Summary, etc. The synthesis of jasminaldehyde over zirconia based acid-base bifunctional catalysts has beem reported. Solid catalysts such as zirconia, ceria and ceria-zirconia have been prepared and characterized for their physico-chemical properties such as surface area, surface acidity, surface basicity, crystalinity, functionality and elemental analysis by using techniques such as BET, NH<sub>3</sub>-TPD, CO<sub>2</sub>-TPD, PXRD, FT-IR and ICP-AES. The solid catalysts are evaluated in the aldol condensation of benzaldehyde and 1-heptanal to synthesize jasminaldehyde. Reaction conditions such nature of the catalyst, weight of the catalyst, molar ratio of the reactants, reaction temperature and reaction time have been studied to get a set of optimized reaction conditions under which highest possible yield of jasminaldehyde could be obtained. Reactivation and reusability of these solid catalysts is also studied. Ceria-Zirconia mixed oxide is found to be highly active and efficient bifunctional catalyst for the selective synthesis of jasminaldehyde. This catalyst is found to be reusable atleast for 6 reaction cycles without much loss of its catalytic activity.
