1-Octyne Chemical Properties,Uses,Production

Chemical Properties

CLEAR COLOURLESS TO YELLOW LIQUID

Uses

1-Octyne is widely used in organic reactions such as halogenation, hydration, oxidative cleavage, hydrogenation, hydrohalogenation, nitrile formation, polymerization and substitution reactions. It is used a precursor for the preparation of monohalogen substituted akenes or dihalogen substituted alkanes on treated with hydrogen halides.

Safety Profile

Mutation data reported. Whenheated to decomposition it emits acrid smoke andirritating vapors.

Purification Methods

Distil I-octyne from NaBH4 to remove peroxides. Fractionate it through a 10inch Widmer column (p 11) at 125-126o/759mm [Sletzinger & Dawson J Org Chem 14 853 1949.] [Beilstein 1 III 1005, 1 IV 1034.]
