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. |
