| Abstract | ||
| Abstract The study includes the preparation of four phenolic Schiff bases derived from the 2-acetyl pyridine as a mother compound with primary amines o , m , p-amino phenols and 4-amino naphthol . The structures of these phenolic and naphtholic Schiff bases were confirmed by physical method , namely UV visible and IR spectroscopy and melting points. The main aims of the study was the determination of values for these hydroxy Schiff bases by potentrometric titration method. This method as found simple , precise and accurate . estimated , depend on the following factors :- 1. The chemical structure of imine . 2. The ambient temperature . 3. The influence of phenolic group , whether its donating or withdrawing behavior . 4. The resonance numbers of phenoxide ion in Schiff base . * See part Ι in reference (16) . | ||
