Ferrierite zeolite crystals were successfully prepared by a long amine as 1,8-diaminoctane (DAO) as organic structure directing agent. By comparison, shorter amine, i.e. ethylenediamine (EN), was also used as OSDA. Results shows that the presence of DAO reduces the crystallization time and allows to obtain single FER-type crystals with smaller size and higher acidity, being these significant parameters to take into account when zeolites are applied in catalysis. The obtained samples were characterised with XRD, TG/DTA, SEM, N₂ adsorption/desorption, FTIR and ²⁷Al-NMR. In particular, TGA clearly shows that DAO may be accommodate in zeolite framework and theoretical modeling suggests a preferential location in the 10-MR ring channels.

以1,8-二氨基辛烷（DAO）作为有机结构导向剂，成功地制备了镁碱沸石分子筛。相比之下，较短的胺，即乙二胺（EN），也被用作OSDA。结果表明，DAO的存在减少了结晶时间，并允许获得具有较小尺寸和较高酸度的FER型晶体，这是在沸石中应用催化时要考虑的这些重要参数。用XRD，TG / DTA，SEM，N ₂吸附/解吸，FTIR和²⁷ Al-NMR对所得样品进行表征。特别地，TGA清楚地表明DAO可能被容纳在沸石骨架中，并且理论模型表明在10-MR环形通道中存在优先位置。
