system. Pyrolysis of 4-phenyl-1-butanol 3, 2-methyl-3-phenyl-1-propanol 4, and 2-methyl-3-phenylpropanoic acid 5 was also studied, and results were compared with those obtained for compounds 1–3. The pyrolytic reactions were homogeneous and followed a first-order rate equation. Analysis of the pyrolysate showed the products to be phenol (from 1a to 1c), thiophenol (from 2a to 2c), and toluene (from 3 to
制备了含有伯醇、仲醇和叔醇的
3-苯氧基-1-丙醇 1a-c 和 3-苯
硫基-1-
丙醇 2a-c,并在静态反应系统中进行气相热解。还研究了 4-苯基-
1-丁醇 3、2-甲基-3-苯基-1-
丙醇 4 和 2-甲基-
3-苯基丙酸 5 的热解,并将结果与化合物 1-3 的结果进行了比较. 热解反应是均匀的并且遵循一级速率方程。对热解产物的分析表明产物是
苯酚(从 1a 到 1c)、
苯硫酚(从 2a 到 2c)、
甲苯(从 3 到 5)和羰基化合物。九种研究化合物中每一种的动力学结果和产物分析都根据消除途径的合理过渡态进行了合理化。© 2007 Wiley Periodicals, Inc. 40: 51–58, 2008
