benzene(redirected from coal tar naphtha)
Also found in: Dictionary, Thesaurus, Encyclopedia.
a liquid hydrocarbon, C6H6, obtained mainly as a byproduct of the destructive distillation of coal, used as a solvent. It is irritant, toxic, and carcinogenic.
ben·zene(ben'zēn), Do not confuse this word with benzine.
The basic six-carbon ring structure in most aromatic compounds; a highly toxic hydrocarbon from light coal tar oil; used as a solvent.
[benzoin, + -ene]
benzene/ben·zene/ (ben´zēn) a liquid hydrocarbon, C6H6, from coal tar; used as a solvent. It is toxic by transdermal absorption, ingestion, or inhalation; chronic exposure may cause bone marrow depression and aplasia and leukemia.
benzene hexachloride (BHC) a chlorinated hydrocarbon, C6H6Cl6, having numerous isomers; the gamma isomer is lindane.
A colorless, flammable, toxic, liquid aromatic hydrocarbon, C6H6, derived from petroleum and used in or to manufacture a wide variety of chemical products, including DDT, detergents, insecticides, and motor fuels. Also called benzol.
a colorless, highly flammable liquid hydrocarbon (C6H6) originally derived by fractional distillation of coal tar. It is now derived by catalytic reforming during petroleum refining. The prototypical aromatic compound, it is used in the production of various organic compounds, including pharmaceuticals.
benzeneA volatile, flammable hydrocarbon by-product of destructive coal distillation, which is present in coal tar; it is the simplest aromatic compound. Benzene is an organic solvent, and is both toxic—in particular to mucocutaneous surfaces—and carcinogenic; chronic exposure to benzene is linked to bone marrow depression, aplastic anaemia, and acute myelogenous leukaemia, one-fourth of which are preceded by pancytopenia and/or peripheral neuropathies.
A colorless volatile flammable toxic liquid hydrocarbon used as a solvent and as a motor fuel.
Mentioned in: Myelofibrosis
a liquid hydrocarbon, C6H6, from coal tar; used as a solvent.
a chlorinated hydrocarbon. The gamma isomer was used extensively as an insecticide. Called also Gammexane, lindane.
benzene hexachloride poisoning
the closed hexagon of carbon atoms in benzene, from which the different benzene compounds are derived by replacement of the hydrogen atoms.
