摘要：

In order to study fractionation selectivity, chromatography of shale oil on silica gel was used as a reference for comparison with the extrographic fractionation previously described. The overlapping effects between the adjacent fractions were evaluated using i.r., H-1 n.m.r. and mass spectrometry. It was found that extrographic fractionation produced better separation than chromatography. In both cases, subsequent separation of the n-hexane fractions on silica gel/silver nitrate columns into saturates and olefin/monoaromatic fractions was needed.
