以氧化铝和硅酸钠为骨架的铝硅源、十六烷基三甲基溴化铵（ＣＴＭＡＢ）为模板剂，用水热法合成超大孔ＭＣＭ－４１分子筛，并对合成过程的主要影响因素进行了考察，结果表明晶化温度过低，形成ＭＣＭ－４１分子筛速度慢，温度过高，会破坏模板分子之间形成胶棒的内聚力。形成ＭＣＭ－４１分子筛还需适当的ＣＴＭＡＢ／Ｈ２Ｏ、碱度、Ｈ２Ｏ／ＳｉＯ２等条件，否则会降低结晶度甚至于生成其它杂晶。 Alumina and sodium silicate as the framework of the aluminum-silicon source, cetyltrimethylammonium bromide (CTMAB) as a template agent, hydrothermal synthesis of large-pore MCM-41 molecular sieve, and the synthesis of the main influencing factors The results show that the crystallization temperature is too low, forming MCM-41 molecular sieve slow, the temperature is too high, will destroy the cohesion between the template molecules formed glue stick. The formation of MCM-41 molecular sieve also need appropriate CTMAB / H2O, alkalinity, H2O / SiO2 and other conditions, otherwise it will reduce the degree of crystallinity and even the formation of other heterocrystals.
