Storage conditions
Storage precautions Store in a cool, ventilated warehouse. Keep away from tinder, warmness sources. Keep the container tightly sealed. It ought to be saved one by one from oxidants, decreasing agents, alkalis, and fit for human consumption chemicals, and combined storage need to be avoided. Equipped with furnace battle gear of corresponding sorts and quantities. Storage areas have to be outfitted with emergency therapy tools for leakage and appropriate containment materials.

stability
1. Chemical properties: fantastically steady to acids and alkalis. It can volatilize with water vapor and has vulnerable oxidation. Iron, zinc and different metals react with hydrochloric acid, or use nickel, copper, silver, etc. as catalysts, stress for reduction, to generate aniline. React with the blended acid of sulfuric acid and nitric acid to generate dinitrobenzene or trinitrobenzene. Chlorination is carried out in the presence of iodine or magnesium chloride to shape m-clonitrobenzene. The chlorination response is carried out in the presence of ferric chloride, and 2,5-dichloronitrobenzene is fashioned at room temperature. At a hundred °C, 2,3,5,6-tetrachloronitrobenzene is generated. HCB is generated above one hundred °C. The interplay with oleum sulfuric acid ordinarily produces m-nitrobenzenesulfonic acid. It reacts with potassium hydroxide to shape o-nitrophenol and a small quantity of p-nitrophenol. Nitrobenzene can react with Grignard's reagent.
2. Stability Stable
3. Forbidden elements robust oxidants, ammonia, amines, etc
4. Aggregation risks do no longer polymerize
5. Decomposition merchandise nitrogen oxides
