| 英文摘要 | The n-pentyl peroxy radical (C5H11O2) is a crucial intermediate in the oxidation process of n -pentane, playing an important role in the chain propagation and termination of atmospheric radicals under low NOX conditions. The products from the self -reaction of C5H11O2 were detected online by a microwave discharge fast -flow reactor combined with a vacuum ultraviolet photoionization mass spectrometry in this work. The results indicated three product channels in the self -reaction of C5H11O2 , corresponding to alkoxyl radicals (C5H11O), carbonyl compounds (C5H10O) and organic alcohol (C5H11OH), as well as dimeric products (C5H11OOC5H11 ). Further research was conducted to determine the original channels of the products through reaction kinetics experiments, revealing the self -reaction mechanism of C5H11O2 by comparing the experimental and the simulated results of the main products. The dimeric product C5H11OOC5H11 , formed in the self -reaction of C5H11O2 , was measured online for the first time, predicting its channel branching ratio to be approximately 10%. The molecular and ionic structures of the product were determined with the help of quantum chemical theoretical calculations. |
