Abstract
SAPO-11 synthesized by the conventional static hydrothermal method at optimized temperature. The calcinations and crystallization gives fine crystallizations. SAPO-11 again calcinated with zirconium nitrate and obtained product was characterized by IR and powder XRD. The catalyst was applied for the synthesis of chalcones via aldol reaction. The reaction proceeds with good yields. The catalyst was recycled and found suitable for reactions. The formed product was characterized by IR, NMR spectroscopy.
