Dynamite, Its Explosive Properties and its Uses

There are many explosive compound in this modern world.Commonly we see that nitrogen containing chemical are explosive in naure.The nitroglycerine is the most explosive .The TNT (Trinitro toluene) is also a common explosive compound.



Dynamite is another much explosive invention invented by Alfred  Nobel during the second world war.Dynamite is a high explosive, which means its power comes from detonation rather than deflagration. Dynamite is mainly used in the mining, quarrying, construction, and demolition industries, and it has had some historical usage in warfare. However the unstable nature of nitroglycerin, especially if subjected to freezing, has rendered it obsolete for military uses. Public familiarity with dynamite led to metaphoric uses, such as saying that a particular issue "is political dynamite.invention: in England on 7 May 1867 and in Sweden on 19 October 1867. Alfred Nobel  originally sold dynamite as "Nobel's Blasting Powder". After its introduction, dynamite rapidly gained wide-scale use as a safe alternative to gunpowder and nitroglycerin. Nobel tightly controlled the patents, and unlicensed duplicating companies were quickly shut down. However, a few American businessmen got around the patent by using a slightly different formulas.

Dynamite was manufactured by the E. I du Pont de Nemours Company until the mid-1970s. Other American dynamite makers of that time period included the Hercules Corporation, Atlas, Trojan-US Powder, Austin, and several other smaller firms. Dynamite has been mostly phased out in favor of water gel explosives, which are cheaper to manufacture, and in many ways safer to handle.

In the United States, in
1885, the chemist Russell S. Penniman invented "ammonium dynamite", a form of explosive that used ammonium nitrate as a substitute for the more costly nitroglycerin. These dynamites were marketed with the trade name "Extra". Ammonium nitrate contains 85% of the chemical energy of nitroglycerin.
