In this study, Synthesis and application of Mono(Di)-methine quinoline heterocyclic derivatives. Quinoline was reacted with ethyl(amyl) iodide to give 1-substituted-2(4)-methyl quinoline, resulted in producing a series of Mono(Di)-methine and Aza- methine quinoline heterocyclic derivatives.
In part one, quinoline was condensed with terephthalaldehyde to give a series of Di-methine quinoline derivatives, which leads to a series of violet to purplish blue coloured.
In part two, quinoline was condensed with heterocyclic compounds of keton structure to give a series of Mono(Di)-methine quinoline derivatives, which leads to a series of reddish purple to purplish blue coloured.
In part three, quinoline was condensed with nitrosoaniline derivatives to give a series of Aza-methine quinoline derivatives, which leads to a series of purplish blue to blue coloured.
In part four, quinoline was condensed with aromatic aldehyde to give a series of Mono-methine quinoline derivatives, which leads to a series of purplish red to purplish blue coloured.
The identification of the structure of the those heterocyclic compounds were confirmed by IR, Mass, UV, H-NMR, EA spectra analysis. These quinoline dyes are suitable for dyeing of PAN fabrics, to proceed tested and appraised of the hues to use (A.C.S.), ranging from reddish purple to blue.
