Heats Of Solution In Liquid Ammonia, Dorsey O. Thomas Jr.
Heats Of Solution In Liquid Ammonia, Dorsey O. Thomas Jr.
Honors Theses
The present work consists of measurements of the heats of solution of guanadine hydrocholride in this solvent. Also there will be presented a detailed description of the method of operation of the calorimeter which is being used.
Methylation Of Phenols, John James Adamzevich
Methylation Of Phenols, John James Adamzevich
Honors Theses
Although a good deal of work has been done lately on the methylation of phenols this is still a comparatively unknown field. The purpose of this investigation was to study the effect of temperature on the amount and type of product formed.
Solubility Determinations In Anhydrous Ethylenediamine, Joseph Hooker Dusenbury
Solubility Determinations In Anhydrous Ethylenediamine, Joseph Hooker Dusenbury
Honors Theses
Although the preparation of ethylenediamine is reported in the literature as early as 1853, the first isolation of the pure anhydrous compound was performed by A. W. Hoffmann in 1858. He prepared the pure diamine by repeated distillations from metallic sodium, and reported on the great stability of the 111ono-hydrate as a hindrance to obtaining the compound in a pure state, More recently, in 1934, Bailar at the University of Illinois reacted the crude diamine with zinc oxalate to give a salt which is stable at room temperature and may be heated to 200° in vacuo (all temperatures in degrees …
Dialysis Of Silicic Acid Gels, Arthur C. Glamm
Dialysis Of Silicic Acid Gels, Arthur C. Glamm
Honors Theses
The primary purpose of this investigation was to prove or disprove the existence of an equilibrium between polysilicic acid molecules and simple silicic acid molecules in a set silicic acid gel. The investigation involved the controlled dialysis of typical gels from their time mixing, through the time of set and into the aging period. Since numerous silica determinations were to be made, it was thought advisable to disregard the time consuming gravimetric method. The secondary purpose of this investigation was therefore, to determine if the colorimetric method for the determination of silica, as devised by Winkler (1) in 1914 and …
The Preparation Of Phenyldibromnitromethane, Edwin L. Mincher
The Preparation Of Phenyldibromnitromethane, Edwin L. Mincher
Honors Theses
The purpose of this research was to prepare plenyldibromnitromethane. Also it was desired to make some physical measurements on the compound if the compound could be made in sufficient quantity. So far as the author can find out, phenyldibromnitromethane is not described in the literature.
A Study Of The Action Of Potassium Hypobromite And Sodium Hypochlorite On Adipamide, William Marzluff
A Study Of The Action Of Potassium Hypobromite And Sodium Hypochlorite On Adipamide, William Marzluff
Honors Theses
The Hoffman reaction of an amide with a hypohalite to give a primary amine in excellent yields is the basis of many syntheses in organic chemistry. This project is concerned with the study of the action of sodium hypobromite and sodium hypochloride on adipamide. Isolation of reaction products, if possible, identification of reaction products, if possible, identification of the products, and determination of the yield of the reaction were desired. It was hope that a diamine, putresecine, would result from this reaction, and therefore the steps in isolation of the products were carried out with this in view.
A Partial Study Of The Reaction Between Pentanedione-2,4 And Formaldehyde, Joseph Anthony Sincius
A Partial Study Of The Reaction Between Pentanedione-2,4 And Formaldehyde, Joseph Anthony Sincius
Honors Theses
It was the purpose of this research to observe the reaction of pentanedione-2,4 with formaldehyde, and to study the principle reaction product. The secondary purpose of the research was, if possible, to obtain a cyclic compound like 1,3 dihydrorescrcinol.
