First, OFF and LTL single crystals were synthesized in different systems, such as traditional conditions, synthesis in the presence of F〓, and in the presence of pyrocatechol.

采用水热合成法，分别在传统体系、F〓体系和邻苯二酚体系中合成了第二类沸石中的OFF和LTL单晶，并考察了碱度、硅铝比、水量、晶化温度等对合成晶体形貌的影响。

Large single crystals were also obtained by using pyrocatechol as additive. It was shown by 〓Si-NMR and IR that Sipyrocatechol complex was formed in the reaction system.

在F〓体系中，F〓对铝源和硅源起络合和矿化作用，形成可溶性氟硅酸盐AlF〓〓、SiF〓〓络合物，然后缓慢水解成含氧氟硅酸盐络合物，它们再发生定向缩聚，提供了分子筛晶体生长所需的可溶性结构单元。
