三硝基甲苯(TNT)的生产过程分为三个阶段:用混合酸(硝酸和硫酸)硝化甲苯;除去杂质,提纯TNT;成品干燥与包装。生产室空气环境可能受到TNT的蒸汽与粉尘、甲苯、一硝基甲苯、二硝基甲苯及氮氧化物的污染。卫生调查结果表明,生产工艺过程正常进行时,空气环境未受到甲苯、氮氧化物、一硝基甲苯及二硝基甲苯的污染。当采样、测量装置内液面高度等操作时,设备的密闭性受到破坏则TNT可逸散到 Trinitrotoluene (TNT) production process is divided into three stages: with mixed acids (nitric acid and sulfuric acid) nitrification of toluene; remove impurities, purification TNT; finished drying and packaging. The air in the production room may be contaminated with TNT’s steam and dust, toluene, mononitrotoluene, dinitrotoluene and nitrogen oxides. Health survey results show that the normal production process, the air environment is not toluene, nitrogen oxides, mononitrotoluene and dinitrotoluene pollution. When sampling, measuring the level of liquid in the device and other operations, the sealing of the equipment is damaged TNT can escape to
