摘要
本文论述了一种新颖的分子筛合成方法——在非水体系中合成沸石分子筛,综述了利用多种仪器对非水体系合成的沸石的性能研究,表明非水介质同样能够提供沸石分子筛晶体成核和生长的良好环境,为定向合成某一催化反应所需的硅铝比沸石提供了可能性。非水体系合成沸石为沸石的固相晶化机理提供了一个有力的佐证。
The advances of new method to synthesize zeolites are expounded. It is discussed that the properties of zeolites which are synthesized in nonaqueous system were characterized by various techniqic methods. These results show that nonaqueous medium is a good dnviromlent to form zeolites.
