Properties: Long prisms, mp 16°, forming a corrosive liquid. Acrid, repulsive odor. d420 1.0153. bp760 163°; bp30 81°; bp12 63°. nD20 1.43143. Flash pt, open cup: 170°F (76℃). Sol in warm water; miscible with alc, ether. Polymerizes easily, especially on heating or in the presence of traces of HCl. The polymer forms a ceramic-looking mass, sol in abs alc, from which it is precipitated by ether.
