triethyln.

/trʌɪˈɛθɪl/

Etymology: < tri- comb. form 3 + ethyl n.

Chemistry.

(a) A formative denoting the presence of three ethyl groups, C₂H₅, in a compound, as ˌtriethylˈbismuthine n. Bi(C₂H₅)₃, triethyl phosphine n. P(C₂H₅)₃; see also triethylamine n. at Derivatives below. (b) spec. denoting the substitution of three ethyl groups for three hydrogen atoms in the substance designated by the rest of the name; e.g. ˌtriethylˈbenzene n. C₆H₃(C₂H₅)₃, in which three ethyl groups take the place of three H atoms in benzene, C₆H₆. ˌtriethylˈmethane n. CH(C₂H₅)₃ from methane, CH₄. ˌtriethylˈcarbinol n. C(C₂H₅)₃OH. ˌtriethylˈurea n. CONH(C₂H₅)N(C₂H₅)₂. Also used attributively, as triethyl phosphate, (C₂H₅)₃PO₄.
