butanol
LowTechnical/Scientific
Definition
Meaning
A volatile, flammable alcohol derived from butane, used as a solvent and in chemical synthesis.
Any of four isomeric alcohols with the formula C4H9OH, with n-butanol being the most commercially significant isomer.
Linguistics
Semantic Notes
Primarily a chemistry/engineering term. Refers to a specific chemical compound; not used in abstract or figurative contexts.

Examples
By Part of Speech
adjective
British English
- The butanol fraction was collected.
- Butanol-based fuels are being researched.
American English
- The butanol concentration was too low.
- Butanol solvents are highly effective.
Examples
By CEFR Level
- Butanol is a type of alcohol used in industry.
- The laboratory uses butanol as a solvent for various reactions.
- Some bacteria can produce butanol through fermentation.
- The economic viability of bio-butanol production depends on advanced fermentation techniques and feedstock costs.
- Separation of butanol from the aqueous fermentation broth remains an energy-intensive challenge.
Learning
Memory Aids
Mnemonic
BUTter + alcohOL. Think of 'butter' for the 'but-' prefix (like butyric acid, found in rancid butter) and '-anol' for alcohol.
Conceptual Metaphor
SOLVENT AS CLEANER (when used as a cleaning agent); FUEL AS POWER SOURCE (when discussed as a biofuel).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct cognate 'бутанол' is correct and used. No false friends.
Common Mistakes
- Confusing butanol (C4) with propanol (C3) or ethanol (C2).
- Mispronouncing as 'byoo-TAN-ol' instead of 'BYOO-tuh-nol'.

Frequently Asked Questions
No, rubbing alcohol is typically isopropanol or ethanol. Butanol is a different, more toxic alcohol with four carbon atoms.
No, butanol is toxic and should never be ingested.
Its main uses are as an industrial solvent, a chemical intermediate in plastics production, and a potential biofuel.
It can be both. It occurs in small amounts in some natural fermentations but is primarily produced industrially from petroleum or via engineered bioprocesses.
