Introduction to o-nitrotoluene
O-nitrotoluene is an organic compound with the molecular formula C7H7NO2. It has a colorless or slightly yellow oily liquid form and a unique aromatic odor. Its physical properties include: melting point of 5 ° C, boiling point of 216 ° C, density of 1.14 g/cm ³, insoluble in water, but easily soluble in organic solvents such as alcohols, ethers, etc. Under high temperature and pressure conditions, ortho nitrotoluene undergoes decomposition, nitration, and other reactions, producing products such as toluene, nitrogen, and nitric oxide.
chemical property
O-nitrotoluene has high chemical stability, but it undergoes decomposition and nitration reactions under specific conditions. Under acidic conditions, it can generate dinitrates and trinidates of ortho nitrotoluene. Its chemical properties include: melting point -9.5 ° C, boiling point 222 ° C, relative density 1.16, flash point 106 ° C (closed form) 23.
Storage and Handling
Nitrotoluene should be stored in a cool and ventilated warehouse, away from sources of fire and heat. Containers should be sealed and stored separately from oxidants, reducing agents, alkalis, and edible chemicals. The storage area should be equipped with corresponding fire-fighting equipment and emergency response equipment for leaks.
