Dealuminated Natural Zeolites for Applications
in Catalytic Processes with Formation of C-C Bonds
II. Aldol condensation over natural clinoptilolite modified by dealumination

Abstract:

The vapor-phase aldol condensation of acetaldehyde and formaldehyde over the natural volcanic tuff, dealuminated by acidic treatment, was studied. The condensation reactions were performed over a temperature range from 250° to 400°C. The catalytic properties were analyzed taking into account both, the influence of the reaction temperature and the effect of the acidic treatment applied to the natural volcanic tuff. Keywords: aldol condensation, dealumination, natural zeolites, clinoptilolite
