 21, Chapter 1]1 is concerned with solutions of the differential equation -(py') + qy = λ, which satisfy certain real …


A Spectrophotometric Study Of The Analytical Chemistry Of Vanadium, Kenton E. Bentley Nov 1958

A Spectrophotometric Study Of The Analytical Chemistry Of Vanadium, Kenton E. Bentley

Chemistry and Chemical Biology ETDs

Vanadium is most frequently encountered in analytical chemistry in the volumetric determination of vanadium by oxidation-reduction titration. Vanadium is rarely determined gravimetrically and finds little use as a reagent in gravimetric analysis. The simple ionic forms of the valence states of vanadium and the colors of acidic, aqueous solutions of these ions, as reported in the literature, are listed in Table 1. There is some confusion in the nomenclature of the ionic forms; that given in Table 1 is by analogy to chromium.

The Synthesis Of Some Triazole Derivatives, John M. Collier Nov 1958

The Synthesis Of Some Triazole Derivatives, John M. Collier

Chemistry and Chemical Biology ETDs

The triazoles have been known since the late 1800's when von Pechmann discovered the ring system during the course of his work with osazones. He first assigned the name "osotriazone" to the parent ring; this was later changed to "osotriazole", a name which is still retained for certain derivatives obtained from the sugar osazones.

The Synthesis Of Some Fluorine Derivatives As Potential Scintillation Solutes, Martin Dennis Barnett Oct 1958

The Synthesis Of Some Fluorine Derivatives As Potential Scintillation Solutes, Martin Dennis Barnett

Chemistry and Chemical Biology ETDs

In connection with work being carried out, in part, by the Biomedical Research Group, Los Alamos Scientific Laboratory, on the evaluation of organic compounds as solutes in liquid scintillation detector systems, it seemed of interest to investigate the liquid scintillation properties of fluorine analogues of p-terphenyl and p-quaterphenyl. These compounds have been shown to possess remarkable scintillation properties; however, the use of p-quaterphenyl has been severely curtailed by its low solubility in toluene. Accordingly, the synthesis of a number of 2- and 2,7-substituted fluorines was carried out in an effort to obtain a more soluble, completely conjugated aromatic system and …
