Abstract
The acid properties of UL-ZSM-5 materials were studied and found to be improved by a treatment in aqueous ammonia solutions. The catalytic properties in the aldol condensation of acetaldehyde with formaldehyde were examined after this treatment. The UL-ZSM-5 were found to be less sensitive to coke deactivation than ZSM-5 of comparable Si/Al ratio and more active than the mesostructured precursor.
