benzene
A colorless, aromatic hydrocarbon (C 6
H 6 ), usually obtained by the
carbonization of coal, or from petroleum fractions
by means of catalytic dehydrogenation. It is used
to remove excess glair or grease from leather
bindings. Although used extensively in the past.
it is seldom used today because of its high
flammability and extremely toxic nature. It is not
to be confused with benzine (also used for the
same purposes), which is a petroleum product
obtained by distillation.
