摘　　要：近年来,醇类的红外光化学反应及其红外多光子解离的研究日益受到人们的重视。Farneth等报道了用TEACO_2激光器引发气相异丙醇反应,得到丙烯产物。我们用CW-CO_2激光引发气相和液相异丙酮反应,主要得到丙酮,以及少量的丙烯,甲烷和CO。我们曾经研究了CW-CO_2激光引发NH_3+CH_3OH反应得到产物六次甲基四胺,而此产物是由CH_2O和NH_3反应生成的。据此,我们认为在无氧条件下。This paper reported CW-CO_2 laser induced reactions of 2-propanol in gas and liquid phases, respectively. The products of the reaction are acetone, propene, CO and CH_4. The main reaction pathway of 2-propanol at high excited state appears to be the dehydro- genation to form acetone and the minor reaction pathway is the dehydration to form pro- pene. Furthermore, the presence of CO and CH_4 in the reaction mixture showed that there was some secondary laser sensitive dissociation of acetone.
