Literature References: Prepd by heating glycerol with formic acid: O. Kamm, C. S. Marvel, Org. Synth. coll. vol. I, 42 (2nd ed., 1941); cf. Delaby, Dubois, Compt. Rend. 188, 710 (1929). Toxicity study: Smyth, Carpenter, J. Ind. Hyg. Toxicol. 30, 63 (1948).
Properties: Colorless liquid; pungent, mustard-like odor. 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. Keep tightly closed. 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. Am. Chem. Soc. 45, 1563 (1923). LD50 orally in rats: 64 mg/kg (Smyth, Carpenter).
