Properties and Preparation of Nitrobenzene

6 Liquid Nitro Aromatic Compounds 4.6.1 Properties and Preparation of Nitrobenzene 

Nitrobene is also known as secret spot oil, almond oil. 

Nitrobenzene is pale yellow liquid with a bitter almond flavor. It is insoluble in water with a density larger than water, and soluble in alcohol, ether, benzene and oil. In the case of fire, it will be burnt and explode after the heat at high temperature, and can reacts violently with nitric acid. The relative density is 1.205 (15 °C) with melting point of 5.7 °C, boiling point of 210.9 °C, flash point of 87.78 °C, ignition point of 482.22 °C, vapor density of 4.25 and vapor pressure of 0.13 kPa (1 mmHg, 44.4 °C). 

LD50 489 mg/kg (rat oral) 2,100 mg/kg (rat skin) 150 mg/kg (the minimum lethal dose of dog intravenous) 200 mg/kg person (the minimum toxic dose of female oral, hematologic toxicity) 5 mg/kg, (the minimum toxic dose for unpleasantness, human oral). It has mutagenic and reproductive toxicity. 

Nitrobenzene should be sealed and stored in a cool dark environment, while far
