摘要:

目的 优化并建立分析1-苯基-2-丙酮(1-phenyl-2-propanone,P-2-P)和3,4-亚甲基二氧苯基-2-丙酮(3,4-methylenedioxyphenyl-2-propanone,MDP-2-P)前体物质的GC-MS、LC-MS和红外光谱法。 方法 采用GC-MS、LC-MS和红外光谱法对11种P-2-P、MDP-2-P前体物质进行分析,并对溶剂、进样口温度等关键技术参数进行优化。 结果 3-氧-2-苯基丁酸甲酯(3-oxo-2-phenylbutyl methyl ester,MAPA)等物质结构中含有酯键,易发生酯交换反应,溶剂应避免选用醇类试剂,建议选用乙腈等非醇类溶剂。GC进样口温度高于170 ℃时MAPA等物质会发生降解,建议降低进样口温度至170 ℃。2-甲基-3-苯基缩水甘油酸钠(BMK sodium glycidylate)和2-甲基-3-[3,4-(亚甲二氧基)苯基]缩水甘油酸钠(PMK sodium glycidylate)在GC-MS分析时不出峰,建议采用红外光谱法进行检测。 结论 本研究建立了可对11种P-2-P和MDP-2-P前体物质进行准确定性分析的GC-MS、LC-MS和红外光谱法,可为相关案件中该类物质的检测提供技术支撑。

Abstract:

Objective To optimize and establish GC-MS, LC-MS, and infrared spectroscopy (IR) methods for analyzing 1-phenyl-2-propanone (P-2-P) and 3,4-methylenedioxyphenyl-2-propanone (MDP-2-P) precursors. Methods Eleven precursor substances of P-2-P and MDP-2-P were analyzed by GC-MS, LC-MS and IR methods, some key analytical parameters, such as solvent and injection temperature, were optimized. Results Substances such as 3-oxo-2-phenylbutyl methyl ester (MAPA) contain ester bonds in their structures were prone to ester exchange reactions. Therefore, alcohol solvent should be avoided to prevent the esterification. Instead, non-alcohol solvents, such as acetonitrile, were recommended. Substances such as MAPA that may undergo decomposition at the gas phase injection port temperature exceeded 170 ℃. It was recommended to lower the temperature of the injection port to 170 ℃. For substances that did not show peaks during GC-MS analysis, such as 2-methyl-3-phenylglycidic acid sodium salt (BMK sodium glycidylate) and 2-methyl-3-[3,4-(methylenedioxy)phenyl]glycidic acid sodium salt(PMK sodium glycidylate), it was recommended for IR detection. Conclusion This study established GC-MS, LC-MS and IR methods that can accurately qualitatively analyze eleven P-2-P and MDP-2-P precursors, which can provide technical support for the detection of such substances in related cases.
