Sulfated ZrO₂ Supported on HMS Mesoporous Silica for Catalytic Epoxidation of Soybean Oil

Abstract:

Sulfated zirconia supported on HMS mesoporous silica (SZ-HMS) was prepared and evaluated by catalytic epoxidation of soybean oil. The preparation procedure of SZ-HMS included soaking of HMS with ZrOCl₂, and then sulfating with H₂SO₄. The samples were characterized by IR, XRD, and N₂-adsorption. SZ-HMS kept the typical mesoporous crystalline as well as pore structure and exhibited an excellent catalytic performance for the epoxidation of soybean oil. The best catalytic activity, 4.4 of epoxy value, is acquired over the SZ-HMS sample prepared by 0.2 mol/L of ZrOCl₂ concentration, 0.75 mol/L of H₂SO₄ concentration, and 823 K of calcination temperature.
