The catalytic performances of dealuminated clinoptilolite in the vapour-phase condensation of acetaldehyde and formaldehyde were investigated. The activity of dealuminated clinoptilolite in terms of the overall conversion of the acetaldehyde is comparable with that of the cation-exchanged forms (Na+, Ni2+, Fe3+). The dealumination process of clinoptilolite exhibits a favourable effect on the catalytic selectivity toward crotonaldehyde formation.
