【摘要】 本文以化学反应质谱法(RMS),负离子 FAB 和 EI 源为离子源,苯基硼酸(PBA)为反应试剂研究了某些二取代苯的位置异构体。结果表明,凡是邻二取代苯均出现十分明显的特征反应离子,以此可以确定邻二取代苯。更多还原

【Abstract】 In present paper,some disubstituted benzene isomers have been studied by reaction mass spectrometry (RMS) using phenylboronic acid (PBA),In negative ion FAB and EI mass spectra,the o-disubstituted benzene deriva- tives yield predominate characteristic ions on which these compounds may be distinguished from the m-or p-disubstituted isomers.更多还原
