摘要: 具有ZSM-5结构的含钛和含硼分子筛是催化性能良好的新型杂原子分子筛,可分别作为碳氢化合物的氧化反应[1]和制备高纯异丁烯的催化剂[2]。近年来,有关这2种分子筛的合成已见报道[1~4]。但其合成均采用碱性介质,成核和晶化都比较快,因此未能得到生长完美的杂原子ZSM-5型分子筛大单晶。

Abstract: The large single crystals of silica-rich, Ti-, B-ZSM-5 type zeolitescalled Titanozeosilite and Borozeosilite were synthesized in non-alkaline medium inthe presence of fluoride. The mechanism of the crystallization for the singlecrystals was investigated in the systems of SiO2-TiO2-(TPA)2O-NH4F-H2O and SiO2-B2O3-(TPA)2O-NH4F-H2O.
