CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Tnt, wetted with not less than 30% water appears as a slurry of a yellow water-insoluble crystalline solid. Can burn, although difficult to ignite. When water has been driven off or evaporated the residue is easily ignited, burns vigorously, and is highly explosive. Produces toxic oxides of nitrogen during combustion. May explode under exposure to intense heat. Primary hazard is blast of an explosion, not flying projectiles or fragments. |

PRODUCT INTRODUCTION
description
2,4,6-Trinitrotoluene is a yellow, odorless solid that does not occur naturally in the environment. It is commonly known as TNT and is an explosive used in military shells, bombs, and grenades, in industrial uses, and in underwater blasting. 2,4,6-Trinitrotoluene production in the United States occurs solely at military arsenals.
