Ethylene oxide is an intermediate frequently formed during the combustion of hydrocarbons, in both the low- and high-temperature regimes. The oxidation of ethylene oxide (C{sub 2}H{sub 4}O) has been investigated in a jet-stirred reactor at high temperature (800--1,150 K) in the pressure range 1 to 10 atm for several equivalence ratios (0.5 {le} {phi} {le} 2). The concentration profiles of O{sub 2}, H{sub 2}, CO, CO{sub 2}, CH{sub 4}, C{sub 2}H{sub 2}, C{sub 2}H{sub 4}, C{sub 2}H{sub 6}, C{sub 3}H{sub 6}, C{sub 3}H{sub 8}, CH{sub 3}HCO, and C{sub 2}H{sub 4}O were obtained by probe sampling and gas-chromatographic analysis. Ethylene oxide oxidation in these conditions was modeled using a comprehensive kinetic reaction mechanism. The proposed mechanism is able to reproduce experimental data obtained in the high-pressure, jet-stirred reactor and also ignition delays measured in a shock tube (1,070--1,330 K, 5--15 atm, 0.36 {le} {phi} {le} 3.2). The same mechanism has also been validated for the oxidation of CH{sub 4}, C{sub 2}H{sub 2}, C{sub 2}H{sub 4}, C{sub 2}H{sub 6}, CH{sub 3}HCO, C{sub 3}H{sub 6}, C{sub 3}H{sub 8}, 1-butene and n-butane, as well as mixtures of CH{sub 4} with C{sub 2}H{sub 6} and/or C{sub 3}H{sub 8} under the same conditions.
