L-BORNYL ACETATE Usage And Synthesis

Chemical Properties

Colorless solid; sweet herbaceous aroma.

Chemical Properties

L-Bornyl acetate is a clear colorless liquid or crystalline mass, melting at 29℃. (when pure). (the inactive all-form does not crystallize). Sp.Gr. 0.98. B.P. 226℃. Very slightly soluble in water, almost insoluble in Propylene Glycol and Glycerin, soluble in alcohol and oils. Sweet herbaceous-piney odor with a balsamic undertone, Reminiscent of Pme Needles.

Occurrence

Reported found in carrot, coriander, spike lavender, pine needle, rosemary, sage and valerian root.

Uses

(?)-Bornyl acetate can be used:

• As a key intermediate in the preparation of camphor.
• To prepare (?)-englerin A, an anti-cancer agent.

Uses

Suggested for use in Fougeres, Chypres, Lavender colognes, Room spray fragrances, Bathoils, Pine fragrances, etc. lts odor is richer than that of the iso-Bomyl acetate. Finds some use in flavor compositions for Fruit and Spice flavorings. The concentration will usuallybe about 70-80 ppm in the finished product.

Preparation

By esterification of laevo-Bomeol. On account of its high melting point it can also be isolated from a mixture of isomers. dextro-Bornyl acetate is produced from dextro-Borneol (esterification with Acetic anhydride and Sodium acetate).

Aroma threshold values

Medium strength odor, balsamic type.

General Description

Produced and qualified by HWI pharma services GmbH.
Exact content by quantitative NMR can be found on the certificate.

Flammability and Explosibility

Non flammable
