這好像不太可能吧!還要加熱、加硫酸,那產生的三硝基甲苯不就立刻爆炸了!有沒有搞錯啊!

CH3 CH3 │ O2N │ NO2 ╱╲ H2SO4 ╲╱╲╱│○│+3HONO2 ───→ │○│ +3H2O ╲╱ Δ ╲╱ │ NO2(甲苯) (TNT,三硝基甲苯)以甲苯為原料,加入濃硝酸,以濃硫酸為催化劑,混合加熱可以產生三硝基甲苯。硝基(─NO2)會取代於苯環上。

狂人是對的 請小嵐老師自己找找答案HistoryTNT was first made in 1863 by a German chemist Joseph Wilbrand, but its potential was not seen for several years, mainly because it was so hard to detonate and because it was less powerful than other explosives. Amongst its advantages, however, are that it can be safely melted using steam or hot water and so poured molten into shell cases. It is also so insensitive that, for example, in 1910 it was exempted from the British 1875 Explosives Act from actually being considered as an explosive for the purposes of manufacture and storage.The German armed forces adopted it as an artillery shell filling in 1902, and the British gradually started using it as replacement for lyddite in 1907. [edit]PreparationThe synthesis is done in a stepwise procedure. First toluene is nitrated with a mixture of sulfuric and nitric acid. Even lower concentrated acid mixtures are capable of doing the first and second introduction of a nitrogroup. The nitrogroups decrease the reactivity of the toluene drastically, because they are electron withdrawing groups. After separation the mono- and dinitrotoluene is fully nitrated with a mixture of nitric acid and oleum (sulfuric acid with up to 60% dissolved SO3), this mixture is far more reactive and is capable of introducing the last nitrogroup. The waste acid from this process is used for the first step of the reaction in industrial synthesis.http://en.wikipedia.org/wiki/Trinitrotoluene
