decylic acid
Very LowTechnical/Scientific
Definition
Meaning
A saturated fatty acid with ten carbon atoms, also known as decanoic acid.
A medium-chain fatty acid found naturally in coconut oil, palm kernel oil, and the milk of some mammals, used in the production of esters for perfumes and flavorings, and as an intermediate in chemical synthesis.
Linguistics
Semantic Notes
The term is almost exclusively used in chemistry, biochemistry, and related industrial contexts. 'Decanoic acid' is the more systematic IUPAC name and is often preferred in modern scientific literature.

Memory Aids
Mnemonic
Think 'DEC-yl-ic' – it has a DECade (ten) of carbon atoms in its chain.
Conceptual Metaphor
A chemical building block; a molecular component with specific properties.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'дециловый спирт' (decyl alcohol). The acid is 'дециловая кислота' or, more commonly, 'каприновая кислота'.
- The English 'decylic' relates to the alkyl group 'decyl', not directly to the number ten, though it is the C10 acid.
Common Mistakes
- Misspelling as 'decyclic acid' (which would imply a cyclic structure it does not have).
- Confusing it with similar-sounding acids like 'decanoic' (same) or 'dodecylic' (C12).

FAQ
Frequently Asked Questions
Yes, decylic acid and decanoic acid are two names for the same chemical compound (C10H20O2). 'Decanoic acid' is the systematic IUPAC name.
It occurs naturally in coconut oil, palm kernel oil, and the milk of some mammals, including goats and cows.
It is used in the manufacture of esters for perfumes and fruit flavorings, as a intermediate in chemical synthesis, and has applications in antimicrobial formulations.
The name 'capric acid' comes from the Latin 'caper' meaning goat, as it was first isolated from goat fat.
