    1. Extract residues (coal), creosote oil acid; Wash Oil Extract Residue;
    2. Extract residues (coal), creosote oil acid; Wash oil extract residue
    3. Wash the sample three times with 30 ml hydrochloric acid (3.6).
    4. Rinse the round-bottomed flask with 20 ml of hydrochlorid acid (3.17) and use this to wash the resin column.
    5. extract residues (coal), creosote oil acid, wash oil extract residue, if it contains > 0,005 % w/w benzo[a]pyrene
    6. Wash the combined acid extracts by swirling for approximately 10 seconds with 10 ml of ethyl acetate (3.4).
    7. Run out the excess acid to just above the resin surface and wash the column with water until the effluent is neutral to litmus.
    8. Wash the beaker and filter with 5 ml of hot 6 mol/litre hydrochloric acid (3.2) and twice with boiling water.
    9. [The extract from coal tar oil alkaline extract residue produced by an acidic wash such as aqueous sulfuric acid after distillation to remove naphthalene.

    11. Filter the warm solution through an ash-free filter paper and wash the residue with warm water until the acid reaction is no longer visible.

    15. (The extract oil boiling in the range of approximately 220 to 265 °C from coal tar alkaline extract residue produced by an acidic wash such as aqueous sulfuric acid after distillation to remove tar bases.
