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。
