In situ FT-IR studies on formation of H-bonded alcohol adducts and their role in the mechanism of cyclopentanol etherification
Mechanistic studies play a key role of understanding how specified reaction conditions and/or properties of the catalyst itself can be tuned to optimize catalyst activity and selectivity towards desired product of particular reaction. The presentation will focus on FT-IR qualitative analysis of H-bonded methanol/cyclopentanol adducts formed by interaction with acid sites (more/less accessible for the substrate) located in MFI zeolites and their role in the mechanism of cyclopentanol etherification.
speaker: Mgr. Ondřej Veselý
Reverse ADOR Approach: Reconstruction of UTL zeolite from layered IPC-1P material
The Assembly-Disassembly-Organisation-Reassembly (ADOR) transformation of the UTL zeolite has led to the discovery of numerous new zeolite structures (PCR, OKO, *PCS, IPC-7, IPC-9, IPC-10); however, these daughter structures have only smaller pore size than the parent UTL. We have developed a method to artificially increase the spacing of layered intermediate IPC-1P by intercalating organic species and to reconstruct the double four rings (D4R) between layers, thus transforming IPC-1P back into the parent UTL zeolite.
