摘要
本报告是关于质谱中六甲基苯和六(三氟甲基)苯的衰变序列-离子系列分析结果的报告,是关于苯和六氟苯离子系列文章的延续。与苯的质谱的6个离子系列相反,六甲基苯的质谱由11个离子系列组成。六甲基苯+质谱的前三个离子系列。M 1-3,包括淘汰组:ch3 +6。H), (c2h4 + 7)H)和(c3h6 + 5)H)与离子+ С 11h9, + С 10h7和+ c9h7的形成,这是甲基取代基在没有重排现有的六元环π -共轭的情况下发生的结果。最后四个系列的+。m8 -11离子是由中性分子c8h11和c9h13以及自由基分离形成的。c10h13和。c11h15,其中也保留了6元环。由于四个系列+。出现了+ c4h7 M /z 55、+ c3h5 M /z 41、+ c2h5 M /z 29和+ ch3m /z 15离子。两个中间系列
DECAY SEQUENCES - ION SERIES OF MASS SPECTRA HEXAMETHYLBENZENE AND HEXAKIS(TRIFLUOROMETHYL)BENZENE
: This report on the results of the analysis of decay sequences - ion series of mass spectra: hexamethylbenzene and hexakis(trifluoromethyl)-benzene, is a continuation of the article on the ion series of benzene and hexafluorobenzene. In contrast to the six ion series of the mass spectrum of benzene, the mass spectrum of hexamethylbenzene consists of eleven series of ions. The first three ionic series of the mass spectrum of hexamethylbenzene + . M 1-3 , including the elimination of groups: ( . CH 3 +6 . H), (C 2 H 4 + 7 . H) and (C 3 H 6 + 5 . H) with the formation of ions + С 11 H 9 , + С 10 H 7 and + C 9 H 7 - the result of agmentation of methyl substituents that occur without rearrangement of the existing π - conjugations of the six-membered ring. The four final series of + . M 8-11 ions are formed upon detachment of neutral molecules C 8 H 11 and C 9 H 13 , as well as radicals . C 10 H 13 and . C 11 H 15 , in which the 6-membered ring is also retained. As a result of four series + . M 8-11 , ions + C 4 H 7 m/z 55, + C 3 H 5 m/z 41, + C 2 H 5 m/z 29 and + CH 3 m/z 15 appear.
