Abstract

Sulfated zirconia and SZ/MCM-41 were used as catalysts for the synthesis of β-aminoalcohols via epoxide aminolysis. Sulfated zirconia was prepared by sol-gel andSZ/MCM-41 was obtained by impregnation. Solid catalysts were characterized by XRD,SEM-EDS, UV-Vis, FT-IR pyridine desorption and Nitrogen physisorption. Both acidmaterials were useful as catalysts, even when they were recycled several times. The β-aminoalcohols were characterized by FT-IR, 1H- and 13C-NMR and GC-MS.
Keywords: Sulfated zirconia; SZ/MCM-41; β-aminoalcohols; oxirane; solventless reactions. Sulfated zirconia; SZ/MCM-41; β-aminoalcohols; oxirane; solventless reactions.
