研究了高硅沸石从 0–4 ROH（脂肪醇）：0.1–0.6 Na2O:0.002–0.02 Al2O3:SiO2:40–80 H2O 的结晶。成功合成了不同晶粒尺寸的丝光沸石单晶。在充分优化的条件下，获得了纯净、均匀、大的单晶。通过对合成态和质子化丝光沸石的氮吸附、29Si和27Al MAS NMR测量发现，合成态丝光沸石为小孔丝光沸石。
Crystallization of high-silica zeolites from 0–4 ROH (aliphatic alcohol):0.1–0.6 Na2O:0.002–0.02 Al2O3:SiO2:40–80 H2O was investigated. Single crystals of mordenite with different crystal sizes were successfully synthesized. Under well-optimized conditions, pure uniform and large single crystals were obtained. From nitrogen adsorption,29Si and27Al MAS NMR measurements of as-synthesized and protonated mordenites, it was found that as-synthesized mordenite is small port mordenite.
