An Experimental Investigation Of Coloring Matter In Canna Indica Flowers, James Clinton Vogt
An Experimental Investigation Of Coloring Matter In Canna Indica Flowers, James Clinton Vogt
University of the Pacific Theses and Dissertations
The research was carried out for the purpose of isolating and identifying the coloring matter in flowers of the canna indica (canna lily) variety. It was done by extracting the pigment from flower petals with methanol, amyl alcohol, and other solvents, and crystallizing the pigment as a salt. Physical properties such as solubility, color reactions, spectra and others were examined for this pigment. Chemical properties and degradation products were also examined in order to identify the chemical structure of the pigment.
Identification Of The Products And Mechanism Of Decomposition Of Thiazate, Paul Edward Williams
Identification Of The Products And Mechanism Of Decomposition Of Thiazate, Paul Edward Williams
University of the Pacific Theses and Dissertations
This work is an additional facet of the research undertaken by Dr. Herschel Frye of the Department of Chemistry of the University of the Pacific while he was a graduate student at the University of Oregon. Frye succeeded in making an analytical reagent for zinc and other transition metals similar to dithiszone but water soluble. His approach was to to sulfonate the benzene rings thus giving water solubility because of the ionic nature of the sulfonic acid. The new reagent-tensed thiazate--was quite successful in its purpose, but the sections of the compound were somewhat different than dithizone. The purpose of …
