Triggering materials responsible for coloring of coal liquids have been searched by comparing the structures of the colored materials derived from the neutrals, acids, and bases of the coal liquid and the nitrogenous model compounds. Basic constituents of the coal liquid are most prone to photooxidation and afford colored materials of higher molecular weight and stronger absorption in the visible region. Model compound studies suggest that they are predominantly formed in the photoinduced oxidative coupling of aromatic amines.
