Form and properties of the medium
Thread Content
I would like to ask everyone: Do nitro-o-xylene, nitroethylbenzene, and nitrotoluene all belong to the category of liquids? What are their boiling points respectively? Are their hazardous properties classified as moderately explosive? If they are liquids, do they fall under the regulations governing hazardous materials?
【Nitro-o-xylene】A colorless liquid that forms needle-shaped crystals at low temperatures. Melting point: 15°C; boiling point: 240°C (245°C) at 131°C (2.66 kPa) and 72°C (0.133 kPa). Relative density: 1.1402 (20/4°C); refractive index: 1.5441; flash point: 107°C. Soluble in ethanol. It can volatilize with water vapor.

Nitroethylbenzene: a pale yellow liquid, toxic. It is soluble in ethanol and ether, soluble in propane and benzene, and insoluble in water. Appearance and properties: Colorless oily liquid. Molecular weight: 151.17. Vapor pressure: 3.06 kPa at 135°C. Flash point: 112°C. Melting point: -32°C. Boiling point: 245–246°C. Solubility: Insoluble in water; soluble in alcohol, ether, and most organic solvents. Density: Relative density (water = 1): 1.12. Stability: Stable. Hazard symbol: 14 (Toxic substance)
Nitrotoluene: It is a colorless or pale yellow crystal with a melting point of 354 K (80.9°C). It is explosive and one of the commonly used **components. Refined trinitrotoluene is very stable. Unlike nitroglycerin, it is not sensitive to friction, vibration, etc. It is not easy to explode even if it is shot at. Therefore, it requires *pipe startup. It also does not react chemically with metals or absorb moisture. Therefore, it can be stored for many years. But it reacts vigorously with alkalis to form unstable compounds
Could you please mention the source? Thank you!
Just search on Baidu to find its number.

For volatile liquid media, the gas phase space must be taken into consideration to determine whether they fall under the scope of regulatory requirements
