ABSTRACT: Direct aldol reactions have been successfully performed using aromatic
aldehyde and cyclic ketone in nonpolar solvent by using immobilized
picolylamine on zirconia as a catalyst, in a double walled batch reactor. The
prepared catalyst was characterized by SEM, XRD and
FT-IR. FT-IR peaks reveal the presence of picolylamine on the surface of
zirconia. The catalyst shows excellent catalytic activity in aldol reaction of
cyclohexanone with benzaldehyde in cyclohexane giving 2-hydroxyphenylmethylcyclohexanone
(55.7% yield) in 4 hr at 80?C. Furthermore, the catalyst is recoverable by simple filtration and
could be used several times without significant loss in activity.
