propynen.

Brit.

/ˈprəʊpʌɪn/, U.S.

/ˈproʊˌpaɪn/

Forms: 1800s– propine (now nonstandard), 1900s– propyne.

Origin: Formed within English, by derivation; modelled on a German lexical item. Etymons: propyl n., -ine suffix⁵, -yne suffix.

Etymology: < prop- (in propyl n.) + -ine suffix⁵, after German Propin (A. W. Hofmann 1866, in Monatsbericht der Königl. Preuss. Akad. der Wissensch. zu Berlin, 1865 653). In later use showing alteration of the ending after -yne suffix.

Chemistry.

A gaseous alkyne used in chemical synthesis and for welding (as a component of Mapp gas). Also called allylene, methylacetylene.Formula: CH₃C≡CH.

1877 H. Watts Fownes's Man. Chem. (ed. 12) II. 63 Allylene or propine C₃H₄..is produced by the action of sodium ethylate on bromopropene.

1926 Industr. & Engin. Chem. 18 320/2 For the acetylene series the ending -yne is proposed as a substitute for -ine... Thus we have ethyne, propyne, butyne, butadiyne, etc.

1933 Jrnl. Amer. Chem. Soc. 55 3794 The purified propine was passed into a solution of three moles of ethylmagnesium bromide in ether.

1975 C. D. Gutsche & D. J. Pasto Fund. Org. Chem. viii. 208 Treatment of propyne with water (in the presence of mercuric ion..) yields 2-propenol, which immediately rearranges to..acetone.
