1-Octyne Chemical Properties,Usage,Production
Odor
1-Octyne's volatility puts it into a class of "lifting" materials, but its odor type is not exactly desirable. It is ethereal and sweet, of very poor tenacity, warm and remotely resembling the odor of Myrcene in its warm spiciness.
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.
Synthesis
The two synthesis methods of 1-Octyne: 1) from Methyl hexyl ketone and Phosphorous pentachloride followed by hydrolysis and treatment with Sodamide. 2)by Bromination of n-Octene (commercially available) followed by debromination of the Dibromo octane with dry Potassium hydroxide in mineral oil.
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.]
