Determination Of Thallium(Iii) Using The Dead-Stop End Point, Richard Blount Williams

University of the Pacific Theses and Dissertations

An accurate and fairly rapid method of analysis of thallium solutions is desirable in order to facilitate further investigation of the chemistry of thallium. The dead-stop titration method which has been successfully applied to other metals of Group 3b, will not be applied to the quantitative determination of the thallium (III) ion in aqueous solution.

Hydrolysis Of Alpha-D-Glucosamine-L-Phosphate, Michael James Pizanis

University of the Pacific Theses and Dissertations

Some information on the hydrolysis mechanism of phosphate esters was obtained by studying the kinetics of ∝-D-Glucosamine-1-phosphate.

∝-D-Glucosamine-1-phosphate was synthesized, an experimental pH-rate profile for the hydrolysis of this phosphate was determined at 100 C.

It was proposed that Species I (see page 7) had P-O cleavage with intramolecular proton transfer to ester oxygen. Species II is believed to have the same mechanism of hydrolysis as monoanion of methyl phosphate and monoanion of ∝-D-Glucosamine-1-phosphate. This study indicates that Species III s reactive, while the dianion of methyl phosphate and the dianion of ∝-D-Glucosamine-1-phosphate are inactive. The increased reactivity of Species …

Rates Of Acidic Hydrolysis Of Triptych Boroxazolidines, Ronald Keith Stump

University of the Pacific Theses and Dissertations

Upon looking at the results of calculation of the rate constants given in Table 2, there are revealed some general trends as to the influence of the substituent groups on the values of the rate constants. If the rate constants of the reaction are considered at a fixed temperature, the rates of reaction in Group I decrease as the substituent is gradually changed from methyl to isopropyl. As soon as the substituent is changed from alkyl to an ether type,the rate of cleavage increases nearer to that of the parent compound again. The rate of cleavage of the nitrogen-boron bond …

A Paleontological Study Of The Gunflint Microfossil Assemblage, J. William Schopf

Honors Papers

Precambrian microfossils discovered in nonferruginous charts of the lower "algal" members of the Gunflint formation of southern Ontario are of great interest in the evolutionary scheme of primitive life. The environment of deposition of the deposit, and the indigenous and biogenic nature of the microfossil assemblage are considered. A discussion of the small but diversified assemblage, including twelve micro-forms, seven of which have not previously been reported, is presented.

Pollution-Caused Fish Kills In 1962

Other Publications in Wildlife Management

This publication is the third annual report of fish kills caused by pollution occurring in the United States. The reporting of pollution-caused fish kills was begun by the Public Health Service in the Spring of 1960 in an effort to secure additional information on the effects of pollution in the Nation's waters, to elicit the cooperation and assistance of conservation groups in the States to help determine causes of fish kills and assist in their abatement, and to place responsibility for fish kills where it belonged.

The Surgeon General asked all State conservation and fish and game agencies to assist …

An Investigation Of Drift-Covered Environments Using The Shallow Reflection Seismic Method, Kalamazoo County, Michigan, Thomas Patrick Luby

Masters Theses

Seismic work utilizing a six-channel analog seismograph and a hammer impact source successfully obtained coherent reflection events from horizon within the glacial overburden, from the drift-paleozoic interface, and from Paleozoic bedrock targets. Fieldwork was conducted in eight drift-covered environments where the drift thickness varied from 80 feet to greater than 500 feet. Factors that exerted a major control over the seismic response at each environment studied include the depth of the water table, the type of surface material underlying the shot point and geophone spread, and the use of single versus multiple geophones per channel. Each of these factors influenced …

Survey Of Job Satisfaction Among Ancillary Personnel, Helen Brown Austin

Loma Linda University Electronic Theses, Dissertations & Projects

On the assumption that there is less turnover and optimum performance among employees who receive a high level of Job satisfaction, this study was undertaken to obtain data that administration could use in evaluating Job satisfaction among ancillary personnel.

