环氧丙烷均相热分解的反应机理在文献中存在着争论。Thompson和Meissner认为环氧丙烷先异构化为丙醛,生成的激活丙醛分子进一步反应得到一氧化碳、乙烯、乙烷和氢等产物。Lossing等根据在1100K高温下进行的均相热分解反应推断环氧丙烷在裂解过程中首先异构化为丙酮。Benson从热化学动力学的观点出发,认为环氧丙烷因活化形式的不同可以生成两种形式的双启由基,它们分别产生丙醛和丙酮。我们设计的热絲真空反应器曾应用于环氧乙烷在银絲表面的分解反应,发现同均相 The reaction mechanism of homogeneous thermal decomposition of propylene oxide is controversial in the literature. Thompson and Meissner think propylene oxide isomerization first to propionaldehyde, the resulting activation of propionaldehyde molecules further reaction to carbon monoxide, ethane, ethane and hydrogen and other products. Lossing et al. Concluded from the homogeneous thermal decomposition reaction carried out at a temperature of 1100K that propylene oxide was isomerized first to acetone during cracking. Benson From the standpoint of thermochemical kinetics, it is believed that propylene oxide, due to its different activated forms, can produce two forms of bicyclic starting groups that produce propionaldehyde and acetone, respectively. We design the hot wire vacuum reactor has been used in ethylene oxide decomposition reaction in the silver surface and found the same phase
