Trinitrotoluene, also known as TNT, was invented by TJ Wilberland in a failed experiment TNT, 1863, but it was thought to be invented by Nobel for many years, which caused great misunderstanding. Trinitrotoluene is a powerful and quite safe explosive, which will not burn and detonate even if it is punctured by bullets.
At the beginning of the 20th century, it was widely used to fill all kinds of ammunition and explosion, and gradually replaced picric acid. Before the end of World War II, TNT was always the best explosive with comprehensive performance, and was called "the king of explosives".

The energy of TNT:
Each kilogram of TNT explosive can generate 4.2 million joules of energy. It is worth noting that TNT releases less energy than fat (38MJ/kg) and sugar trinitrotoluene (17MJ/kg), but it releases energy very quickly, because it contains oxygen that can be used as an accelerant and does not need oxygen in the atmosphere.
At present, the research on explosion and energy release is often based on "thousand tons of TNT explosives" or "tons of TNT explosives" to compare the energy of large-scale reactions such as explosion, earthquake and planetary impact.
People's Daily Online-Astronomers observed that meteorites hit the moon? The power is comparable to 15 ton TNT explosive.
