What does benzole mean?
Benzole is an alternative, historically British name for benzene, the simplest aromatic hydrocarbon, C₆H₆ — a colourless, highly flammable liquid with a distinctive sweet smell. The term arose in the nineteenth century, when benzene was extracted industrially from coal tar produced by town gasworks, and it came to denote both the pure compound and the crude commercial mixture containing benzene alongside toluene and xylene. This 'motor benzole' served as a common vehicle fuel and solvent in Britain well into the twentieth century, before petroleum-derived supplies displaced coal-tar chemistry. In modern scientific writing the word has been almost entirely supplanted by 'benzene', so 'benzole' survives chiefly in historical, archival, and industrial contexts. Its story captures an era when the nation's fuel, dyes, and pharmaceuticals all flowed indirectly from the humble gasworks retort.
nounAn alternative name for benzene, a colourless aromatic hydrocarbon of formula C₆H₆ obtained chiefly from coal tar; the spelling 'benzole' was formerly standard in British commercial and industrial usage.
- The pure hydrocarbon C₆H₆ (now usually called benzene), a colourless flammable liquid with a characteristic sweet odour.
- A commercial mixture rich in benzene, with toluene and xylene, distilled from coal tar and formerly used as motor fuel and solvent (as in 'motor benzole').
"The gasworks recovered crude benzole as a valuable by-product of coal carbonisation."
"Crude benzole was washed and fractionally distilled to yield pure benzene for the dye industry."
"In the 1920s many British motorists ran their engines on motor benzole blended with petrol."
Rarely pluralised; when it occurs, the plural refers to different commercial grades or fractions of benzole.
"The refinery marketed several benzoles of differing purity."
Before petrochemical plants existed, Britain's petrol stations and its perfumery alike were fed by 'benzole' — a liquid wrung out of coal tar at the local gasworks.

Etymology of benzole
The word derives from 'benzoin', a fragrant balsamic resin imported from Southeast Asia whose Arabic-derived name (ultimately via Late Latin benzoë) gave rise to 'benzoic' acid, first isolated from that resin. When the hydrocarbon was later obtained from coal tar, chemists formed 'benzole' (and the variant 'benzol') on the same stem with the chemical suffix '-ole'. German usage settled on 'Benzol' while British commerce favoured 'benzole'; the internationally standardised form 'benzene' eventually prevailed in both languages.
How benzole is actually used
'Benzole' is now largely historical or technical, encountered mainly in older industrial literature and in accounts of the coal-gas era; chemists today write 'benzene'. It carries no figurative use and should be treated as a specialist term.
Easily confused with benzole
Both names refer to the same compound C₆H₆; 'benzole' is the older, chiefly British commercial term, while 'benzene' is the modern international scientific name.
'Benzol' with one 'e' is essentially the same word in another historical spelling, used particularly for the commercial mixture of benzene with toluene and xylene.
