Molecular Mass：154.25
Properties：
It
has three kinds of optical isomers: Left rotated, Right rotated, and
Non rotated.
The
Left Rotated isomer is the most commonly existing type in the

The
substance is achromatous to primrose liquid, with boiling point at
198℃,
and flash point at 76℃.
It is not resolvable in water, and just very slightly resolvable in
Glycerol. It is resolvable in Ethanol, Propanediol and other Oils.
Producing Metheod：
Synthesized
with Myrcene, α-Pinene

Discrimination:
Take
1mL of the substance，add
1mL Anhydrous Acetic acid and 1 drop of Phosphonic Acid. Keep it
heated for 10min. Add 1mL water and shake the mixture in warm water
for 5min. Add Anhydrous Sodium Carbonate Liquor（1+8） after it cools
down, and adjust the mixture until the liquor becomes slightly
alkaline and the aroma of Linalyl Acetate comes out.
