摘要：
The Diels-Alder reaction between isoprene and methyl acrylate over several zeolites was thoroughly investigated. ZSM-5 zeolites provided the highest productivity in methyl 4-methylcyclohex-3-enecarboxylate isomer, achieving 0.219mmol product per mmolH(+) in 1hour. In addition, this study highlights the influence of ZSM-5 zeolite's BrOnsted acidity and crystal size on its performance in the Diels-Alder reaction. An optimal configuration between the two reactants within the medium-pore-sized ZSM-5 framework is obtained, thus suggesting the presence of a confinement effect.
