Siloxy-cope rearrangements of the trans-l-vinylcyclotridec-3-en-l-ol system

Creator:: Bolesta, Richard Edward
Abstract:: The thermolysis of trans-1 -trimethylsiloxy- 1-vinylcyclotridec- 3-ene (VI-OTMS) led to the formation of two major products: 4-vinylcyclotridecanone (VII) and cyclopentadec-5-en-l-one (VIII) after hydrolysis. Ketone VII is produced by a concerted [3, 3] sigmatropic shift, while ketone VIII is formed by a [1, 3] sigmatropic shift with a concerted or diradical...

Use of a tungsten filament atomizer in atomic absorption spectrometry

Creator:: Reid, Richard Donald
Abstract:: A nonflame method for atomic absorption spectroscopy is described. A helical tungsten filament from a commercially available 6-V, 4-A light bulb, heated to :incandescence in an argon atmosphere is used to atomize 2-μl aqueous samples for metals analyses. Studies of two hollow cathode lamp tungsten filament orientations, a modulated light...

A three-phase argon plasma arc for analytical emission spectroscopy

Creator:: Mattoon, Terence Richard
Abstract:: A new three-phase argon plasma arc was developed for analytical emission spectroscopy. The power supplied to the plasma arc utilized a simple circuit with three-phase as line voltage stepped down via a transformer to 104Vrms. A three concentric quartz tubing assembly was determined to be the optimum configuration for supplying...

Evaluation of a photon-counting technique for the reaction rate determination of glucose

Creator:: Rhodes, Roxie Roberta
Abstract:: A photon-counting technique which provides direct digital read-out of data has been developed and evaluated for the reaction rate determination of glucose. The enzyme catalyzed oxidation of glucose to gluconic acid and hydrogen peroxide with the subsequent reaction of hydrogen peroxide with excess iodide to produce tri-iodide is followed by...

The design of an easily operated dc argon plasma arc for atomic spectroscopic analysis

Creator:: Murdick, Dewey A.
Abstract:: A long path dc plasma arc operated in an atmosphere of argon is described. The arc is easily ignited and operated, and is inexpensive to use. Samples were introduced into the arc as solution aerosols. Radially resolved emission measurements are reported for calcium, copper, and hafnium. The detection limit for...

A study of photon counting employing a double-beam digital photometer

Creator:: Ash, Kenneth Carl
Abstract:: A double-beam photometer was designed and built employing photon counting to give a direct digital readout. It was evaluated as an analytical instrument with special emphasis on pulse recovery time, pulse interaction and instrument settings. An equation is developed to explain pulse interaction in event counting systems.

Investigation of the relationships between laser energy and vaporized target material, continuum intensity, and plume energy in laser plume spectroscopy

Creator:: Flugstad, Paul Morris
Abstract:: A focused Q-switched neodymium-doped glass laser with power levels ranging from 1-6 MW and with a 50-nsec halfwidth, was used to vaporize copper metal. Experimental measurements showed that the amount of material vaporized away from the target was not linear with laser power and was much less than could be...

An atmospheric pressure glow discharge detector for capillary column gas chromatography

Creator:: Baur, Susanna S.
Abstract:: The change in the oscillation frequency in the current of an atmospheric helium glow discharge is a sensitive detector for gas chromatography. The response of the detector is in the femtomole and picomole range for nonane and decane. The effluent of a capillary column is directed into a glow discharge...

The siloxy-cope rearrangement of 1,2-divinyl-1-trimethyl-siloxycyclohexane and related systems. The acid-catalyzed rearrangement of bicyclo [5.1.0] octyl-8-methanol

Creator:: Walton, Edward Samuel
Abstract:: Part I The pyrolysis of cis- and trans- 1, 2-divinyl-1- trimethylsiloxy - cyclohexane, II- and III-TMS, under the same conditions as the pyrolysis of cis-l-vinyl -1-trimethylsiloxycyclooct-3-ene, I-TMS, confirms that a sequence of concerted reactions for the rearrangement of II- and III-TMS to trans-l-trimethylsiloxycyclodec-3-ene, IV-TMS, is a viable pathway in the...

Preparation and comparative solubility of poly-L-tyrosyl lysozyme and poly-O-methyl-L-tyrosyl lysozyme

Creator:: Venier, Lynn Corrine
Abstract:: In order to examine some possible tyrosyl interactions, poly-tyrosyl lysozyme and poly-O-methyltyrosyl lysozyme were prepared and their solubilities were compared. Both derivatives exhibited similar pH dependent solubilities, showing a minimum solubility at about pH 8. Their solubilities varied with temperature, having a positive enthalpy of solution. The effect of a...
