Abstract The liquid-phase Prins condensation between i-butene and formaldehyde was studied over parent and Mg-modified MFI and BEA zeolites with low Si/Al ratios. High catalytic activity and selectivity toward isoprene were obtained using the H-BEA zeolite. The H-MFI zeolite was confirmed as a highly selective catalyst for 3-methylbut-3-ene-1-ol production via Prins condensation. The influence of Mg-ion-exchange treatment on the catalytic behavior of the zeolites was studied; modification of BEA led to significant changes in the catalytic behavior, while Mg-MFI and H-MFI showed similar conversion of formaldehyde and similar product distribution.
