Solid catalyst of Ca@Al-Bentonite was prepared by modifying natural bentonite which collected from Bogor, Indonesia via pillarization of Al and wet impregnation of Ca particles. The catalyst was characterized by means of FTIR, XRD, XRF and BET surface area. The catalyst is successful to use for Aldol condensation in chalcone synthesis.
