An Introduction To The Study Of Chromatography Of Aureomycin ..., Øistein Skjellum

University of the Pacific Theses and Dissertations

Part of a current research program undertaken by the faculty in chemistry at the College of the Pacific is concerned with studying chemical compounds which are favorably absorbed in Aureomycin. The reason for this preference of absorption is still not known. In order to determine the cause of this absorption, it is necessary to establish a method of recovering tetracycline and its derivatives from malignant tissue. When working with recovery of tetracycline and its derivatives, the small scale of operations immediately suggests the use of chromatographic techniques of separation, identification, and estimation.

A Kinetic Study Of The Reaction Between Acetic Anhydride And Isobutyl Alcohol Using A Chemical Oscillometer, Charles Huffman Lewis Jr.

University of the Pacific Theses and Dissertations

The object of this research project is to investigate the base catalyzed reaction of acetic anhydride and isobutyl alcohol reacting to form acetic acid and isobutyl acetate. In this investigation, a high frequency oscillometer is used to observe the progress of the reaction as it proceeds to the formation of products.

The chemical oscillometer, in one form or another, has been in existence for over twenty years. During this time it has developed from a laboratory curiosity to a practical instrument with a great number of applications. However, its use in connection with kinetic studies has not been too active …

Condensation Of Terephthalaldehyde And Hydroxyacetophenones, Ernest John Bonelli

University of the Pacific Theses and Dissertations

Organic pigments were the source of coloring matters used by man until comparatively recent times. It is to be presumed that the first steps in the use of these pigments no dyes resulted from the accidental staining of the skin or fabric by a vegetable material. Prehistoric man, in order to decorate his implements or his person, or even to make records of his mode of life, used the materials with which he came in daily contact. Coloring materials included earth and vegetable substances found in flowers, seeds, berries, nuts, bark, wood, and roots, and less readily available coloring materials …
