摘要：

Si-VPI-5 crystals containing Si atoms in Si(4Al) environments are synthesized. The crystals contain occluded amine. It is protonated and neutralizes the residual negative lattice charges associated with the Si(4Al) sites. Calcined Si-VPI-5 is active in the isomerisation of decane and exhibits extra-large pore characteristics.
