What does benzol mean?
Benzol is a noun referring to an industrial liquid obtained from coal tar, consisting largely of benzene together with related hydrocarbons such as toluene. Produced on a large scale during the heyday of coal-gas manufacture and coke ovens, it served as a solvent for fats, resins, and rubber, and as an ingredient in early motor fuels. In older chemical writing — particularly under German influence — 'benzol' could also denote pure benzene itself, but modern scientific practice reserves that name for the single compound C6H6 and treats benzol as a commercial or historical label. The word carries an industrial, somewhat dated flavor today: it appears chiefly in accounts of nineteenth- and twentieth-century manufacturing, patent literature, and discussions of occupational exposure. Knowing the term helps readers interpret older technical documents accurately, since assuming it always means pure benzene can obscure important distinctions about purity and composition.
nounBenzol is a commercial mixture consisting chiefly of benzene, obtained from coal tar, used especially as an industrial solvent and motor fuel additive. In technical contexts the name also refers simply to benzene itself, though modern usage favors 'benzene' for the pure compound.
- A commercial mixture of hydrocarbons, chiefly benzene, distilled from coal tar and used as a solvent and fuel.
- Benzene itself, especially in older or German-influenced chemical usage.
"The old gasworks stored drums of crude benzol in a shed near the tracks."
"Workers at the coking plant collected crude benzol as a valuable byproduct of coal distillation."
"Early internal-combustion engines in Germany often ran on benzol when petrol was scarce."
Usually treated as a mass noun with no plural; a plural form occasionally appears when distinguishing different grades or commercial mixtures.
"The catalog listed several benzols of varying purity."
Before chemists settled on 'benzene', this coal-tar byproduct was sold by the drum as benzol — and it once helped power early motor cars.

Etymology of benzol
Benzol derives from 'benzoin', the name of an aromatic resin imported into Europe from Southeast Asia, whose root traces back through Arabic lubān jāwī ('Javan frankincense'). German chemists coined 'Benzin' and 'Benzol' in the 1830s after isolating the hydrocarbon from coal tar, with the '-ol' suffix reflecting early uncertainty about whether the substance was an alcohol. English adopted 'benzol' directly from German, while 'benzene' arose as an alternative ending once the compound's true nature was understood.
How benzol is actually used
Largely historical or industrial in register; modern chemistry prefers 'benzene' for the pure compound, and 'benzol' survives mainly in trade and older literature. The term was more common in British and continental European usage than in American chemistry.
Easily confused with benzol
Benzene is the pure aromatic hydrocarbon C6H6, while benzol historically denotes the impure commercial mixture derived from coal tar (though the terms are sometimes used interchangeably in older texts).
