A Study Of The Electrolytic Oxidation Of Antioxidants At A Stationary Platinum Microelectrode, Mark Anthony Forte
A Study Of The Electrolytic Oxidation Of Antioxidants At A Stationary Platinum Microelectrode, Mark Anthony Forte
Master's Theses
Phenolic antioxidants have a Wide variety of uses. They are em- ployed to prevent oxidative and thermal degradation of everything from plastics to foodstuffs. They may even have potential as carcinostatic agents. In general, they act as chain terminators in free radical type reactions.
An Atomic Absorption Method For Determining Micromolar Quantities Of Primary Aliphatic Amines In The Presence Of Secondary And Tertiary Aliphatic Amines, Nathalie Harwood Perkins
An Atomic Absorption Method For Determining Micromolar Quantities Of Primary Aliphatic Amines In The Presence Of Secondary And Tertiary Aliphatic Amines, Nathalie Harwood Perkins
Master's Theses
A method for the determination of primary aliphatic amines in the presence of secondary and tertiary amines is described. The primary amine is reacted wit ha complexing reagent containing cupric chloride, salicylaldehyde and triethanolamine. The copper complex formed is extracted into 10% hexanol in toluene. The amount of copper in the toluene layer is determined by atomic absorption spectroscopy. This is a measure of the primary amine in the sample. The method can be successfulyl applied to both monoamines and diamines as well as an amino alcohol. Data for the analysis is + 0.05% at the 2% level and below. …

Photochemical Behavior Of Some Nitrogen Heterocyclics, James Wesley Harris
Master's Theses
The compounds, 3,6-dimethoxypyridazine, l,2-dimethyl- 3,6(1H,2H)-pyridazinedione, and 6-methoxy-2-methyl-3(2H) pyridazinone, were prepared by using reported preparations. Their photochemistry was investigated and compared to the thermal chemistry and photochemistry of maleic hydrazide.
