The hydroxylation reactions of Ethyl vinyl ether (cas 109-92-2) (EVE) in the present of O2 and NO are analyzed by using MPWB1K/6-311++G(3df,2p)//MPWB1K/6-31+G(d,p) level of theory. According to the calculated thermodynamic data, the detailed reaction mechanisms of EVE and OH are proposed. All of the ten possible reaction pathways are discussed. The major products of the title reaction are ethyl formate and formaldehyde, which is in accordance with experimental detection. The rate constants of the primary reactions over the temperature of 250–400 K and the pressure range of 100–2000 Torr are computed by employing MESMER program. At 298 K and 760 Torr, OH-addition channels are predominate and the total rate constant is ktot = 4.53 × 10−11 cm3 molecule−1 s−1. The Arrhenius equation is obtained as ktot = 6.27 × 10−12 exp(611.5/T), according to the rate constants given at different temperatures. Finally, the atmospheric half life of EVE with respect to OH is estimated to be 2.13 h.
