Abstract:
The fragmentation pathways of O-trimethylsilyl (TMS) ethers of long-chain bases were studied by the linked-scan technique and exact mass measurements of the characteristic ion of O-trimethylsilyl long-chain bases detected by gas chromatography combined with electron-impact mass spectrometry. The results indicate that there are three pathways: the M+ - 15 (CH3) - 90 (TMSOH) - 74 [OSi(CH3)2] series, the M+ - 103 (CH2OTMS) - 90 (TMSOH) series and the M+ - 132 (CHNH2CH2OTMS) series.
