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.
