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.
