octadecyln.

Brit.

/ˌɒktəˈdɛsʌɪl/,

/ˌɒktəˈdɛsɪl/, U.S.

/ˌɑktəˈdɛsᵻl/

Forms: 1800s– octadecyl, 1800s– octodecyl.

Origin: Formed within English, by compounding. Etymons: octa- comb. form, decyl n.

Etymology: < octa- comb. form + decyl n. Compare slightly earlier octadecane n.With form octodecyl compare octo- comb. form.

Chemistry.

Any of the series of hydrocarbon radicals —C₁₈H₃₇ derived from the octadecanes; spec. the straight-chain radical —CH₂(CH₂)₁₆CH₃ (also called stearyl). Usually attributive or a formative element in chemical names.
