PACKAGING

4-NITROBENZOIC ACID

ICSC: 1684

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE-TO-YELLOW CRYSTALS. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. Chemical dangers Reacts with bases, reducing agents and strong oxidants. Decomposes on heating and on burning. This produces toxic fumes including nitrogen oxides.	Formula: C₇H₅NO₄ / HOOCC₆H₄NO₂ Molecular mass: 167.1 Decomposes at 350°C Melting point: 242°C Density: 1.61 g/cm³ Solubility in water, g/100ml at 25°C: 0.03 (poor) Vapour pressure, Pa at 50°C: 1 Flash point: 201°C c.c. Auto-ignition temperature: 300°C Explosive limits, vol% in air: 1.8-? Octanol/water partition coefficient as log Pow: 1.89

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by ingestion. Effects of short-term exposure The substance is irritating to the eyes, respiratory tract and skin.	Inhalation risk A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered. Effects of long-term or repeated exposure Animal tests show that this substance possibly causes toxicity to human reproduction or development.
