Properties: Viscous liq. nD20 1.4941. d420 1.554. Viscosity (cSt): 166.8 (40°); 77.8 (50°). Soly in water: 0.705 g/100 ml at 20°; in benzene: 21.40 g/100 ml at 20°. Very sol in ethanol, ether. Forms a cryst hydrate, mp 32°, when washed with water and allowed to stand overnight at 20°; returns to unhydrated form when allowed to stand at 60° for 2 hrs. When used medicinally it is usually diluted with lactose or mannitol to reduce explosive liability, see pentaerythritol tetranitrate.
