An Electrochemical Determination Of The Thermodynamic Properties Of Silver And Mercury Sulfides, Arthur G. Cole
An Electrochemical Determination Of The Thermodynamic Properties Of Silver And Mercury Sulfides, Arthur G. Cole
Theses and Dissertations
The problem consists of measuring accurately the free energy of formation, heat of formation, entropy, and solubility product constant of silver and mercury sulfides, and is a part of a larger study extending to many other metal sulfides. The confusion now existing in the chemical literature amply justifies a study of this nature. The thermodynamic properties of several important metal sulfides have never been measured, and the only values available for them are estimates. Determinations of the properties of many other metal sulfides have been carried out, but the results given by different authors often differ widely.
Factors Influencing The Solubility And Oxidation Of Commercial Iron Pyrites, Neldon Lamont Jensen
Factors Influencing The Solubility And Oxidation Of Commercial Iron Pyrites, Neldon Lamont Jensen
Theses and Dissertations
Studies were made (1) to determine the effect of air and oxygen and verying concentrations in distilled water, on the solubility of iron pyrites; (2) to determine the effect of acid, base and buffer solutions of varying pH; (3) to observe the effect of some oxidizing and reducing agents on the solubility of iron pyrites. These investigations would aid in deciding the possibilities of using iron pyrites as a soil conditioner.
The Chromatographic Separation Of Gilsonite, Harold Albert Bezzant
The Chromatographic Separation Of Gilsonite, Harold Albert Bezzant
Theses and Dissertations
Separation of natural hydrocarbon minerals into their constituents non-destructively is a very difficult problem. A non-destructive analysis of the hydrocarbon minerals is essential to their wise utilization. Chromatography represents a non-destructive means of separating adsorbable substances non-destructively with a high degree of purity. The chromatographic separation is based upon the simple principle of the difference in adsorption affinity of compounds for a particular adsorbent. The chromatographic separation of gilsonite was, therefore, undertaken in an effort to prove that the adsorbable compounds of this hydrocarbon mineral could be separated by this simple non-destructive method. The first chromatographic columns of alumina, silica …
The Preparation Of M-Ethylphenol And M-Phenylphenol From Resorcinol, Ronald Kenith Robins
The Preparation Of M-Ethylphenol And M-Phenylphenol From Resorcinol, Ronald Kenith Robins
Theses and Dissertations
The lack of a convenient method for the synthesis of m-alkylphenols has long been recognized by organic chemists. Within recent years the study of the physiological properties of these compounds and their derivatives, particularly the curare analogues, has caused much more concern to be placed upon a satisfactory method of synthesis. The problem of their synthesis offered an interesting study in synthetic organic chemistry. Both groupd, the alkyl group and the hydroxyl group of a meta-alkylated phenol, direct to the ortho and para positions. This makes it impossible to prepare the m-alkylphenols by the usual procedures employed in the synthesis …
Studies Of Some Reactions Of Quinoxaline, 2-Methyl-, And 2,3-Dimethylquinoxaline, Delos Edward Bown
Studies Of Some Reactions Of Quinoxaline, 2-Methyl-, And 2,3-Dimethylquinoxaline, Delos Edward Bown
Theses and Dissertations
Although many compounds have been prepared which contain the heterocyclic nucleus known as the quinoxaline nucleus, very little fundamental experimentation has been reported by way of expanding the chemistry of quinoxaline beyond the basic condensation reaction and its valuable use as a means of characterization, for example, the reaction of vicinal diketones with o-phenylenediamine. Also, no know effort has been made to assemble the chemistry of the quinoxalines into one paper for ready reference. Additional interest is concerned with the chemotherapeutic value of basically substituted quinoxalines^1; however, this aspect of the problem will not be discussed. The chemistry of quinoxaline …
