| 摘 要： | 以十六烷基三甲基溴化铵（CTAB）和Triton X-100（TX-100）混合表面活性剂为模板剂,正硅酸乙酯（TEOS）为硅源,采用水热法合成了MCM-48分子筛.实验中发现,晶化3 d后用醋酸调节溶液pH值的方法可有效提高MCM-48分子筛的产率；同时采用混合表面活性剂使模板剂的利用效率达到了6.0 TEOS/1.0 Surf (摩尔比）,并通过XRD、N2-吸附/脱附和TG-DSC等测试手段对产物的结构性能进行了表征.

| Abstract: | Using mixed surfactants cetyltrimethylammonium bromide (CTAB) and Triton X 100 (TX 100) as co template and tetraethylorthosilicate (TEOS) as silica source,MCM 48 molecular sieves were hydrothermally prepared. The yields of MCM 48 molecular sieves could be considerably increased by adjusting pH of the solutions which had been statically crystallized for three days,at the same time the utilizing efficiency of the mixed surfactants was much higher than thatof only CTAB as template. |
