Properties: Yellow prisms or irregular pieces turning white on cooling. d20 1.14. Opaque at 10°, mp 15°. bp776 51°. The vapors are green and burn with a purple flame. Explosive: Mixtures with air may explode! nD20.5 1.3826. Sol in anhydr solvents. pH of a 40% aq soln: 2.1-2.7; d420 1.27. Polymerizes quickly on standing, on contact with water (violent reaction), or when dissolved in solvents contg water. The anhydr polymer changes to the monomer on heating. Solns of the monomer are obtained on heating the polymer with anethole, phenetole, safrole, methyl nonyl ketone, or benzaldehyde. LD50 in rats, guinea pigs (mg/kg): 2020, 760 orally (Smyth).
