decahydronaphthalene
Very low (exclusively technical)Exclusively scientific/technical
Definition
Meaning
A saturated hydrocarbon consisting of two fused cyclohexane rings (C₁₀H₁₈); a colorless liquid used as a solvent.
A specific bicyclic organic compound belonging to the class of decalins, often used as a high-boiling solvent in industrial and laboratory applications for resins, waxes, and other non-polar materials.
Linguistics
Semantic Notes
The term is a precise IUPAC chemical name. It is synonymous with 'decalin', though 'decalin' (specifically referring to the cis- and trans-isomers) is the more common generic name in chemistry. It has no figurative or everyday meanings.
Dialectal Variation
British vs American Usage
Differences
No significant differences in spelling or usage; it is an international scientific term.
Connotations
None beyond its technical chemical definition in both varieties.
Frequency
Equally rare in both British and American English, confined to chemical literature and industry.

Examples
By Part of Speech
verb
British English
- The naphthalene was decahydronaphthalenated under high pressure.
American English
- The process decahydronaphthalenates the aromatic feedstock.
adjective
British English

Learning
Memory Aids
Mnemonic
Think: 'DECA' (ten) + 'HYDRO' (hydrogen, meaning saturated) + 'NAPHTHALENE' (the aromatic starting compound it's derived from). It's the fully hydrogenated version of naphthalene with ten extra hydrogens.
Conceptual Metaphor
N/A. The term is purely denotative with no common metaphorical extensions.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct transliteration 'декагидронафталин' is standard and correct. The main trap is confusing it with 'нафталин' (naphthalene/mothballs), which is a different, aromatic compound.
Common Mistakes
- Misspelling as 'decahydronapthalene' (missing 'h' after 'p').
- Incorrectly pluralizing as 'decahydronaphthalenes' when referring to the substance generically.
- Confusing it with tetralin (tetrahydronaphthalene), which is only partially hydrogenated.

FAQ
Frequently Asked Questions
Like many organic solvents, it can be flammable and irritate the skin and eyes. Always consult its Safety Data Sheet (SDS) for specific hazards and handling instructions.
Naphthalene (C₁₀H₈) is an aromatic compound (has a distinctive smell, used in mothballs). Decahydronaphthalene (C₁₀H₁₈) is its fully hydrogenated, saturated counterpart, with no aromatic character and different chemical properties.
It is sold by chemical suppliers (e.g., Sigma-Aldrich, Fisher Scientific) for laboratory and industrial use, not available to the general public.
Due to its high boiling point, low polarity, and chemical stability, it is useful for reactions requiring high temperatures or for dissolving non-polar organic compounds.
