The Determination Of Biological Activity And Biochemical Mode Of Action For The Oxadiazole And Diacylhdrazine Insecticides, Bonnie M. Gunn
The Determination Of Biological Activity And Biochemical Mode Of Action For The Oxadiazole And Diacylhdrazine Insecticides, Bonnie M. Gunn
Retrospective Theses and Dissertations
This report includes the determination of activity and possible mode of action for a group of potential new insecticides. The biological screening procedure was developed using Drosophila melanogaster as the test organism while Musca domestica was used for mode of action assays. The percent kill for each compound is based on the number of eggs placed on media containing the insecticide minus the number of adults enclosed as compared to the control media reared flies. Observations were made on all stages from eggs through adults to determine time of death and if any malformations were present. These observations aided in …
Synergistic Effects In Bimetallic Hydrogenation Catalysts, Kathleen L. Mcintyre
Synergistic Effects In Bimetallic Hydrogenation Catalysts, Kathleen L. Mcintyre
Retrospective Theses and Dissertations
Mono and bimetallic catalysts of varying composition were prepared in order to examine any synergistic effect that may occur by mixing metals on a support. The test reactions were hydrogenation of 1, 3-butadiene and piperylene, a mixture of similar boiling 5-carbon olefins. Catalysts containing ruthenium and rhodium displayed some synergistic effects when supported on silica gel and 13X molecular sieves. The use of 5A molecular sieves as a support was used to examine the feasibility of selective hydrogenation as a separation tool for the piperylene mixture.
I. The Use Of Polyethers As Phase Transfer Catalysts For The Fluoroalkoxylation Of Halogenated Aromatic And Heteroaromatic Systems Ii. The Grignard Addition And Sodium Cyanoborohydride Reduction Of Arylchloropropeniminium Salts, Martin A.M. Moebus
Retrospective Theses and Dissertations
This research addresses two distinct areas of synthetic organic chemistry: the use of phase transfer catalysts for the fluoroalkoxylation of activated haloaromatic and haloheteroaromatic systems, as well as the Grignard addition and sodium cyanoborohydride reduction of aryl chloropropeniminium salts. In Part I of this research, a number of macrocyclic- and linear polytethers were studied as phase transfer catalysts in the nucleophilic aromatic substitution of haloaromitc systems. The most effective catalyst was determined to be poly(ethylene glycol)-8000 and the reaction conditions were optimized for this catalyst. Subsequently isomer reactivity, effects of activating groups, effects of leaving groups, and nucleophiles were studied …
Attenuation Of Infrared Radiation By Diesel Fuel Generated Particle And Droplet Aerosols, Soodabeh Karimi
Attenuation Of Infrared Radiation By Diesel Fuel Generated Particle And Droplet Aerosols, Soodabeh Karimi
Retrospective Theses and Dissertations
The object of this project was to explore the absorbance and scattering properties of carbon particle smoke in the infrared and visible regions of the spectrum. Laboratory scale apparatus were developed to produce smoke in the form of carbon particles, droplet aerosols and combinations of the two. These smokes were made from diesel fuel and fog oil.
