在SBA-1合成体系中添加醇类，研究了酸度、醇类烷基链长、合成温度和时间对分子筛合成的影响。增加原硅酸四乙酯 (TEOS)、十六烷基三乙基溴化铵 (CTEABr)、HCl 和 H2O 混合物中的醇浓度 (CmH2m+tOH)，当 m = 2 和 3 时，形成高度有序的 P6(3)/mmc 和 p6mm 相
The influence of acidity, alkyl chain length of alcohols, synthesis temperature and time on the molecular sieve synthesis by adding alcohols to the system for the SBA-1 synthesis were studied. Upon increasing the concentration of alcohols (CmH2m+tOH) in the mixture of tetraethyl orthosilicate (TEOS), cetyltriethylammonium bromide (CTEABr), HCl and H2O, highly ordered P6(3)/mmc and p6mm phases were formed when m = 2 and 3
