摘　　要：对有机化学学习中"烃类不完全燃烧产生黑烟"的谜团进行解释,阐述了黑烟是一种由挥发性燃料在火焰中团聚产生的黑炭颗粒——烟炱,分析了烟炱以多环芳烃为母核的分子结构,讨论了共振稳定自由基的链式反应并团聚形成烟炱的机理。黑炭在环境科学、能源化学、有机化学等领域有重要的影响意义。因此,期望本文能为现有的有机化学教材作拓展补充,为相关教学工作提供借鉴意义。This article aims to explain the mysterious phenomenon of black smoke formed in the incomplete combustion of hydrocarbons,which is usually referred to in the study of organic chemistry.This black smoke is actually one kind of black carbon whose name is soot.Its structure is based on polycyclic aromatic hydrocarbons,and it is possibly formed from clustering of resonance-stabilized radicals by radical-chain reactions.In fact,black carbon has extremely vital significance in environmental science,combustion chemistry,organic chemistry,and so on.So this article is expected to provide a supplementary for the present textbooks and learning of organic chemistry.
