Effect of the addition of acidic and basic compounds on the catalytic behavior of exchanged zeolites in the alkylation of toluene with methanol

Catalytic performance of X molecular sieve modified by alkali metal ions for the side-chain alkylation of toluene with methanol

“…The catalysts for side-chain alkylation of toluene with methanol were studied extensively [1,[6][7][8][9][10][11][12][13]. It was reported that a good catalyst for side-chain alkylation should behave the properties of (1) sufficient base strength to dehydrogenate methanol to formaldehyde, (2) stabilization of adsorbed toluene and polarization of its methyl group, and (3) balanced sorption stoichiometry of the reactants [5].…”

“…However, there are many disadvantages associated with the traditional process for the production of styrene, including high costs, as well as high levels of energy consumption and environmental pollution resulting from the high reaction temperature and toxic nature of the raw materials [2]. To address these issues, there has been a recent increase in research directed towards the side-chain alkylation of toluene because it has the potential to provide a novel route for the production of styrene while avoiding the limitations associated with the traditional production process [3][4][5][6][7][8][9][10][11].…”
