Description générale

Quinaldine is an organic compound prepared by the Skraup method from crotonaldehyde and aniline with sulfuric acid in the presence of a dehydrogenating agent. Several dyes, including trimethinecyanine dye, pinacyanol dye, vinylogous dye, quinophthalone dye and the quinaldine red are synthesized using quinaldine. Additionally, it is employed in the production of pharmaceuticals, pH indicators, food colorants, oil-soluble dyes, and other chemical compounds.

Application

Quinaldine can be used:
  • In the preparation of squaraine dyes (quinaldine-based squaraine dyes) which is biologically significant and can be used as an metal ion sensor.
  • To prepare the pH sensitive colorimetric chemo sensors.

The anaerobic degradation of quinoline, isoquinoline and 2-methylquinoline was investigated under nitrate-reducing conditions with acclimated activated sludge. Quinoline was completely transformed during degradation with an optimum COD/NO(3)-N ratio of 7. Isoquinoline and 2-methylquinoline were also completely transformed; however, nitrate consumption
