利用GC-MS对TDA/DEIP混合液的反应产物进行定性分析,确定了最佳的色谱、质谱条件,利用GC毛细管柱优良的分离效果和MS反映出的离子碎片、质荷比等数据信息,迅速确定了反应产物,对研究TDA/DEIP反应机理提供了充分的依据。充分发挥了气-质谱联用在未知物定性方面强大的分离-定性分析优势。
The reaction products of TDA / DEIP mixture were qualitatively analyzed by GC-MS, and the best chromatographic and mass spectrometric conditions were determined. Based on the excellent separation performance of GC capillary column and the ion fragment, mass-to-charge ratio and other data information reflected by MS, Rapid determination of the reaction products, to study TDA / DEIP reaction mechanism provides a sufficient basis. Give full play to the gas-mass spectrometry in the determination of unknowns a strong separation - qualitative analysis of the advantages.
