After this research work, we know that: HMCM-22 is a better catalyst of selecting naphthalene alkylation; Surface modification of zeolite Y is effective, but the effect of zeolite 3 is not evident and surface modification doesn"t suits mordenite; Surface modification doesn"t affect the frameworks and inner environments of zeolites, but only reduces diameter of orifice and overlays surface acidities; t-butanol is not suitable for alkylating agent of the reaction using modified zeolites as catalyst; Solvents with smaller molecular size are advantageous for naphthalene alkylation reaction using modified zeolites as catalyst, such as cyclohexane is better than decalin.

通过本论文的研究，我们知道：HMCM-22是萘择形烷基化反应较好的沸石之一；Y沸石的外表面改性效果较好，β沸石则效果不明显，而丝光沸石则不适于外表面改性；外表面改性不改变沸石的骨架结构和孔道内部环境，仅减小孔口直径和覆盖外表面酸性位；叔丁醇不适于作外表面改性沸石催化的反应的烷基化试剂，其反应活性很低，且选择性无明显提升；分子较小的溶剂更适于外表面改性沸石催化的反应，环己烷就明显好于十氢萘。

The same methods were used to study toluene dinitration, and the results indicated that the thermal runaway risks of these reactions were low too; prolonging dosing duration was helpful to the conversion of all nitrotoluene; decreasing the molar ratio of nitric acid to mononitrotoluene would make an insufficient conversion; among the given temperatures, rising reaction temperature couldn\'t markedly change the yield coefficient, but lead more heat generation and higher thermal runaway risk.

采用同样的方法对二段硝化反应进行研究，结果表明：二段硝化反应的热失控危险性也较低；延长加料时间，有利于反应完全；而随着硝酸与一硝基甲苯摩尔比的减小，硝化难以进行完全；在选定温度范围内升高温度，产物得率无显著变化，反而易导致放热加剧，增加体系的热失控危险。
