摘要： 成功地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，其合成温度为120 oC，反应时间为4天，这与传统的无有机模板合成需要14天的反应时间相比，其生长周期大大缩短，该现象归属于它们的晶体生长机理的区别. 进一步，通过红外光谱、氮气吸附、扫描电镜、ICP及核磁等表征手段对产品的物理化学性能进行了系统表征，同时以异丙苯裂化作探针反应考察了产品的催化裂化性能.

Abstract: Aluminosilicate ECR-1 zeolite with 12-membered channels was successfully synthesized at 120 ?C for 4 days in the absence of organic templates. Compared with ECR-1 synthesized at 100 ?C for 15 days, the crystallization of ECR-1 at 120 ?C is very fast (4 days), which are reasonably related to their difference in synthesis mechanism. Furthermore, a series of techniques such as IR spectroscopy, N2 isotherm, SEM micrograph, ICP analysis, 29Si NMR spectroscopy, and catalytic cracking of cymene were used to characterize ECR-1 zeolite, confirming the successful synthesis.

Key words: fast crystallization, organotemplate-free synthesis, ECR-1 zeolite, catalytic cracking of cymene.
