/ˌproʊpɑrˈdʒɪlɪk/

Origin: A borrowing from German, combined with an English element. Etymons: German Propargyl , -ic suffix.

Etymology: < German Propargyl propargyl n. (the English word is first attested slightly later) + -ic suffix.In propargylic ether n. at Compounds after German Propargyläther (C. Liebermann 1864, in Zeitschr. f. Chem. u. Pharm. 749).

Chemistry.

Of or containing propargyl.Recorded earliest in propargylic ether n. at Compounds.

ΚΠ

1866 H. Watts Dict. Chem. IV. 728 Propargylic ether.—When tribromide of allyl is digested..with alcoholic potash, the alcohol distilled therefrom yields with ammoniacal silver-nitrate a white precipitate..regarded by Liebermann as the silver-salt of an ether to which he gives the name above.

1876 H. E. Armstrong Introd. to Study of Org. Chem. vi. 163 Propargylic alcohol is a colourless mobile liquid.

propargylic ether n. an ether containing a propargyl group; (originally) †ethyl propargyl ether, CH≡CCH₂OCH₂CH₃ (obsolete).
