3,7-Dimethyl-2,6-octadienenitrile Usage And Synthesis

Aroma

Penetrating and powerful, oily-green, lemony-fresh odor with some resemblance to that of Citral, but overall harsher, not as sweet and not as natural in its notes. Powerful lemony, but also somewhat "metallic" and not expressly sweet taste - in dilutions below 5 ppm. It should be noted that this material has a poorer effect in rncidified aqueous medium than the effect obtained with Citral under similar conditions.

Chemical Properties

Almost colorless or very pale yellowish oily liquid. B.P. 222°C. Sp.Gr. 0,87.
Practically insoluble in water, soluble in alcohol and oils.

Occurrence

Has apparently not been reported to occur in nature.

Uses

Geranyl Nitrite, is a substituted terpenoid odorant with a fruity odor quality. It is one of the most potent cyclase stimulators.

Preparation

From geranialoxime with acetic anhydride (Arctander. 1969).

Production Methods

3,7-Dimethyl-2,6-octadienenitrile can be produced from: 1) Geranialoxime with Acetic anhydride. 2) Geranyl chloride and Sodium cyanide.

Flammability and Explosibility

Non flammable

Metabolism

The toxicity of organic cyanides appears to depend, in almost every case, on whether they can be metabolized in the body to the free cyanide ion, CN~, and on the rate and extent of this conversion and the rate of detoxication of cyanide to thiocyanate. Alkyl cyanides appear to be metabolized in the body chiefly by formation of hydrogen cyanide plus the acid with one less carbon atom (Williams, 1959).
