Seven alkyl methylphosphonic acids, products of hydrolytic degradation of organophosphorus chemical warfare agents, were obtained with a high purity (mostly above 98%), with the aim of being applyed as future certified reference materials. Ethyl (EMPA), isopropyl (IMPA), pinacolyl (PMPA), butyl (BUMPA), isobutyl (IBUMPA), cyclohexyl (CHMPA) and 2-ethylhexyl (EHMPA) monoesters of MPA were synthesized
获得了七种烷基甲基膦酸,它们是有机磷化学战剂的水解降解产物,具有很高的纯度(大多高于98%),目的是用作将来认证的参考材料。合成了MPA的乙基(EMPA),异丙基(IMPA),频哪醇(PMPA),丁基(BUMPA),异丁基(IBUMPA),环己基(CHMPA)和2-乙基己基(EHMPA)单酯,并通过MS EI,FTIR和NMR进行了表征(1 H,13 C,31P),TLC以及衍生化后的GC和GC-MS。建立了在非衍生化烷基甲基膦酸的CP-FFAP CB柱上直接定量GC FID分析的条件。这是对游离烷基膦酸进行定向GC分析的首次成功尝试。确定了它们的化学纯度,并用GC-FID方法评估了其中一些的定量极限(LOQ)值。
