Physical properties

Terpinyl acetate is a p-menthane monoterpenoid that naturally found in melanoleuca, elettaria cardamomum. It is a colorless liquid with a bergamot, bergamot odor. Soluble in five or more volumes of 70% alcohol; slightly soluble in water and glycerol. Combustible.

Preparation

Terpinyl acetate was successfully synthesized from (x-terpineol and acetic anhydride in supercritical carbon dioxide (SC-C02) by enzymatic catalysis.By acetylation of a-terpineol or mixed isomeric terpineols (Bedoukian, 1967).

General Description

Α-Terpinyl acetate, a monoterpene ester, is a commercially important fragrance molecule. It can be prepared from α-pinene in the presence of H-beta zeolite catalysts. The essential oils obtained from Stachys setifera ssp. iranica, Chamaecyparis obtuse leaves and Thymus willkomii contain Α-terpinyl acetate as one of the main components.

Flammability and Explosibility
