In Chapter 5,the pyrolysis of substituted six-membered ring model compound 4-methyl pyridine has been investigated.Instead of detail theoretical analysis of the reaction mechanism,the general results have been proposed from the products distribution and the combination of the pyrolysis investigation of its analogous pyridine.The major products are H_2,C_2H_2,C_4H_2,C_3H_3N and HCN,here HCN is not a primary initial product at low extent of decomposition.The mole fraction profiles of products have been obtained from the near threshold ionization.The pyrolysis of 4-methyl pyridine is initiated from the methyl abstraction and hydrogen abstraction procedures which are associated with the understanding of the soot formation and the NOX precursor correspondingly.

主要产物为H_2，C_2H_2，C_4H_2，C_3H_3N和HCN，其中HCN为非低温时的热解产物；通过近阈值电离并导出物种随温度变化的摩尔分数曲线，更详细地定量地描述了产物随温度的变化。4-甲基吡啶热解主要从母体脱甲基和脱氢两个初始反应出发，一种趋势是形成大质量数的苯并或杂环的多环化合物，有助于了解炭黑形成过程中的复杂化学过程；另一趋势是开环生成小的碳氢和腈类物质，实验得出的含氮物质的种类及随温度变化有助于了解NO_x的前驱物质的形成及其变化规律。
