Thermodynamics And Molecular Orbital Calculations For The Parabens, Kenneth S. Alexander Jan 1972

Thermodynamics And Molecular Orbital Calculations For The Parabens, Kenneth S. Alexander

Open Access Dissertations

The intent of this study was to follow two approaches of scientific methodology in the investigation of a chemically related series of pharmaceutical preservatives, the parabens (esters of para-hydroxybenzoic acid). One approach involved the experimental determination of the solubilities of these compounds and also included their partition coefficient determination. The other approach, strictly theoretical in nature, was manifest by the utilization of molecular orbital theory in the determination of molecular parameters and their possible correlation with physico-chemical parameters and/or drug action.

The solubilities of a series of solutes related to each other by their increasing size in alkyl chain in …

The Concentration And Distribution Of Particulate Iron In Waters Of The Northwestern Atlantic Ocean And Caribbean Sea, Peter Robin Betzer Jan 1971

The Concentration And Distribution Of Particulate Iron In Waters Of The Northwestern Atlantic Ocean And Caribbean Sea, Peter Robin Betzer

Open Access Dissertations

Measurements of particulate iron concentrations have been carried out on samples from the northwestern Atlantic Ocean, Caribbean Sea and Gulf of Mexico. Water samples were collected in 30-1 Niskin bottles; iron analyses were done by atomic absorption spectroscopy. The average of 319 iron determinations on shallow open-ocean water (0-300 m) was 0.142 ± .146 μg/1; the average of 165 determinations on samples deeper than 500 m and shallower than 1000 m from the bottom was 0.137 ± .091 μg/1. These averages are lower than previous estimates by an order of magnitude or more. Spectrophotometric and atomic-absorption analyses carried out on …


Benthic Lipids Of Narragansett Bay Fatty Acids And Hydrocarbons, John William Farrington Jan 1971

Benthic Lipids Of Narragansett Bay Fatty Acids And Hydrocarbons, John William Farrington

Open Access Dissertations

The intent of this investigation was to expand our knowledge of the biogeochemistry of fatty acids and hydrocarbons in recent sediments. Several techniques for extracting fatty acids from sediments were evaluated and saponification was found to give the best yield. Samples of sediments, sewage effluents, and benthic animals were extracted to obtain the lipid fraction. The lipid extracts were analyzed for fatty acids and hydrocarbons by gas chromatography. Lipolytic activity in the sediments was demonstrated using tributyrin and olive soil assays.

Results confirmed that consistent sampling and extraction techniques should be applied when comparing fatty acid distributions in sediments from …
