cycloaliphatic
C2 / Very LowHighly Technical (Chemistry)
Definition
Meaning
Relating to or being an organic compound whose carbon atoms form a ring, but which is not aromatic.
In organic chemistry, describes saturated or unsaturated hydrocarbon compounds containing a ring structure without the delocalized electron system characteristic of aromatic compounds. These compounds are a subclass of aliphatic compounds.
Linguistics
Semantic Notes
This is a compound term from 'cyclo-' (ring) + 'aliphatic' (non-aromatic hydrocarbons). It specifically excludes benzene-like aromaticity. Often used interchangeably with 'alicyclic', though some technical contexts make subtle distinctions.
Dialectal Variation
British vs American Usage
Differences
No significant spelling or usage differences. The term is identically used in both British and American technical chemistry.
Connotations
Purely technical, with no cultural or regional connotations.
Frequency
Extremely rare outside specialized chemistry literature and industrial contexts in both regions.

Business
Rare. Might appear in patents, technical data sheets for specialty chemicals, or materials science R&D reports.
Academic
Exclusively in advanced organic chemistry, polymer science, and materials engineering textbooks and research papers.
Everyday
Virtually never used.
Technical
Core term in organic chemistry for classifying hydrocarbon structures; common in polymer chemistry (e.g., cycloaliphatic epoxy resins).
Examples
By Part of Speech
adjective
British English
- The synthesis yielded a novel cycloaliphatic compound with high thermal stability.
- Cycloaliphatic epoxy resins are favoured in UV-curable coatings.

Learning
Memory Aids
Mnemonic
Think 'CYCLE' (a ring) + 'aliphatic' (fatty, non-aromatic chain). It's a fatty chain that closed into a ring.
Conceptual Metaphor
A closed loop of a non-special (non-aromatic) chain, like a necklace made of ordinary rope rather than special beaded wire.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct calque 'циклоалифатический' is correct but highly technical. Mistaking it for 'ароматический' (aromatic) is a key conceptual error.
Common Mistakes
- Confusing with 'aromatic'.
- Using it to describe any ring-shaped molecule.
- Misspelling as 'cycloalphatic' or 'cyclo-aliphatic'.
- Incorrect stress placement.

Frequently Asked Questions
No, they are opposites in key aspects. Aromatic compounds have a special, stable ring of electrons (like benzene). Cycloaliphatic compounds have ring structures but lack this electron delocalization.
Almost exclusively in advanced textbooks, research papers, and technical documentation within organic chemistry, polymer science, and the specialty chemicals industry.
Cyclohexane is a classic example—a saturated six-carbon ring that is not aromatic.
In most general chemistry contexts, yes. 'Alicyclic' is slightly more common in broader usage, while 'cycloaliphatic' might emphasize the 'aliphatic' (non-aromatic) nature more specifically.
