摘要 在室温和一个大气压下 ,利用气相色谱和光离子色谱研究了空气中异丙醇与OH自由基和Cl的反应产物 .其主要产物为丙酮、乙醛和甲醛 .对于OH自由基与异丙醇的反应 ,丙酮与乙醛的产率分别大于 81 6%和 6 6% ;对于异丙醇与Cl的反应 ,丙酮和乙醛的产率分别为 78 5± 4 6%和 1 1 7± 1 0 % .结合光氧化反应主要产物 。 The primary products for the photooxidation of isopropanol initiated by OH radicals and Cl atoms were analyzed by GC FID and GC PID.The experiments were carried out at room temperature and 1 atm.Acetone,acetaldehyde and formaldehyde were the major primary products for both photooxidations.The product yields of acetone and acetaldehyde for the reaction of OH radicals with isopropanol were more than 81 6% and 6 6%,respectively;while the two product yields for the reaction of Cl atoms with isopropanol were 78 5±4 6% and 11 7±1 0%,respectively.The mechanisms of isopropanol photooxidation were also discussed.
