摘　　要：通过不同方法,优化Sodalite沸石的晶化过程。采用加入过硫酸钠的方法,以及不同硅铝比配比的方法,测试不同时间Sodalite沸石的晶化效果。采用X-射线衍射(XRD)表征不同时间Sodalite沸石的晶化程度。结果表明,加入过硫酸钠后,Sodalite沸石的晶化速度明显加快,且以硅铝比为0.23的配比进行晶化,可以加快Sodalite沸石的晶化。此研究对高效合成沸石分子筛具有重大意义。The crystallization process of Sodalite zeolite was optimized by different methods. The crystallization effect of Sodale zeolite at different times was tested by the method of adding sodium persulfate and the different ratio of silicon to aluminum. The degree of crystallization of Sodale zeolite at different times was characterized by X-ray diffraction (XRD). The results showed that the crystallization rate of Sodale zeolite was obviously accelerated after the addition of sodium persulfate, and the crystallization rate of Sodolite zeolite was also accelerated at the silicon-to-aluminum ratio of 0.23. This study is of great significance for efficient synthesis of zeolite molecular sieves.
