	Ascanio Sobrero - Wikipedia, the free encyclopedia
		Ascanio Sobrero (1812-1888) was an Italian chemist who discovered nitroglycerin in 1847 while working under Théophile-Jules Pelouze at the University of Torino, who had worked with the explosive material guncotton.
		He initially called his discovery "pyroglycerin", and warned vigourously against its use in his private letters and in a journal article, stating that it was extremely dangerous and impossible to handle.
		Although Nobel always acknowledged and honored Sobrero as the man who had discovered nitroglycerin, Sobrero was dismayed both by the uses to which the explosive had been put, and by the fame and fortune accorded to Nobel because of it.

		Sobrero worked as an assistant to professor Pelouse in Paris and then became professor of chemistry in Torino, Italy.
		Sobrero is quoted to have said "When I think of all the victims killed during nitroglycerine explosions, and the terrible havoc that has been wreaked, which in all probability will continue to occur in the future, I am almost ashamed to admit to be its discoverer".
		Alfred Nobel openly cited Sobrero as the inventor of nitroglycerine.

	Nitroglycerin History Summary (Site not responding. Last check: 2007-09-07)
		Sobrero, guided by scientific curiosity rather than military interests, found that by combining a commonly used skin lotion, glycerol, with nitric acid and sulfuric acid, a colorless, oily liquid of enormous power resulted.
		Sobrero's substance also found use as a key ingredient in two smokeless powders, ballistic and cordite, from which all modern bullets derive their construction.
		Lastly, and perhaps most reassuring to the memory of both Sobrero and Nobel, nitroglycerin, in minute quantities, is regularly relied upon by doctors for the treatment of heart disease.

		Throughout the (The decade from 1860 to 1869) 1860s Nobel received several patents around the world for mixtures, devices and manufacturing methods based on the explosive power of nitroglycerin, eventually leading to the invention of (An explosive containing nitrate sensitized with nitroglycerin absorbed on wood pulp) dynamite.
		Although Nobel always acknowledged and honored Sobero as the man who had discovered nitroglycerin, Sobrero was dismayed both by the uses to which the terrible power of the explosive had been put, and by the fame and fortune accorded to Nobel because of it.

		It is mixed with an absorbent material to form dynamite (which is not so sensitive to slight shocks) and is also used as a component of smokeless powder.
		Nitroglycerin was discovered (c.1847) by the Italian chemist Ascanio Sobrero and was first produced commercially by Alfred Nobel.
		It is used medicinally to provide temporary relief from the symptoms of angina pectoris; the body converts it to nitric oxide, which causes narrowed blood vessels to relax.

		It was first prepared in 1846 by the Italian chemist Ascanio Sobrero by adding glycerol to a mixture of concentrated nitric and sulfuric acids.
		It is also used with nitrocellulose in some propellants, especially for rockets and missiles, and it is employed as a vasodilator in the easing of cardiac pain.
		Nitroglycerin, the most powerful explosive in common use, was discovered in 1846 by the Italian scientist Ascanio Sobrero.

		Nitroglycerin, also called trinitroglycerin, nitroglycerine and more correctly glyceryl trinitrate is a highly explosive pale yellow viscous liquid, first synthesized by an Italian called Ascanio Sobrero in 1846.
		It is easily prepared by the action of concentrated nitric and sulphuric acids on glycerol.
		Ironically, nitroglycerin has been used for the treatment of heart diseases such as angina since 1879 and is still widely prescribed today.

	Is Nitroglycerine In This? Page 3
		In 1846, Ascanio (Ascagne) Sobrero, then a pupil of Pelouze, the eminent French chemist, hit upon Nitroglycerin by mixing fuming nitric acid, sulphuric acid, and glycerin in the proper proportions.
		Ascanio didn't know it was loaded, for he subsequently blew the lab to splinters, narrowly escaping death himself.
		In those early years, nitroglycerin had an adverse effect even upon man's basic nature, as McLaurin described life in the oil regions of Pennsylvania, "The Roberts Petroleum Torpedo Co. was organized in New York to construct torpedoes and carry on the business extensively.

		Sobrero Ascanio, a young Italian chemist interested in explosives, invented nitroglycerine in the late 1840s.
		The highly explosive liquid was produced by mixing glycerine with sulfuric and nitric acid and was considered too dangerous to be of any practical use.
		Alfred Nobel, while working in Paris in a private laboratory, met Ascanio and became very interested in the commercial application of nitroglycerine.

		Nitroglycerin is an explosive compound formed by the combination of glycerol and nitric and sulfuric acids.
		It was first synthesized in 1864 by chemist Ascanio Sobrero, who destroyed his notes for fear of the damage his highly unstable discovery might cause.
		But word got out, and the volatile compound came into use even before 1867, when Alfred Nobel combined nitroglycerin with an absorbent clay to create dynamite, which substantially reduced the dangers of the compound in its purest form.
