carbon disulfide
A colorless, highly refractive liquid (CS2). It is
prepared by heating sulfur and wood charcoal, or
by reacting methane with sulfur vapor over a
catalyst. It is used in the manufacture of carbon
tetrachloride, and for fumigating books. Its
customary disagreeable odor results from the
presence of small amounts of other sulfur
compounds. Carbon disulfide is both toxic and
flammable.
