A Study Of The Fischer-Tropsch Synthesis, John E. Dornfeld Aug 1943

A Study Of The Fischer-Tropsch Synthesis, John E. Dornfeld

Bachelors’ Theses

In Continental Europe, where raw materials are at a premium, it is necessary to synthesize as much as possible. Hydrocarbons and their oxygenated derivatives are important for "everyday" life. When importation costs of raw materials are high, synthesis is necessary provided it can be done cheaper. The Fischer-Tropsch process is the answer for the needs of synthetic hydrocarbons and their oxygenated derivatives.

The purpose of this thesis is to obtain hydrocarbons and their oxygenated derivatives by the Fischer-Tropsch process in the wax range. From the literature it appears that no work in the industrial field is being done in the …

Construction And Use Of A Bingham Type Viscometer, Harold P. Bodenstab Jun 1943

Construction And Use Of A Bingham Type Viscometer, Harold P. Bodenstab

Honors Theses

Bingham in his book "Fluidity and Plasticity" has described a type of viscometer similar to the Ostwald visocometer but which has the added feature of a variable applied pressure. By changing the pressure the time of flow may be controlled so that a rather viscous liquid will not have an inconveniently long time of flow in a viscometer which in suitable for another liquid. The construction of such an apparatus consists in teh assembly of a special viscometer with an arrangement for applying air pressure, measurement of such air pressure, and the placement of the viscometer in a thermostat. Such …


A Study Of Some Cyclohexyl Tin Compounds, Donald J. Giroux Jun 1943

A Study Of Some Cyclohexyl Tin Compounds, Donald J. Giroux

Honors Theses

Although a large number of organotin compounds have been prepared (Dr. Garzuly lists over one hundred and fifty), comparatively little is known about them. It was the purpose of this investigation to study some of the cyclohexyl tin compounds with a view toward finding out more about their preparation and properties, and to prepare some that had not been prepared before. Unfortunately time and circumstances prevented the latter.


A Study Of The Co-Gelation Of Silica And Titania, Theodore Male Jun 1943

A Study Of The Co-Gelation Of Silica And Titania, Theodore Male

Honors Theses

Silica gels have been the object of extensive research. Titania gels have been the object of limited research, but they have been reported as made successfully. The most commonly used silicate solutions are basic and the titanium solutions are acidic. Acids are used to control the gelation of silicon, and bases are used to control the gelation of titania. The imagination is taxed only slightly in assuming as plausible the use of the acid titanate solution to control the gelation of silica and the basic silicate solution to control the gelation of titania, and thereby produce a mixed gel. If …


Scattering And Polarization Of Light By Silicic Acid Gel-Forming Mixtures, Donald Male Jun 1943

Scattering And Polarization Of Light By Silicic Acid Gel-Forming Mixtures, Donald Male

Honors Theses

Much work has been done on the factors affecting the time of setting of silicic acid gels. The effects of hydrogen ion concentration, heat, and the presence of ammonium chloride and other soluble impurities are quite well known. Work has also been done on the gels, during and after setting, on such properties as electrolytic conductivity, surface tension, syneresis elasticity, viscosity and the ability to scatter light. It is with this last property that this research is chiefly concerned. The oldest known law concerning optical properties of a collodial solution is Lamberts' law of absorption.


A Comparison Of The Time Of Set Of Similarly Constituted Gels At Various Temperatures, John E. Macdonald Jun 1943

A Comparison Of The Time Of Set Of Similarly Constituted Gels At Various Temperatures, John E. Macdonald

Honors Theses

This investigation was undertaken with the purpose of obtaining more data on the question of the existence of thermally reversible silicic acid gels, i.e., silicic acid gels which would reliquify on heating. Some work was done in the highly basic region at 21 degrees and 40 degrees. An attempt was made to use the Leads and Northrup glass electrode apparatus present in the Union College Chemical Laboratory which, however, failed, although Spittle using this apparatus, apparently met with some success. In order to obtain data on the change of time of set with temperature of gels having the same composition …


A Preliminary Investigation Of Certain Purine Thiocyanate Complexes, Gerhard W. Leubner Jun 1943

A Preliminary Investigation Of Certain Purine Thiocyanate Complexes, Gerhard W. Leubner

Honors Theses

The purpose of the work has been to attempt to prepare some compounds of the purine group with regard to their possible use in cardiotherapy. Some of the purine derivatives such as caffeine, theobromide, and theophylline under certain conditions exert a stimulating effect on the heart, but under these conditions exert a stimulating effect on the heart, but under these conditions they usually also produce an undesirable rise in the blood pressure.


