The ultra-violet absorption spectra of certain ketimines and their related ketones

Abstract

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