  • Chemical Properties
    • yellow liquid

  • General Description
    • A pale yellow to dark brown liquid. Flash point 190°F. Very slightly soluble in water. Toxic by inhalation and by skin absorption. Combustion give toxic oxides of nitrogen. Density 10.0 lb /gal.

  • Air & Water Reactions
    • Very slightly soluble in water.

  • Reactivity Profile

    Aluminum chloride added to Nitrobenzene containing about 5% phenol caused a violent explosion [Chem. Eng. News 31:4915. 1953]. Heating a mixture of Nitrobenzene, flake sodium hydroxide and a little water led to an explosion, discussed in [Bretherick's 5th ed. 1995]. Mixed with oxidants, i.e. dinitrogen tetraoxide, fluorodinitromethane, nitric acid, peroxodisulfuric acid, sodium chlorate, tetranitromethane, uranium perchlorate, etc., forms highly sensitive explosive, [Bretherick 5th ed, 1995]. Heated mixtures of Nitrobenzene and tin(IV) chloride produce exothermic decomposition with gas production [Bretherick, 5th Ed., 1995].

  • Health Hazard

    Can cause death due to respiratory failure. Classified as extremely toxic. The mean lethal oral dose is probably between 1 and 5 grams. Systemic effects may be delayed for a few hours. Nitrobenzene is rapidly absorbed through the skin. It is a powerful methemoglobin former. Ethyl alcohol aggravates intoxication caused by Nitrobenzene exposure.

  • Fire Hazard

    Moderate explosion hazard when exposed to heat or flame. Reacts violently with nitric acid, aluminum trichloride plus phenol, aniline plus glycerine, silver perchlorate and nitrogen tetroxide. Avoid aluminum trichloride; aniline; gycerol; sulfuric acid; oxidants; phosphorus pentachloride; potassium; potassium hydroxide. Avoid sunlight, physical damage to container, freezing, and intense heat.
