Discussion

Characterization of a novel catalyst improved conversion and selectivity in alkylation of 1,2,4-trimethylbenzene with methanol.

The catalyst achieved a 50.7% conversion for 1,2,4-trimethylbenzene and 82.4% selectivity for 1,2,4,5-tetramethylbenzene.
Characterization revealed optimal physicochemical properties linked to catalyst performance during the reaction.
Using PDDA and TPAOH templates, the catalyst demonstrated a unique structure with a silica-rich core and catalytic shell.
The findings may indicate that such catalysts could provide efficient catalytic micro-environments for alkylation reactions.

Dong et al. (2025) studied this question.
