The ultra-violet absorption spectra of certain ketimines and their related ketones
Degree GrantorUniversity of Canterbury
Degree NameMaster of Science
1. A review has been made if the preparation and properties of ketimines. At present no similar review exists in the chemical literature. 2. A discussion of the processes of absorption, with particular reference to the carbonyl group has been offered. The discussion includes certain effects taking place, hyperconjugation being the most relevant to the thesis. 3. A series of diaryl ketones and ketimines has been prepared and studies by ultra violet spectroscopy; four of these compounds (p-ethyl-, p-iso-propyl-, and p-tert.butyl-benzophenoneimine hydrocloroides, and p-tert.-butyl-benzophenone) have not been prepared before. The preparation and ultra violet absorption study of fencehone and fenchone-imine, have been described. 4. The Hilger Uvispek Spectrophotometer has been described and its limitations, with respect to acccuracy, discussed.
