Abstract:
A process for producing an oxirane compound by reacting an olefin and a hydroperoxide in the presence of a catalyst wherein said catalyst is obtained by gelling a silicon compound of the following formula (1) (silicon compound (1)), a silicon compound of the following formula (2) (silicon compound (2)) and a titanium compound in water, alcohol solvent or mixed solvent of water and alcohol, removing a solvent in the resulted gel by extraction with supercritical fluid, then, drying and silylating the resultant:Si(OR1)4â€ƒâ€ƒ(1) (R2)mSi(OR3)4âˆ’mâ€ƒâ€ƒ(2) (R1, R2 and R3 independently represent a hydrocarbon group having 1 to 20 carbon atoms and m represents an integer of 1 or 2).
