DECAHYDRO-2-NAPHTHOL Usage And Synthesis

Chemical Properties

white to light yellow weak paste. Mild, sweet, slightly camphoraceous-woody, also warm and mildly spicy odor of fair tenacity. The odor has been compared to that of Dihydrocarveol. Practically insoluble in water, soluble in alcohol and oils.

Uses

This alcohol has been used, and is still used on a modest scale, in perfume compositions, mostly in connection with woody and camphoraceous fragrance types, including the lonones, Cyclohexylderivatives, etc.

Production Methods

Decahydro-2-naphthol is produced by catalytic hydrogenation of befa-Naphthol. The reaction yields a mixture of cis- and tram-isomers, but the perfumers generally prefer the tram-isomer, or a material primarily consisting of that isomer.
