Disproportionation of trimethyl benzenes over large pore zeolites: catalytic and adsorption study
TL;DR: The effect of the structure of large pore zeolites of Mordenite, beta, L and Y types on the activity, selectivity to xylenes and time-on-stream stability was investigated in trimethyl benzene disproportionation as discussed by the authors.

Pyrrole as a Probe Molecule for Characterization of Basic Sites in ZSM-5: A Combined FTIR Spectroscopy and Computational Study
TL;DR: In this article, the interaction of pyrrole with alkali metal ion exchanged ZSM-5 (Li+, Na+, K+, Rb+, and Cs+) was studied by the combination of FTIR spectroscopy and the computational hybrid quantum mechanics/interatomic potential function method describing the role of the aluminum framework content and aluminum distribution, pyr role coverage, cation size, and cation coordination type.

Activation of reactants by hydroxyl groups of solid acids. An FTIR study
Josef Kotrla,Ludmila Kubelková +1 more
TL;DR: In this paper, the FTIR spectra of acetonitrile (AN), pyridine (Py), and acetone (AC)adsorbed at room temperature on the zeolite in sequence HX HY/2.2, HY/ 2.5, HM and HZSM-5 were employed for the discussion of the proton transfer between zeolites bridging hydroxyls and adsorbed acetone.

Pyridinium Ions - New Probe for Basic Sites of Solid Acids
TL;DR: In this paper, the hydrogen bonding interactions of the pyridinium ion (PyH + ) with the deprotonated skeleton of acid zeolites were studied using Fourier transform infrared (FTIR) spectroscopy and quantum chemical ab initio calculations.
