butanone
LowTechnical/Scientific
Definition
Meaning
A colorless, flammable liquid ketone with the chemical formula C₄H₈O, used as a solvent in various industrial applications.
A common industrial solvent and chemical intermediate, also known as methyl ethyl ketone (MEK), valued for its effectiveness in dissolving resins, paints, and varnishes, and its role in manufacturing plastics, textiles, and other synthetic materials.
Linguistics
Semantic Notes
Primarily refers to the specific chemical compound methyl ethyl ketone. The term is almost exclusively used in chemistry, manufacturing, and industrial contexts. It is not a common word in general English.
Dialectal Variation
British vs American Usage
Differences
The compound is referred to as 'butanone' in formal chemical contexts in both varieties. The term 'methyl ethyl ketone' or the abbreviation 'MEK' is more common in industrial and trade settings in both regions, with no significant variation.
Connotations
No differential connotations between UK and US English. The word carries purely technical, chemical, and industrial associations.
Frequency
Extremely low frequency in everyday language in both regions. Usage is confined to specific professional and academic fields.

Usage
Context Usage
Business
Used in procurement, safety data sheets (SDS), and supply chain discussions within chemical manufacturing and industrial cleaning sectors.
Academic
Common in organic chemistry textbooks, research papers on solvent properties, polymer science, and chemical engineering.
Everyday
Virtually never used in everyday conversation. Might be encountered on warning labels for products like adhesives or paint strippers.
Technical
The primary domain. Used in laboratory procedures, industrial formulation, paint and coating specifications, and safety protocols for handling flammable solvents.
Examples
By CEFR Level
- This label says 'butanone'. It must be a chemical.
- The worker wore gloves when handling butanone.
- Butanone is a common solvent found in many paint removers and adhesives.
- The reaction mixture was extracted with butanone, and the organic layer was dried over anhydrous magnesium sulphate.
Learning
Memory Aids
Mnemonic
BUTANONE: BUTAN (like butane, a 4-carbon chain) + ONE (a ketone, containing a carbonyl group C=O). Think: 'A four-carbon ketone'.
Conceptual Metaphor
CLEANING AGENT / DISSOLVER (Butanone is conceptualized as a powerful agent that breaks down and removes other substances).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'бутан' (butane), which is a different hydrocarbon gas.
- The standard Russian term is 'бутанон' or 'метилэтилкетон' (MEK).
- Avoid translating it descriptively as 'масло' or 'жидкость'; it is a specific chemical name.
Common Mistakes
- Mispronouncing it as /bʌˈtænəʊn/ (like 'butter' + 'known').
- Confusing it with 'butane' or 'butanol'.
- Using it in non-technical contexts where 'solvent', 'cleaner', or 'thinner' would be appropriate.
- Incorrect pluralisation ('butanones') is rare as it is typically a mass noun.

FAQ
Frequently Asked Questions
Yes, butanone is flammable and its vapours can be irritating to the eyes, skin, and respiratory system. It must be used with proper safety precautions, including ventilation and protective equipment.
Its primary use is as an industrial solvent for resins, paints, varnishes, and adhesives. It is also used in the production of plastics, textiles, and other chemicals.
The name indicates it is a ketone (the '-one' suffix) derived from butane, meaning it has a four-carbon chain with a carbonyl (C=O) group on the second carbon (hence '2-butanone').
It is not recommended for casual home use due to its flammability and health hazards. It is a powerful industrial chemical. Safer alternatives like acetone or specific commercial paint strippers are available for domestic tasks.
