FIELD: chemistry.
SUBSTANCE: invention relates to chemistry and can be used in coke-chemical production when processing coke gas. The method involves using fractions of heavy crude pyridine bases which form during coal carbonisation as raw material, from which pyridine bases are extracted first and the obtained faction of crude quinoline bases is split into components. The fractions of crude quinoline bases are split into components through supercritical preparative chromatography, where the separated mixture is brought into contact with gas in supercritical state, which is simultaneously the mobile phase and adsorbent.
EFFECT: simpler, faster and more reliable separation.
