n-HEXANE,
a colorless liquid with a slightly disagreeable
odor, is the straight-chain alkane with six carbon
atoms. It evaporates very easily into the air and
dissolves and highly flammable It is insoluble in
water and miscible with alcohol, chloroform, and
ether. It is used primarily to produce solvents
when it is mixed with similar chemicals. Common
names for these solvents are commercial hexane,
mixed hexanes, petroleum ether, and petroleum naphtha.
The major use n-hexane is to extract vegetable oils
from crops due to its narrow distillation range
and selective power. Its wide usages are in
the rubber industry as a base for rubber cement
and in tyre manufacture and in contact adhesives,
paints and inks, where fast drying and ability to
suspend are required. Application is
also found in the manufacture of SBR rubber where
hexane is used as a medium in the polymerisation
process.
