Abstract:通过在溶胶-凝胶过程中添加适量成核促进剂NaH2PO4进行凝胶控制,经一步水热晶化法合成出具有中空结构小晶粒ZSM-5分子筛,并通过XRD、FTIR、SEM、TEM、激光粒度分析和N2吸附-脱附等手段对其结构进行了表征.表征结果显示,成核促进剂的添加使得合成的ZSM-5分子筛形貌更加规则,晶粒大小更为均一,晶粒出现中空结构.在2-甲基萘烷基化合成2,6-二甲基萘的过程中,制得的中空ZSM-5分子筛表现出较好的稳定性、活性和选择性.在反应温度400℃、2-甲基萘重时空速0.5 h-1的条件下,2-甲基萘初始转化率大于28％；反应12h后仍保持在25％以上,2,6-二甲基萘收率最高可达10.5％.
