The Preparation Of Certain Organic Chloroformates And Carbonates, Robert E. Brailsford Apr 1947

The Preparation Of Certain Organic Chloroformates And Carbonates, Robert E. Brailsford

Theses and Dissertations

This brief discussion and research paper attempts to correlate a large portion of the information about the preparation of known organic chloroformates and carbonates, to point out the present and possible future uses of these compounds, and to contribute some information concerning the preparation of a number of the organic carbonates. A comparison of the different methods of preparation is made.

Studies In The Determination Of Iodine In Soils Organic Materials, And Waters, Russell T. Lundell Aug 1946

Studies In The Determination Of Iodine In Soils Organic Materials, And Waters, Russell T. Lundell

Theses and Dissertations

A summary of the literature on the nutritional value of iodine in the diet of various forms of life is given. The majority of evidence indicates that iodine is an essential element in plant and animal nutrition. It functions particularly in animal metabolism in the form of thyroxine. The occurrence of iodine in a nature has been briefly discussed. Investigations made in this regard indicate iodine to be almost universally distributed in very minute amounts. Most iodine salts are soluble in water and their distribution is affected by water movements. Results of iodine determinations made during the course of this …

A Study Of Form And Content For A Laboratory Manual To Be Used By Students In General Chemistry Laboratory, Berne P. Broadbent Jan 1946

A Study Of Form And Content For A Laboratory Manual To Be Used By Students In General Chemistry Laboratory, Berne P. Broadbent

Theses and Dissertations

This investigation was carried out for general chemistry classes in which recitation and laboratory work are closely integrated and in which very close supervision is given to laboratory classes. Results indicate that there are fewer failures under these conditions if students do individual work. Students receiving grades of over 80% seem to work just as effectively in pairs as they do when working individually, but about 5% who fail when working in pairs could, apparently obtain grades above 60% if they did individual work. The formal full statement type of report is substantially more effective than the questionaire report as …

The Preparation And Properties Of Diphenylthiocarbazone, Floyd C. Mcintire Jan 1937

The Preparation And Properties Of Diphenylthiocarbazone, Floyd C. Mcintire

Theses and Dissertations

At present the chemical literature offers no method for the preparation of diphenylthiocarbazone, or dithizone, sufficiently detailed to guide the average laboratory technician in an economical and successful preparation of this compound. The high price of dithizone and the limited number of dispensers of it emphasize the need of such a method. The original research reported in this thesis was done primarily in an attempt to formulate a satisfactory detailed method for the preparation of dithizone. The suggestions of Emil Fischer were followed and an attampt was made to improve his outline and to note the possible errors so that …

An Historic Account Of Music Criticism And Music Critics In Utah, Basil Hansen May 1933

An Historic Account Of Music Criticism And Music Critics In Utah, Basil Hansen

Theses and Dissertations

My purpose in making a study of music criticism in Utah is to realize a reliable historical account of criticism as expressed by means of journals and the growth of music within the state. This study, it is granted, is not a complete history of music in Utah. It merely treats one phase of a yet unwritten history.

A secondary interest is to defend the assertion that Utah has had music criticism and not to eulogize or deride the music pioneers of the state. It may also impress the need of constructive criticism to insure the stimulus and incentive necessary …

Iron And Cobalt Salts As Catalysts In The Oxidation Of Sodium Sulfite By Free Oxygen, Loren C. Bryner Jan 1930

Iron And Cobalt Salts As Catalysts In The Oxidation Of Sodium Sulfite By Free Oxygen, Loren C. Bryner

Theses and Dissertations

The present investigation was carried out to show the catalytic effect of some iron and cobalt salts on the oxidation of sodium sulfite solutions by free oxygen. The rate of reaction was determined by measuring the volume of water required to replace the absorbed oxygen. A photograph and diagrammatical arrangement of the apparatus is given, (Page 14). From the preliminary experiments it was found that the rate of oxidation of sodium sulfite solutions is dependent upon concentration, and speed of the shaker.
