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.] |
