Brief Overview
Alpha-Terpinyl acetate is a natural product found in Xylopia sericea, Elettaria cardamomum, and other organisms with data available. LOTUS - the natural products occurrence database. Terpinyl acetate is a metabolite found in or produced by Saccharomyces cerevisiae.
Manufacturing Process
Natural sources:
Terpinyl acetate can be extracted from essential oils such as pine oil, cardamom oil and cajuput oil. The essential oils are recovered through the physical separation process of partial pressure steam distillation, where steam is passed through plant material to separate the essential oil. Further distillation of the essential oil extracts terpininyl acetate from other components in the oil.
Chemical Synthesis:
A more common manufacturing process for terpinyl acetate is synthesis from alpha-terpineol and acetate anhydride. Catalyst such as concentrated sulphuric acid can be used to drive the reaction. Biocatalysts such as lipases have also be used in place of acids to reduce waste water discharge and equipment corrosion.
