chlorophenyl radical. In the chloroform case, 15 chloroaromatics could be analysed in between C6H5Cl and C14H9Cl. The weak C-Cl bond in chloroform is responsible for the high extent of chloroaromatics formation, either by Cl abstraction from the additive or by chlorination reactions via Cl radicals. Additionally, specific pathways to (di)chloroaromatics and chlorinated fulvene-type structures are outlined
通过缩合/自由基清除方法(Hausmann,M.,Homann,K.)分析了预混合的含氯,富含燃料的低压苯/氧气火焰中(氧化的)氯芳族化合物及其自由基的形成。 -H。,1995.Ber.Busenges.Phys.Chem.99,853-862)。几种氯化有机化合物(甲基氯,叔丁基氯,氯苯,氯仿)被用作添加剂,最大浓度为总燃料的10%。通过GC / MS进行产物鉴定和定量。在以氯苯和氯仿为添加剂的情况下,这些火焰中氯代芳香族化合物的形成程度最大。对于氯苯,可以在C7H7Cl和C12H9Cl之间分析12种不同的氯代芳烃。它们的形成主要是由于最初的氯苯转化为取代或氧化的衍生物或生长产物。已证明,在含氯苯的火焰中,芳烃的额外氯化作用次要。可以鉴定出三种异构体(o / m / p)清除氯苯基的产物。在氯仿情况下,可以在C6H5Cl和C14H9Cl之间分析15种氯代芳烃。氯仿中弱的C-Cl键可导致大
