Abstract
:
The synthesis of some novel heterocyclic azo disperses dyes derived from 3, 4, 5- Subistituted 2-aminothiophne (1-11) and Julilidene will be investigated. First, the azo compounents (12-22) will be prepared using Gewald reaction starting from ketones and the aproperait active methylen compound. Then the diazonium salt formed will be coupled to Julilidene to form the desired dyes. The colour of the dyes is expected to vary from one derivative to another depending on the substitution. The coloring performance of these molecules as disperse dyes for some polymers such as poly propylene, polystyrene, etc. will be assessed. The spectral properties of these dyes will be measured for both solutions and polymeric films.
