Description

General description

Terpinolene is a biogenically emitted monoterpene. Kinetics of gas phase reaction of OH and NO₃ radicals with terpinolene has been investigated. Biotransformation of terpinolene byAspergillus niger and several related species has been reported. Epoxidation of terpinolene in anhydrous conditions using alumina as a heterogeneous catalyst and hydrogen peroxide as the oxidant agent has been studied. It is an major component of essential oil extracted from the aerial parts of Clausena indica.
