We report a novel method to increase the metal loading in SBA-15 silica matrix via direct synthesis. It was demonstrated through the synthesis and characterization of a series of molybdenum containing SBA-15 mesoporous silica catalysts prepared with and without diammonium hydrogen phosphate (DHP) as an additive. Catalysts prepared with DHP show a 2-3 times increase in incorporation of molybdenum in the silica matrix and pore size enlargement. The synthesized catalysts were characterized using nitrogen sorption, X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and inductively coupled plasma-optical emission spectroscopy (ICP-OES). The catalytic activity of catalysts prepared with DHP for alcoholysis of epoxides was superior than the catalyst prepared without DHP. Alcoholysis of epoxides was demonstrated for a range of alcohols and epoxides under ambient conditions in as little as 30 min with high selectivity.

A single-stage method for producing α-hydroxy ethers by oxidizing olefinic substrates with organic hydroperoxides and opening the resultant oxirane ring by means of monovalent or polyvalent alcohols wherein a molybdenum compound in combination with a compound selected from the group consisting of boron trifluoride, aluminum oxides, 1,8-diazabicyclo-[5.4.0]-undec-7-ene or 1,4-diazabicyclo-[2.2.2]-octane, and mixtures thereof is used as a catalyst system.
