摘要：

An extrographic procedure for compound-class fractionation of coal-derived liquids and related materials is presented. The fractionation column consists of one extrographic separation section (silica gel) and two filter sections (silica gel and basic alumina). The fractions obtained are: saturates, aromatics free of nitrogen, neutral heterocompounds with pyrrolic nitrogen, monohydric phenols, dihydric phenols, and highly polar compounds. From preliminary analyses it can be predicted that the fractionation selectivity of extrography is very close to that of chromatography. © 1990.
