Nmr Characterization Of Parathion: Properties, Transport, And Reaction Kinetics, Emma Catherine Baker

Boise State University Theses and Dissertations

The hydrolysis reaction of parathion (PTH) to produce para-nitrophenolate (pNP) and O,O-diethylthiophosphate (DETP) was examined in a minimally disturbed liquid-liquid biphasic reaction system by proton and phosphorous nuclear magnetic resonance spectroscopy. The effect of the micellar cationic surfactant, cetyltrimethylammonium chloride (CTAC), on PTH transport, hydrolysis, and system characteristics including reactant-product concentrations, pNP partition coefficients, pNP surface activity, ultraviolet degradation of pNP, oxidation of pNP, and impurities in PTH are reported. Surfactant reaction systems resulted in a 2.5 order of magnitude increase in the amount of PTH transported into the aqueous layer as compared to the control system at 2100 …

The Kinetics And Mechanisms Of Some Fundamental Organic Reactions Of Nitro Compounds, Zhao Li

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In chemistry, kinetics is the study of the rates of chemical reactions. A reaction mechanism describes in detail exactly what takes place at each stage of an overall chemical reaction from reactants to products. The work outlined in this dissertation was carried out in order to find out the true mechanisms of some fundamental organic reactions of nitro compounds by means of a series of novel kinetic techniques and analysis methods.

The target reactions include (1) the proton transfer reactions of nitroalkanes and (2) the aromatic nucleophilic reactions of trinitroarenes, both of which are undeniably among the most elementary and …
