Carbon Bisulphide

This heavy, oily but volatile liquid readily gives off vapour at ordinary temperatures. It is poisonous, and the same care in manipulating it must be taken as that insisted upon in the case of ether. The smell of the ordinary commercial bisulphide is most offensive, but it is now possible to purchase a specially purified sort from which a particularly disagreeable sulphur-compound of nauseous odour has been removed. Carbon bisulphide, CS₂, sinks in water: it is a powerful solvent for many resins, and mixes perfectly with the fixed and essential oils in all proportions.
