This thesis describes the procedures used in preparation of the derivatives of certain alkyl phenylacetates and the necessary intermediate compounds. Compounds resembling the structure of Benadryl were prepared in this study in the hope that at least one might prove to be of value in the fight against allergy.

This investigation was limited to the preparation of substituted phenoxyacetic acids and related compounds. The types of substances prepared for testing can, in general, be placed in three groups. These are: aryloxyacetic acids, arylmercaptoacetic acids, and those acids containing the thiophene nucleus.

This thesis discusses the preparation of a-(o-nitro-p-methylphenylmercapto)-acetophenone by the reaction between acetophenone and o-nitro-p-methylbenzenesulfenyl chloride in boiling chloroform. The use of stannous chloride in glacial acetic acid for the reduction of nitro groups to amino groups was found generally satisfactory in spite of the difficulty often met with in isolating the amino product.

This thesis describes attempts to synthesize 5-allyl-5-(2-thienyl)-barbituric acid as an improved anticonvulsant.

The work encompassed by this thesis is partially a reproduction of the results obtained by John A. Marcia in his work on the photo-chemical reactions of branched hydrocarbons. The previous work done on this particular problem was rendered partially valueless because of the loss of the liquid hydrocarbon product when a fractionation column at the Texas Company Laboratory, Beacon, New York, broke during the fractionation run.

It was decided to determine whether or not 2,2,3-trimethylbutane could be formed by the photochemical reaction of isobutane and propane in the presence of mercury vapor energized by ultraviolet radiation from a mercury vapor lamp.

This thesis is a study of the synthesis of N-substituted di(2-thienylmethyl)acetamides.

This thesis describes the synthesis of a series of 5-alkyl-5-(2-thienylmethyl)-barbituric acids.

This thesis describes a fractionation column method of separating isobutane and isobutene to isolate isooctane.

This study was made in an attempt to analyze qualitatively the reaction products formed when chlorosulfonic acid reacts with 2, 2, 4-trimethylpentane.

This study investigates the rate of reaction of various types of hydrocarbons with chlorosulphonic acid at the temperature 10 degrees Celsius.

The object of this paper is to determine the optimum concentration of sulfur dioxide to be used in the commercial dehydration of the sweet potato by this process. Attention has been given to two aspects of the problem, (1) the effect of sulfur dioxide upon the extraction of water from the sweet potato by mechanical means, and (2) the effect of sulfur dioxide upon the stability of the carotene in the sweet potato over a period of several months.

The object of this paper is to compare the Tennessee green pod pole bean with other beans as to chemical composition and food value.

The water which supplies the city of Henrietta, Clay County, Texas, is obtained from the Little Wichita River. A concrete dam was built across the river at a point about a mile and a half north of town.

Evidence indicates that the sorghums were grown as cultivated crops in Egypt as early as 2200 B. C. The sorghums are native to Africa, but indications are that they may have evolved independently in India.

The purpose of this experiment was to determine the value of sulphur dioxide as a dehydrating agent for sweet potatoes.

This study is an attempted synthesis of dithienyl barbituric acid.

A study of the effect of photo-sensitized mercury on mixtures of isobutane and isobutene.

The purpose of this investigation is to determine the suspended organic matter and the total phosphorus in the waters of Lake Dallas and to evaluate these findings. Since organic matter floating in lakes is largely composed of minute plants, animals, and detritus derived from animals and plants, the fertilizing effect of phosphorus must be considered as an integral part of this problem.

This thesis describes three separate and unrelated chemical experiments. The first investigates analogs for the compound DDT. The second investigates the properties of O-substituted hydroxylamines. The third investigates the action of slight changes to the structure of an antihistaminic agent.

This thesis describes the synthesis of a series of dialkylaminoalkoxy derivatives of methyl p-nitrophenylacetate for testing as anti-histamine or hay fever drugs.

This thesis deals with the preparation of dialkylaminoalkoxy derivatives of p-chlorophenoxyacetic acid and phenylacetic acid.

Although many sympathomimetic amines have been prepared, the perfect one has not yet been made. Chemists are still attempting to synthesize a selective drug with more prolonged effects and free from side reactions or compensatory vasodilation. With this idea in mind it seemed feasible to prepare a group of O-substituted hydroxylamines.

Lignite is a low grade of coal widely distributed throughout the world. A complete analysis of lignite has not been made, due to the difficulty encountered in the separation of the complex organic compounds bonded therein.
