Pyridinium Derivatives of 9,10-Endo-o-Phenylene-9,10-Dihydro-1,4-Anthraquinone

Pyridinium Derivatives of 9,10-Endo-o-Phenylene-9,10-Dihydro-1,4-Anthraquinone

Date: 1956
Creator: Maglaughlin, Edward Phillip
Description: The compounds reported here were prepared for the purpose of determining the effects of active groups on the pyridine ring, and to determine the effects of substituted methyl groups on the nucleus. These compounds are to be tested for tuberculostatic activity.

A Study of the Friedel-Craft Reactions of Phenolic Ethers

A Study of the Friedel-Craft Reactions of Phenolic Ethers

Date: January 1959
Creator: Roberson, Charles Ray
Description: The original purpose of this investigation was to prepare a series of diketones. However, since considerable difficulty was encountered in the preparation of these diketones, attention was shifted to a study of the Friedel-Craft reactions of phenolic ethers and to the reaction between phenolic ethers and dicarboxylic acids with boron trifluoride as a catalyst.

The Adsorption of Radioactive Isotopes on Precipitates

The Adsorption of Radioactive Isotopes on Precipitates

Date: January 1954
Creator: Bulloch, Newman Payne
Description: This thesis concerns the investigation of radioisotopes as indicators for precipitation reactions. As a precipitate forms in the presence of a radioisotope, adsorption may take place on its surface. If this adsorption changes markedly at the stoichiometric point it will be possible to use this variation as an indicator for the reaction.

A Study of Sympathiomimetic Amines, Synthesis of O-Alkylhydroxylamines

A Study of Sympathiomimetic Amines, Synthesis of O-Alkylhydroxylamines

Date: 1947
Creator: Robbins, Margaret C.
Description: 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.
