Capillary Zone Electrophoresis Studies Of Sulfur Containing Compounds, Francisco Rodriguez
Capillary Zone Electrophoresis Studies Of Sulfur Containing Compounds, Francisco Rodriguez
Masters Theses & Specialist Projects
Up to this point in time, complex mixtures of tertiary sulfonium ions have been separated or analyzed employing conventional methods like HPLC or NMR procedures. In this thesis the researcher presents a new approach, the use of Capillary Zone Electrophoresis (CZE) for the analysis of these types of ions as well as the closely related thiophenium ions. CZE offers an unprecedented advantage in that separations can be employed for speciation or quantitation of complex mixtures by using the appropriate standards or specific detectors. For the study, model sulfonium and thiophenium ions were used to determine the feasibility of the separation …
A Study Of High Temperature Corrosion In An Afbc System, Wie Xie
A Study Of High Temperature Corrosion In An Afbc System, Wie Xie
Masters Theses & Specialist Projects
The occurrence of furnace wall and superheater corrosion in fluidized bed combustor systems has caused some operational and economic concerns. It is generally accepted that chlorine and sulfur may play roles in this corrosion. In order to predict the performance of high chlorine or high sulfur coals in these combustion systems, it is necessary to have a better understanding of the different corrosion mechanisms in which chlorine and sulfur may be involved. It is also important to evaluate the critical point of coal chlorine content which may cause initial corrosion. The laboratory-sized atmospheric bed combustor (AFBC) at Western Kentucky University …
Capillary Electrophoretic Separation Of Sulfoxides, Clair Davies
Capillary Electrophoretic Separation Of Sulfoxides, Clair Davies
Masters Theses & Specialist Projects
Chiral sulfoxides are most widely used in asymmetric synthesis. Their application as chiral synthons has now become a well-established and reliable strategy, mainly due to availability and high asymmetric induction exerted by the chiral sulfinyl group. Very few articles have been published on the separation of chiral sulfoxides; most involve HPLC or GC. The first separation of optically active sulfoxides was described by Phillips and co-workers. To date no work has been reported using capillary electrophoresis for the separation of alkylaryl sulfoxides. A series of alkylaryl sulfoxides were synthesized. Conditions for their separation were investigated using a modified 125 mM …
The Effects Of So2 On The Formation Of Cl2 During Co-Firing Muncipal Solid Waste With Coal, Ying Xie
The Effects Of So2 On The Formation Of Cl2 During Co-Firing Muncipal Solid Waste With Coal, Ying Xie
Masters Theses & Specialist Projects
The Deacon Reaction was proposed as a mechanism for the formation of molecular chlorine during the combustion of municipal solid waste (MSW): 4HCl + O2 ↔ 2Cl2 + 2H2O As suggested by some researchers, co-firing high sulfur coal with MSW may reduce the emission of toxic chlorinated organics, resulting from the reaction between S02 and Cl2: SO2 + Cl2 + H2O → SO3 + 2HCl The effect of sulfur dioxide on the formation of chlorine through the Deacon Reaction is investigated in this study. A Lindberg Furnace was utilized and preheated to 800°C to simulate the conditions in the AFBC …
