Properties
Colorless liquid; pungent, mustard-like odor.
Flammable, poisonous. Keep tightly closed. d420 0.8540. bp 96-97°. mp 50°. nD20 1.41345. Absorption spectrum: Lüthy, Z. Phys. Chem. 107, 289 (1923).
Flash pt 70°F (open cup); 75°F (closed cup); autoignition
temp 713°F. 72.3% of
the alcohol with 27.7% water forms a constant boiling mixture, bp at 87.5°. Miscible
with water, alcohol, chloroform, ether, petr ether. Upon storage
for several years allyl alcohol polymerizes and a thick syrup is formed
(insol in water, sol in chloroform) which on treatment with ether
yields a brittle resinoid mass: Blicke, J.
