Nitro-glycerine, with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives used. Nitro-glycerine is extremely sensitive to shock and to rapid heating; it begins to decompose at 50 to 60 °C and explodes at 218 °C. nitro-glycerine has a high freezing point (13 °) and the solid is even more shock-sensitive than the liquid. This disadvantage is overcome by using mixtures of nitro-glycerine with other oxynitrates. A mixture of nitro-glycerine and ethylene glycol dinitrate freezes at −29 °C.
It was first prepared in 1846 by the Italian chemist Ascanio Sobrero (1812–1888), who nitrated glycerol using a mixture of nitric acid and sulfuric acid. Sobrero, who was injured in an explosion doing his research, realized the compound’s danger and abandoned work on nitro-glycerine. Twenty years after Sobrero’s discovery, Alfred Nobel (1833–1896) developed its use commercially.
The explosive power of nitro-glycerine is related to several factors. Each molecule of nitro-glycerine contains three nitrate groups, which serve as oxidizing agents for …show more content…
The main medical use of nitro-glycerine is to treat angina pectoris. Angina pectoris is a condition in which the heart does not receive sufficient blood (oxygen) supply, producing a tight sensation in the chest. This lack of oxygen supply may be due to atherosclerosis, thickening of the arteries. Nitro-glycerine was first used to treat this condition in the late 19th century. It is prescribed today in various forms (tablet, ointment, patches, and injection) for patients who suffer from angina pectoris. Nitro-glycerine is marketed under various trade names: Nitro-Dur, Nitrostat, Nitro span, Nitro-Bid, and Tridil. When used in medications, the name glyceryl trinitrate is often used instead of
