1,4-dinitrobenzene usage and synthesis |
chemical properties |
light yellow powder |
general description |
colorless to yellow solid. sinks and mixes slowly with water. |
air & water reactions |
slowly mixes with water. |
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 [urbanski, 1967, vol. 3, p. 290]. if heat and reaction conditions of the nitration are not controlled, detonation comparable to tnt may occur [anon., j. r. inst. chem., 1960, 84, p. 451]. mixture of 1,3-dinitrobenzene with tetranitromethane was found highly explosive [urbanski, 1964, vol. 1, 592]. 1,2-dinitrobenzene 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 [sax, 9th ed., 1996, p. 1374]. |
health hazard |
inhalation or ingestion: headache, vertigo, nausea, vomiting, diarrhea, fever, rapid weak pulse, decreased blood pressure, cyanosis, exhaustion, hepatomegaly, jaundice, albuminurea, hematuria, visual scotomata, amblyopia and nystagmus. eyes: irritation. skin: stains skin yellow; if skin contact is prolonged, can be absorbed into blood causing same symptoms as for inhalation. |
