摘要：

Zeolite ZSM-23 was synthesized in the presence of pyrrolidine. An increase of the synthesis time and the crystallite size with decreasing alkalinity (NaOH content) suggests that not only hydroxyl ions but also sodium ions play an important role in the nucleation of ZSM-23. One of the synthesized samples was characterized by means of selected catalytic test reactions, viz. hydrocracking of butylcyclohexane (determination of the Spaciousness Index, SI) and the isomerization and hydrocracking of n-decane. The observed selectivities suggest that the effective pore width of ZSM-23 is slightly smaller than that of ZSM-5.
