一、前言 碳化是一个芳香族化合物生长和缩聚的过程,一般来说是由小的芳香族结构缩聚成二维有序的芳香族稠环层面,最终达到三维有序的石墨。整个碳化过程极其复杂,但下面这些过程可以认为是芳香族碳氢化合物热解时的主要反应:a、C-H、C-C键断裂生成活泼的自由基;b、分子重排;c、热缩聚;d、芳香族化合物稠合;e、侧链脱氢。
I. INTRODUCTION Carbonization is a process of growth and polycondensation of aromatic compounds. Generally, polycondensation takes place from a small aromatic structure into a two-dimensionally ordered aromatic fused ring layer, and eventually reaches three-dimensionally ordered graphite. The entire carbonation process is extremely complicated, but the following processes can be considered as the main reactions during pyrolysis of aromatic hydrocarbons: a, CH, CC bond breaking generated lively free radicals; b, molecular rearrangement; c, thermal polycondensation; d , Aromatic compounds fused; e, side chain dehydrogenation.