Heats Of Solution Of Silver Halides In Liquid Ammonia, Donald K. Stevens Jun 1943

Heats Of Solution Of Silver Halides In Liquid Ammonia, Donald K. Stevens

Honors Theses

It was the hope of the experimenters to make use of one of the advantages of liquid ammonia, that of the solubility of metallic sodium to give a free electron, to find the heat of reduction of the silver ion to the metallic state.


A Study Of The Camphor Method For Molecular Weight Determinations, Harvey Douglas Boynton Jun 1943

A Study Of The Camphor Method For Molecular Weight Determinations, Harvey Douglas Boynton

Honors Theses

The determination of molecular weights accurately and quickly is of prime imporatance in analytical and organic chemistry. This problem has been attacked from many angles, the greatest success being found in cryoscopy. Man of the customary organic solvents have been used for cryoscopic determinations; they all have their advantages and limitations. These solvents in general give a very low freezing point depression. Camphor is dinstinguished from these in that it gives an unusally large freezing point depression, 40 degrees for a molal solution, and it is suited by a considerale dissolving power up to moderate concentrations.


The Reactions Of L-Chloro-L-Nitro Propane In Anhydrous Liquid Ammonia, James S. Gilmore Jun 1943

The Reactions Of L-Chloro-L-Nitro Propane In Anhydrous Liquid Ammonia, James S. Gilmore

Honors Theses

In 1939 Seigle and Hass were successful in preparing numerous dinitro paraffins such as 2, 3-dimethyl-2, 3-dinitro butane and 2, 3-dimethyl-2, 3-dinitro pentane by the reaction of salts of nitroparaffins with halonitroparaffins. They were unable to do so however, in the cases where primary nitro compounds were involved. More recently, in an unpublished work Sottysiak believed that he prepared the 2, 3-dimethyl-2, 3-dinitro butane by a Wurtz reaction in liquid ammonia, in which 2-nitro-2-chloro propane was reduced by sodium. Because of the strong reducing properties of a solution of sodium in anhydrous liquid ammonia, it was hoped that the 3, …


A Study Of The Possible Formation Of A Mixed Hydrogel Of Zirconia And Silica, Irving Goodman Jun 1943

A Study Of The Possible Formation Of A Mixed Hydrogel Of Zirconia And Silica, Irving Goodman

Honors Theses

Of course in this paper we are also interested in the gel of hydrated silica, which has been studied here thoroughly for several years. A discussion of the theory and work on this subject would take up too much time and space, since this field has been much more widely studied than any other in the field of gels. Reference to Hurd’s “Theories for the Mechanism of the Setting of Silicic Acid Gels” presents a complete summary of the theory behind the setting of this gel.

Polyhydroxyamines, John Wotiz Jan 1943

Polyhydroxyamines, John Wotiz

Master's Theses

"The industrial growth of aliphatic chemistry, which has constituted one of the outstanding advances of recent years, has been almost entirely in the field of hydrocarbons and their simpler chlorine and oxygen derivatives… Representative of the aliphatic amines, possibly only the methyl, amyl and ethanol amines may be said to have been commercially available. And yet the field of aliphatic nitrogen chemistry possesses the greatest variety of known aliphatic compounds; there are at least several nitrogen analogs of each oxygen compound, often more stable, more definitely characterized, and more reactive chemically." Relatively few aminoalcohols, especially polyhydroxyaminoalcohols have been prepared. Due …
