Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay) and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, and patented in 1867.Dynamite is occasionally used as an initiator or booster for AN and ANFO explosive charges.

2,4,6-trinitrotoluene is better known by its initials, TNT. It is an important explosive, since it can very quickly change from a solid into hot expanding gases. Two moles of solid TNT almost instantly changes to 15 moles of hot gases plus some powdered carbon, which gives a dark sooty appearance to the explosion. This is where another explosive, nitroglycerin, has an advantage, since it produces a smokeless explosion, allowing artillery and naval gunners to fire without their field of vision becoming obscured by smoke during the action.
TNT is made by adding 3 NO2 groups (from nitric acid) to toluene. At low temperatures, the mononitrotoluenes are made, and as the reaction temperature is increased the dinitro compounds are formed, until eventually TNT is formed.
I hope it helps you...
