Abstract
Researchers investigate color changes of a representative FCC gasoline. They concentrated and separated the red substance in the FCC gasoline by chromatography.  They then analyzed it by elemental analysis and gas chromatography-mass spectrometry (GC-MS). They determined the main components of the red substance to be aromatic amines.
Complexes formed from quinones and aromatic amines are the reason why gasoline being red, and acids can destroy the complex by reaction with aromatic amines leading to decoloration of red gasoline. Authors propose a mechanism for the color change of gasoline.
