甲基安非他明及杂质的气相色谱／质谱分析

利用ＤＢ－５弹性石英毛细管柱气相色谱／质谱联用技术分析公安人员缴获非法生产甲基安非他明粗产品，其中含有甲基安非他明８３％，及主要杂质１－苯基丙酮１３．３６％和２－甲亚胺基－１－基基丙烷１．３３％。此外还检测到 了甲基安非他明的分解产物１－丙烯基苯０．１１％、２－丙烯基苯０．０３％和环丙基苯０．０１％等。据此我科可以判断，该甲基安非他明是从１－苯基丙酮和甲胺反应再经催化氢化合而得。

Analysis of Methamphetamine and Its Impurities by Gas Chromatography/Mass Spectrometry

The clandestine manufacture methamphtamine is analyzed by GC/MS with DB-5 silica capillary column. This product contains methamphetamine 83. 00%, and main impurities as lphenylacetone 13. 46% and 2- Methylimino- 1 - phenylpropane 1. 3 3 %. The decomposition products of methamphetamine are also detected, they are: 1-propenylbenzene 0. 11 %, 2-propenylbenzene 0. 03% and cyclopropylbenzene 0.01 %. We can deduce that this methamphtamine manufactured clandestinely is synthesized from Phenylacetone and methylamine by catalytic hydrocessing because this raw methamphetamine contains phenylacetone and 2- methylimino- 1 -phenylpropane.
