(University of St Andrews, 1964) - ThesisThe application of various chromatographic technique to the mixed esters prepared from shellac has led to the discovery of ether-linked polymer fragments in shellac and the isolation and identification of a number of ... -
Macrocyclic complexes and their use as electrocatalysts for the electrochemical reducation of carbon dioxide
(University of St Andrews, 1995) - ThesisThe environmental problem of carbon dioxide pollution has caused considerable interest over recent years. Much work has concentrated on catalysts for the reduction of carbon dioxide. There are two main methods for the ... -
The pyrolysis of triphenyimethane, carbazole and toluene
(University of St Andrews, 1956) - ThesisIn all the studies reported in the subsequent sections a common method of approach has been followed. As a preliminary to the kinetic work, detailed investigations have been made of the precise nature and stoichiometry of ... -
The phosphorylation of some analogues of fructose by yeast hexokinase
(University of St Andrews, 1959) - ThesisSince Meyerhof separated hexokinase in a purified form from bakers’ yeast a great deal of information on the properties of this enzyme has bene obtained by numerous workers. In particular the question of the specificity ... -
Studies of 1, 6, 6a-trithiapentalenes and related systems, with special reference to nitrogen analogues
(University of St Andrews, 1974) - ThesisAn attempted synthesis of 1,6-dimethyl-6a-thia-1,6-diaza-pentalene from 2,5-dimethylisothiazolium perchlorate was unsuccessful. In the course of the work it was found that 2,5-dimethylisothiazolium perchlorate reacts with ...
