(2E)-hex-2-en-1-ol - Uses and synthesis methods
overview
trans -2-hexenol is a volatile component of tea, which was detected in tea in 1966. Colorless liquid, slightly soluble in water, soluble in organic solvents such as ethanol, boiling point 155 ℃, relative density 0.8498 (16/4 ℃), refractive index 1.4367 (20 ℃), showing strong grass odor. It exists in fresh tea leaves and finished tea. The content of tea leaves in withering stage increases sharply, and then decreases with fermentation and drying.
application
Trans-2-hexenol can be used to synthesize a compound E10, E12-hexadecadienal in the sex pherin of bean wild borer.
content analysis
Gas chromatographic analysis with polar columns as GT-10-4.
Toxicity
GRAS(FEMA).
LD50 3500mg/kg (rat, oral).
use limited
FEMA(mg/kg): soft drink 1.0; Cold drink 0.63; Candy 3.8; Baked food 4.1.
Moderate limit (FDA & sect;172.515,2000).
production method
Catalytic reduction of 3-hexynyl-1-ol by Pd-CaCO3 to obtain a mixture of cis and trans, and then fractionated.
It is obtained by reducing 2,4-hexadienoic acid with metal sodium and ethanol.
