GAMMA-TERPINENE Usage And Synthesis

Chemical Properties	clear liquid
Chemical Properties	γ-Terpinene is a colorless liquid with an herbaceous citrus odor and can be prepared by isomerization of limonene.
Chemical Properties	p-Mentha-1,4-diene has a characteristic lemon odor (not as lemony as the alpha-isomer, but warmer). It has a slightly bitter, herbaceous, citrus-like flavor; woody, terpene, tropical lemon odor.
Preparation	From geranyl pyrophosphate by migration of a positive-charge, hydrid shift from the isopropyl side chain into the cyclohexenoid ring; from the essential oil of Lantana camara; also from p-cymene by the action of sodium and alcohol in liquid ammonia.
Taste threshold values	Taste characteristics at 40 ppm: terpy, citrus, limelike, oily, green with a tropical fruity nuance.
Safety Profile	Moderately toxic by ingestion. A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
