摘　　要：本文报道了一种GC/NMR分机联用的新方法。对混合物中含量在0.38mol/L以上的化合物,能得到好的氢谱。用此法鉴定了丙酮氯化产物中两个未知物。本法简便、可靠、费用低和无溶剂干扰。一台NMR波谱仪可与数台GC仪联用。The identification of the two components of chlorinated acetone by off-line technique of gas chromatography/nuclear magnetic resonance (NMR) has been reported. The fractions eluted from column were introduced into NMR tube containing CDCl_3, and ~1HNMR spectra of the components were recorded directly, It was not difficult to determine components of chlorinated acetone when the concentration of components was over 0.38mol/L. Advantage of this method is no interference of solvent.