The normative-survey was the method chosen and a standardized tool, the S.R.A, Employee Inventory, developed by the Science Research Associates of the University of Chicago, was employed for collecting the data. Ninety-five per cent of the ancillary staff, in the selected hospital, participated in the study. After tallying the responses to the questionnaire items, the results were sent to the Science …

Development Of Water Quality Criteria For Aquatic Life, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

It is now recognized that water pollution is an important problem, that it becomes more widespread and serious as population and industry expand, and that something must be done if aquatic life resource are to be saved and their productivity maintained. In the past there has been a great deal of uncertainty in approaching this situation and a general lack of understanding of the details and ramification of the overall problem. In the efforts for the abatement of pollution, only a few clearcut objectives have been established. Knowledge is lacking as to what the objectives should be. There is still …

Kinetic Investigation Of The Hydrochlorination Of Olefins In Aprotic Solvents And Sulfonation Of Idobenzene And The Selectivity Relation, Thomas Glen Davies

Theses and Dissertations

Kinetic investigation of the hydrochlorination of cyclohexene and cis-2-butene in n-heptane with SnCl4 as catalyst shows that the reaction is second order with respect to both olefin and catalyst. The specific rate constants at 25° , 0° and -23.8°C and the activation parameters were determined. Investigation of the Ga2Cl6 catalyzed hydrochlorination of cyclohexene and cis-2-butene in dichloromethane indicates that alkylation and polymerization compete with the hydrochlorination reaction in the presence of the solvent. The relative reaction rates and the isomer distribution for the sulfonation of iodobenzene by S35O3 have been determined in refluxing SO2 at -10°C. The reaction resulted in …

Sulfonation Of Chlorobenzene And The Selectivity Relation ; Bromine Addition To Cyclohexene In Dichloromethane ; Thorpe's Synthesis Of The Caged Acid, 4-Methyltricyclo[1.1.0.0[Superscript 2-4]] Butane-1,2,3-Tricarboxylic Acid, John A. Gurney

Theses and Dissertations

Aromatic sulfonation and some substitution reactions of chlorobenzene show deviations in the selectivity relation. A determination of chlorobenzene sulfonation provided the following rate ratio relative to benzene and partial rate factors: 1.0, [---] of 0.064 , mf 1.7 and pf 4. 2. Our work, Olah's nitration, Ferguson's bromination and Stock's chlorination define a new relation that can be express by adding an entropy term (A) to the selectivity relation. We determined the rate of bromine-cyclohexene addition in dichloro-methane at 0° to provide a basis for a systematic variation of solvents at low temperature. An unusual zero-order reaction was encountered. The …

Dissertation In Organic Chemistry. Part I, The Fate Of The Anilino Moiety In The Rearrangement Of Α-Anilonoketones. Part Ii, Partial Rate Factors For Sulfonation Of Bromebenzene With Sulfur Trioxide. Part Iii., Preliminary Survey On The Effect Of High Pressure On Ferrocene And Cycloöctatetraene, Jerold Carter Robertson

Theses and Dissertations

Part I. The rearrangement of α-anilinoketones was studied in an effort to determine the mode of movement of the nitrogen moiety. A crossover experiment was carried out with an equimolar mixture of 2-(4- bromoanilino)-1-(4-bromophenyl)-2-(4-methoxyphenyl) ethanone and 2-(4-chloroanilino)-1-(4-chlorophenyl) -2-(4-methoxyphenyl)ethanone with γ- picoline hydrobromide as the catalyst. The reaction product was analysed by means of a mass spectrograph. The results of the analysis indicate a crossover of the nitrogen moiety during rearrangement. This indicates that the nitrogen moiety moves in an intermolecular manner during the rearrangement. Part II. The isomer distribution from the sulfonation of bromobenzene with sulfur trioxide was determined by …

The Correlation Of Spectra And Steric Effects In Alkyl And Aryl Hydrazones, Dennis J. Weber

Masters Theses

Introduction

The correlation of spectra, especially ultraviolet spectra, of hydrazones with their structure has resulted in considerable confusion because of the variations in spectra obtained from apparently the same basic chromophore.
