摘要
应用高效液相色谱（ＨＰＬＣ）以正相（ＮＰ）－ＨＰＬＣ配以反冲（ＢＦ）技术，测定了煤焦油中极性化合物的总量。以反相（ＲＦ）－ＨＰＬＣ辅以制备液体色谱研究了极性物段份的制备及典型极性化合物的分析，文中分析的实样由山西省一些焦化厂提供。
The analytical methods of polar
compounts in coal tar have been studied in which high performance liquid
chromatography(HPLC) has been primarily employed. The total amount of polar compounds in
tar has been determined by using normal-phase(N-P) HPLC associated with back-flush(BF). The
study on preparing concentrated fraction of polar compounds and analyzing typical polar
components has been made by using reversed-phase(R-P) HPLC associated with preparation
liquid chromatography. Test samples were provided by some coking plants in Shanxi province.
