An approach to synthesis of trichodiene
(1978)
The purpose of this study was to develop a novel synthetic method to synthesize trichodiene (1). This study has utilized 2-methyl- Δ¹- cyclopentenecarboxylic acid (23) as the starting material for the preparation of dienone ...
An infrared spectroscopic study of surface reactions on lanthanum sesquioxide and a 1:1 mixture of lanthanum oxychloride and lanthanum sesquioxide
(1977)
Infrared spectroscopy was used to examine the surface properties of catalytic La₂Og₃ and a 1:1 mixture of LaOCl + La₂Og₃. Spectral studies of the dehydration/rehydration of the La(OH)₃/La₂O₃ system revealed the existence ...
Pulsed laser excited fluorescence of fluoranthene
(1975)
A pulsed laser spectroscopy system has been designed, constructed, and applied to the study of the dual fluorescence of fluoranthene. The apparatus incorporates a pulsed molecular nitrogen gas laser, or nitrogen laser ...
The characterization and potential utilization of the phenolic compounds found in a pyrolytic oil
(1979)
The liquid fraction from the pyrolysis of wood waste material was studied for qualitative and quantitative phenolic content by gas chromatography and mass spectrometry. The total phenolic content detected by chromatography ...
Rhenium and technetium porphyrin complexes with unusual geometries
(1975)
Monometallic and bimetallic porphyrin complexes of rhenium and technetium nave been synthesized by reaction of stoichiometric quantities of Re₂(CO)�₀ or Tc₂(CO)�₀ with porphyrin In refluxing decalin under argon. ...
ESR studies of hindered phenoxy radicals
(1970)
Oxidation of 2,6-di-tert.-buty1-4-methyl phenol, 2,6-di-tert.- buty1-4-ethyl phenol and 2,6-di-tert.-buty1-4-n-propy1 phenol with lead dioxide or iodine produces the corresponding 2,6-di-tert.- buty1-4-alkyl phenoxy radicals. ...
Electron spin resonance studies of steric and solvent interactions in organic radical anions
(1970)
Steric effects of nitroaromatic radical anions have been studied utilizing esr spectroscopy. We have chosen to study the sym-trialkylnitrobenzene radical anions in solvents which offer additional steric requirements such ...
Kinetic study of free radicals in the titanium (III) - hydrogen peroxide - alcohol reaction system
(1970)
Detailed kinetic studies on Ti(III)--H₂O₂--alcohol reaction systems have supplied evidence for decay reactions of hydroxy alkyl radicals (·R-OH) derived from methanol, ethanol, 2-propanol, and t-butanol. As determined ...
A study of the transfer processes of phthalate esters to the marine environment
(1975)
In recent years, environmental scientists have been concerned with the release of phthalate plasticizers into the environment (1). To determine their distribution, rates of input and accumulation, and to identify their ...
