    摘要: Compounds known as "solid dispersed dyes" are synthesized in a two-phase system from which they disproportionate into a water-immiscible solvent phase, providing marker solutions. Marker solution is added to a petroleum fuel to introduce the compound thereto in dissolved form. Subsequently, extraction of the compound with acidic aqueous solution produces a chromophoric reaction which indicates presence of the compound in the petroleum fuel.
