Dimethyl Carbonate in the Supercages of NaY Zeolite: The Role of Local Fields in Promoting Methylation and Carboxymethylation Activity

Insight into the catalytic activity of NaY zeolite in dimethyl carbonate based methylation and carboxymethylation reactions is provided by a combination of vibrational spectroscopy and DFT‐based computational methods. The enhanced activity and selectivity is due to the electric fields present in the...

Zusammenfassung:Insight into the catalytic activity of NaY zeolite in dimethyl carbonate based methylation and carboxymethylation reactions is provided by a combination of vibrational spectroscopy and DFT‐based computational methods. The enhanced activity and selectivity is due to the electric fields present in the confined spaces of the supercages (see picture).
