- Description
- Aluminophosphate incorporated with transition metals (Co, Cu, Fe, V) were synthesized by co-precipitation method. The synthesized materials were characterized by different techniques (pXRD, FT-IR, N2 adsorption-desorption, NH3-TPD) to understand the structural and textural properties. The incorporation of transition metal into aluminophosphate plays an important role in designing the surface properties like pore size, surface area, and surface acidity. The materials were studied as a catalyst for the synthesis of tetrahydroquinolin-5-(1H)-ones by a one-pot cyclocondensation reaction of dimedone, substituted benzaldehydes, 4-fluoro/4-nitro phenyl acetonitrile, and ammonium acetate in ethanol at 25 C. The structures of the compounds were identified and confirmed by FT-IR, 1H NMR, 13C NMR and ESI-MS spectral data. The mesoporous nature of vanadium aluminophosphate (VAlP) along with a uniform pore size distribution, high surface acidity, surface area attributes to its high catalytic activity when compared to pure aluminophosphates. 2020
