| 摘 要： | 本文在840～950K范围内应用单脉冲化学激波管测定环氧氯丙烷的裂解反应动力学。实验结果表明,反应不是通过链反应机理。主要反应产物有:CH≡CH,H—(?)—H,CH_2=CH_2,CO,CH_2=CH—CHO和HCl。推测HCl的消去反应是环的断裂之前,消去反应是通过四中心过渡态进行。测定了反应机理中各步反应的速率常数。

| Abstract: | The chemical kinetics for the pyrolysis of epichlorohydrin was studied by single pulse shock tube in 840-950K. The results show that the reaction doesn't undergo aradical chain decomposition. The major products are CH(?)CH, CH2=CH2,CO, CH2=CH-CHO and HCl. It is supposed that the reaction for the cycle opening is preceded by the elimination of HCl which involves a four-center transition. The rate constants for the reactions were measured. |
