Habe in einem alten Buch noch eine Reinigung gefunden. Leider nur in Englisch.
Carbon Bisulfide (b.p. 46.2°). — This common solvent (Friedel
and Crafts reaction) and reagent is extremely inflammable and
it has been known to ignite from being overheated on the steam
bath. For the distillation of appreciable quantities it is advisable
to use a pan of water warmed on the steam bath to just
the required temperature. For the purification of crude carbon
bisulfide Wieland and Bettag11 recommend shaking with mercury,
then with a cold, saturated solution of mercuric chloride followed
by cold, saturated potassium permanganate solution, drying over
phosphorus pentoxide, and distilling the product.
