trinitromethane Usage And Synthesis
White crystals. Decomposes above 25C, heat of combustion 746 cal/g. Soluble in water.
Manufacture of propellants and explosives.
Explodes on heating, concentrations above 50% in air may explode.
Poison by ingestion and intraperitoneal routes. Moderately toxic by inhalation. Irritating to skin, eyes, and mucous membranes. Inhalation can cause headache and nausea. Causes mild narcosis. A very dangerous explosion hazard; explodes when heated rapidly. Dissolution is exothermic and solutions of more than 50% can explode. mxtures of 90% trinitromethane + 10% isopropyl alcohol in polyethylene bottles have exploded. Frozen mixtures with 2-propanol(lO%) explode when thawed. Can explode during distillation. Mixtures with divinyl ketone can explode at 4℃. When heated to decomposition it emits toxic fumes of NOx.
