在无有机模板剂的条件下快速合成了硅铝沸石分子筛ECR-1,合成温度为120℃,反应时间为4 d,与传统的无有机模板合成反应时间(14 d)相比,其生长周期大大缩短,这是由它们的晶体生长机理不同所致.通过红外光谱、氮气吸附、扫描电镜、ICP及核磁共振谱等对产品的物理化学性能进行表征,以异丙苯裂化作为探针反应考察了样品的催化裂化性能.%Aluminosilicate ECR-1 zeolite with 12-membered channels was synthesized at 120 ℃ for 4 d in the absence of organic templates. Compared with ECR-1 synthesized at 100 ℃ for 14 d, the crystallization of ECR-1 at 120 ℃ is very fast (4 d), which are reasonably related to their difference in synthesis mechanism (120 ℃: a spontaneous nucleation process; 100 ℃: a crystal transformation process). Furthermore, a series of techniques such as IR spectroscopy, N2 isotherm, SEM, ICP, 29Si NMR spectroscopy, and catalytic cracking of cymene were used to characterize ECR-1 zeolite. The results show that crystallization of ECR-1 is greatly impacted by the synthesis temperature under organic template-free condition. For its catalytic property, the one dimension channel was the reason for the fast deactivation.
