Usage

Chemical Properties

White crystals. Decomposes above 25C, heat of combustion 746 cal/g. Soluble in water.

Uses

Manufacture of propellants and explosives.

Hazard

Explodes on heating, concentrations above 50% in air may explode.

Safety Profile

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.

THE MECHANISM OF AROMATIC NITRATION BY TETRANITROMETHANE

Aromatic nitrations by tetranitromethane are shown to be photochemically initiated and are believed to proceed via trinitromethyl nitrite.

Synthesis of Neutral and Charged Trinitromethyl Borohydrides and Their Complexes

We propose several simple and effective methods for the synthesis of previously unknown trinitromethyl borohydrides and their complexes with simple cyclic ethers and aromatic nitrogen- containing heterocycles, whereas acyclic ethers did not form such complexes. The data from physicochemical investigations showed that these unique compounds contain directly linked oxidizing and reducing fragments. Some transformations of trinitromethylborane complexes were demonstrated, which can occur by cleavage of all types of bonds formed by boron atom in the starting compounds.
