PROBLEM TO BE SOLVED: To provide a catalyst which can produce ethylene oxide with high activity and selectivity and to provide a production method of ethylene oxide by gas-phase oxidation of ethylene by a gas containing a molecular oxygen employing the same catalyst.;SOLUTION: The catalyst for producing ethylene oxide is obtained by making a carrier support as a main component of α-Al₂O₃, wherein an intensity of the infrared adsorption spectrum in the range of wave number of 3,150 to 3,800 cm^-1 is substantially zero in the infrared adsorption spectrum measured by the KBr tablet method. The production method of ethylene oxide is provided which employs the same catalyst.;COPYRIGHT: (C)2008,JPO&INPIT
