| 摘 要： | INTRODUCTION ZSM-5 zeolite is a typical high silica zeolitewith MFI-type structure which makes ZSM-5 zeo-lite widely useful as catalysts in petroleum andpetrochemical industry. In recent years, the appli-cation of ZSM-5 is expanding into the synthesisfields of specialty and fine chemicals (Davis, 1998),such as the preparation of ethylene amines. The ex-cellent catalytic performance of ZSM-5 was noted(Hua and Hu, 2001). In most cases, the synthesis of ZSM-5 is ach-ieved…

| Abstract: | ZSM-5 zeolite was rapidly synthesized in system containing ethylenediamine from the initial gel: (5?8) Na2O: 44 EDA:Al2O3:100 SiO2:4000 H2O. The crystals were lath-shaped. The effect of pretreatment and alkalinity on crystallinity was investigated. The pretreatment of silicate source can cut down the crystallization time. Tuning the system alkalinity and controlling crystallization time can ensure forming of pure crystal. |
