摘要：

The ozonation of quinoline in aqueous solution has been studied at varying pH (1.8-6.5). The effects of direct and radicalic ozonation mechanisms upon process development are separately investigated by means of radical scavenger (t-BuOH 20 mM) addition to the reacting system. Direct ozonation of both quinoline and quinolinium ion leads mainly to production of quinolinic acid with a minor occurrence of cleavage reactions of the hetercyclic ring. Higher system reactivities are observed for ozonation experiments with no radical scavenger addition with small changes occurring in the distribution of products deriving from quinoline oxidation. System behaviors at varying experimental conditions are explained on the basis of chemical reaction schemes.
