p-DINITROBENZENE Production

Reactivity Profile All three isomers have similar properties and may react vigorously with oxidizing materials. Their reaction with nitric acid (nitration) will lead to a mixture of trinitrobenzenes possessing high-explosive properties. If heat and reaction conditions of the nitration are not controlled, detonation comparable to TNT may occur. Mixture of 1,3-dinitrobenzene with tetranitromethane was found highly explosive. 1,2-dinitrobenzene (100-25-4) is a severe explosion hazard when shocked or exposed to heat or flame. When heated to decomposition all dinitrobenzens emit toxic fumes of nitrogen oxides.
