Mass-flow control system utilizing flow-feedback for gas chromatography

Creator:: Dodo, Gerald Haruo
Abstract:: A unique mass-flow control system for the carrier gas in gas chromatography is described and evaluated. Carrier gas flow is controlled by a flow sensor, feedback electronics, a flow-control valve and a microcomputer. The flow-rate is monitored by a mass-flow meter by this system and the flow is adjusted in...

Cyclization of organolithium and -zirconium compounds ; Rearrangements of selected anionic compounds in highly disassociative solvents

Creator:: Bass, Lawrence W.
Abstract:: Intramolecular cyclization of organometallic compounds represents a promising tool for synthesis. The reaction involves exothermic consumption of intramolecular double bonds via insertion into a carbon metal sigma bond. This represents an intramolecular example of the reaction type responsible for metal catalyzed polymerization of olefins. Organolithium reagents were found to cyclize...

Steroid organoborane reactions

Creator:: Byall, Elliott Bruce
Abstract:: Steroid organoboranes have been found to be useful synthetic intermediates. Attempted pyrolyses, based on simple trialkylborane cyclizations, have not yielded C-19 or C-18 functionalized steroids, but have produced isomerized systems not otherwise available. Thus, hydroboration of cholesterol followed by pyrolysis at 215° gives 31% of 2-cholestene-6α-ol and 49% of a...

Experimental and theoretical investigation of the ability of oxygen-containing molecules to accept charge

Creator:: Siggel, Michele Ruth Fisher
Abstract:: The question of why carboxylic acids and phenols are stronger acids than alcohols has been investigated experimentally and theoretically. The experimental approach involves comparison of gas-phase acidities and core-ionization energies. The theoretical treatment uses calculated point potentials and acidities. The ease of proton removal is related to two factors known...

Steroid dialkylcarbene reactions

Creator:: Dixon, Dale David
Abstract:: Steroid carbenes have been investigated as synthetic intermediates. Basic decomposition of 4-en-3-one tosylhydrazones (and other A-ring systems) gives varying amounts of 2, 4-dienes, and solvent derived products with diglyme, heptane, tetrachloroethylene, carbon tetrachloride, benzene and cyclohexene. A method for separating complex product mixtures was developed and a study of the...

The development of a high spectral-resolution laser-excited molecular fluorescence system and its application to gas chromatography and the determination of polynuclear aromatic hydrocarbons

Creator:: Hein, Scott J.
Abstract:: A high-spectral resolution laser-excited molecular fluorescence system was developed that utilizes a pulsed supersonic expansion to simplify the fluorescence excitation spectra of large, gas-phase aromatic molecules diluted in an excess of a monatomic gas. A microcomputer was used to control and synchronize the instrumental components, which included a Chromatix CMX-4...
