| 摘 要： | ECR-1具有十二元孔道, 其通常是在有机模板存在下合成的, 我们曾报道了在无有机模板剂的条件下合成沸石ECR-1, 本文报道在无有机模板剂存在的条件下Y沸石水热转晶为沸石ECR-1的研究结果. 因为Y沸石具有合成简单、价格低廉和不使用有机模板等特点, 所以对由Y沸石转晶为ECR-1的研究, 对其在工业上的应用具有重要意义.

| Abstract: | Aluminosilicate zeolite ECR-1 was successfully obtained under hydrothermal condition at 100 ℃ by hydrothermal phase transition of zeolite Y in the absence of organic template. When n(Na2O)/n(SiO2) ratio in the starting aluminosilicate geln(SiO2)∶n(Al2O3)∶n(Na2O)∶n(H2O)=10∶1.0∶2.5—3.3∶200] was 0.33, the phase transition from zeolite Y to zeolite P occurred. However, when the n(Na2O)/n(SiO2) ratio was 0.25, zeolite Y was converted into zeolite ECR-1. In this case, zeolite Y was served as nutrient for the crystallization of zeolite ECR-1. |
