Kinetic Modeling Of Catalytic Aerogels, Yi Cao
Kinetic Modeling Of Catalytic Aerogels, Yi Cao
Honors Theses
As pollution becomes an increasing concern globally, strict regulations have been set on vehicle pollutant emissions. The three-way catalytic converter is capable of converting toxic emissions such as carbon monoxide, unburned hydrocarbons and nitrogen oxides to less hazardous waste such as carbon dioxide, water, and nitrogen. Current catalysts employ platinum group metals, which are expensive and environmentally damaging to mine. Catalytically-active aerogels such as Co-Al, Cu-Al and V-Al aerogels have shown promise as alternatives to these metals. The work presented here adapts and extends a global kinetic model which predicts the conversion of hydrocarbons and carbon monoxide on platinum catalyst …
Reactions Of Atomic Carbon With Acid Chlorides, Daniel B. Herrick
Reactions Of Atomic Carbon With Acid Chlorides, Daniel B. Herrick
Honors Theses
This thesis is the first report of reactions of atomic carbon with acid chlorides. Carbon is known to react with phosgene to afford dichlorocarbene. We report a similar reaction with carbon and acid chlorides, generating alkylchlorocarbenes. We examine both the nature of the carbene products generated through deoxygenation and the general reactivity of carbon with the acid chlorides. We report two ways in which carbon reacts with acid chlorides. First, as expected from prior work with phosgene, carbon deoxygenates the carbonyl group yielding alkylchlorcarbenes, which rearrange as expected. Second, carbon abstracts the chlorine, and generates the acyl radical, which, in …
