In the study of non-isothermal crystallization kinetics, we found that the Avrami constants were enhanced with the increase of the amount of the modified MMT at 10 ℃/min and 30 ℃/min. But it decreased with the increase of the amount of the modified MMT while the cooling rate increase to 50 ℃/min. The crystallization rate constat k also increased with the increase MMT and it revealed that the crystallization rate of composites accelerated by the presence of MMT.

由非等温结晶动力学得知，复材之Avrami 常数n值在10℃/min与30℃/min时，会随著改质蒙脱土含量增加而上升，但是当降温速率提升至50℃/min时，则随著改质蒙脱土增加而下降，其结晶速率常数k值随著改质蒙脱土含量增加而上升，代表复材之结晶速度也会受到添加改质蒙脱土的影响而变快。

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。
