本文观察了吸附在四种孔结构活性炭中苯,环已烷和正已烷的~1H NMR和笊代苯的~2H NMR谱线在297～195 κ温度范围内的变化。在室温下被吸附的上述各种化合物的~1H NMR及~2H NMR谱均为一条线宽不同的单峰,且随温度下降而增宽。在~2H NMR谱中发现,当以对数表示的谱线半高宽和绝对温度倒数的直线关系上出现拐点时,同时可观察到固体粉末谱线。除2~#活性炭外,最初出现固体粉末谱的温度大致相同。这暗示粉末谱是毛细管中三维类液体固化的结果。文内就所观察到的现象进行了初步讨论。
In this paper, the changes of ~ 2H NMR spectra of benzene, cyclohexane and n-hexane adsorbed on four kinds of pore structure activated carbons in the temperature range of 297 ~ 195 κ were observed. The ~ 1H NMR and ~ 2H NMR spectra of the various compounds adsorbed at room temperature were a single peak with different line widths and broadened as the temperature decreased. It was found in the ~ 2H NMR spectrum that when the inflection point appears in a straight line in the logarithm of the full width at half maximum of the spectrum and the reciprocal of the absolute temperature, the solid powder spectrum can be observed at the same time. In addition to 2 ~ # activated carbon, the initial solid powder spectrum appears roughly the same temperature. This implies that the powder spectrum is the result of three-dimensional liquid curing in the capillary. The text observed the phenomenon of a preliminary discussion.
