A Study of the Equilibrium Between Benzoin and Benzaldehyde in Alcohol Solutions
(Creighton University, 1936)
The reversibility of the benzoin condensation was demonstrated for the first time by Anderson and Jacobson at the University of Nebraska. They obtained benzaldehyde by reacting pure benzoin with sodium cyanide in a 95 ethyl ...
The Partial Pressure of Hydrogen Chloride from its Solutions in Non-Aqueous Solvents at 25° C. III. Ethylene Glycol Solutions
(Creighton University, 1939)
The study of the partial pressure of hydrogen chloride from solutions in various non-aqueous solvents has already been started by Schmelzle1 and Westfall. These investigators carried out their work using benzene and ...
A Method of Preparation of 4-Nitro Diphenyl Ether
(Creighton University, 1934)
Diphenyl ether was prepared as early as 1843 "by Ettling and Stonehouse. They subjected copper benzoate to destructive distillation. This was repeated by List and Limpricht (1855) and Fittig. (1862) |Maikopar (1873) first ...
An Apparatus for Measuring the Vapor Pressure of Liquids by the Gas Saturation Method
(Creighton University, 1937)
In a projected study of acid and base equilibria in non-aqueous solvents, it was found desirable to determine the vapor pressures of weak bases from these solutions, for example, solutions of ammonia in benzene and ethyl ...
Partial Pressure of Hydrogen Chloride Above its Solutions in Non-aqueous Solvents. II Nitrobenzene Solutions
(Creighton University, 1938)
It has been pointed out by Rodebush and Ewart and in the first paper of this series that the vapor pressure of a volatile acid solute like hydrogen chloride provides a measure of the basicity of the solvent. The importance ...
The Partial Pressure of Hydrogen Chloride Above its Solutions in Non-Aqueous Solvents. I. Benzene Solutions
(Creighton University, 1938)
According to the Bronsted concept of acids and bases, an acid dissociates only upon cooperation on the part of the solvent. The solvent in terms of this concept is a base, and the products of the acid-base reaction are ...
The Use of Sodium Tellurite as a Laboratory Reagent in the Detection of Sugar
(Creighton University, 1931)
Tellurium (Gr., the earth) was discovered in 1782 by Muller Von Reichenstein and was more fully investigated by Klaproth and Berzelius. It is an element of rare occurrence and is found chiefly in Transylvania, the Altai ...
Inorganic Color Standards for Colorimetric Hydrogen Ion Determinations
(Creighton University, 1932)
Aside from the wide commercial use of indicators to determine hydrogen ion concentration, there is a distinct tendency to emphasize this colorimetric method in physiological chemistry texts, and to include it as a study ...
A Study of the Solubility of Potassium Chloride in the Presence of a Strong Electrolyte With No Common Ions
(Creighton University, 1934)
When a salt is in equilibrium with its saturated solution, the activity of the solid equals the activity of the salt in the saturated solution. At constant temperature and pressure, the activity of the solid will be a constant k'.
A Modification of the General Analytical Procedure as Applied to the Detection of Arsenic
(Creighton University, 1934)
The separation and detection of the element arsenic in qualitative chemical analysis has always "been more or less of a stumbling block to the beginner in this branch of chemistry. This is due to the fact that there is at ...
