H3O+（H2O）n（n=0～4）与甲醇、乙醇反应的实验研究
Experimental study on reaction of H3O+（H2O）n（n= 0-4） with methanol and ethanol
【摘要】 在流动余辉质谱装置上,利用He的空心阳极放电产物与H2O反应制备了反应物离子H3O+(H2O)n(n=0-4),并观察了H3O+(H2O)n(n=0-4)与CH30H、C2H5OH反应的产物离子,对它们进行了归属,分析了各种产物离子形成的离子-分子反应机制。
【Abstract】 By the reaction of water vapor with He+ and He* which were generated by hollow cathode discharge of helium, H3O+(H2O)n(n= 0-4) was produced. We studied the reactions of H3O+(H2O)n(n= 0-4) with methanol and ethanol in a flowing afterglow mass spectrometer. Various ionic products were identified. They were formed by proton-transfer, ligand switching . association and condensation reactions.
