Description and Uses

Dipentene (Limonene) is a monoterpene olefin having potential applications in polymer and fuel chemistry. It is also widely used as flavoring and fragrance agent. Dipentene (limonene) is a promising green solvent. Kinetics of the reactions of limonene with OH and OD radicals has been investigated in a low pressure flow tube reactor coupled with a quadrupole mass spectrometer.
