Nitroglycerin (NG) (alternative spelling of nitroglycerine), also known as trinitroglycerol (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless or pale yellow, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester.
William Murrell (1853–1912) was an English physician, clinical pharmacologist, and toxicologist. Murrell is best known for being one of the first to recognize the clinical benefits of glyceryl trinitrate (also known as nitroglycerin) for the management of patients with angina pectoris.
Nitroglycerin was written about as early as 1846 [5] [6] and came into medical use in 1878. [7] [8] [9] The drug nitroglycerin is a dilute form of the same chemical used as the explosive, nitroglycerin. [9] Dilution makes it non-explosive. [9]
Ascanio Sobrero (12 October 1812 – 26 May 1888) was an Italian chemist, born in Casale Monferrato.He studied under Théophile-Jules Pelouze at the University of Turin, who had worked with the explosive material guncotton.
After this, Alfred founded the company Nitroglycerin Aktiebolaget in Vinterviken to continue work in a more isolated area and the following year moved to Germany, where he founded another company, Dynamit Nobel. [2] Despite the invention of the blasting cap, the instability of nitroglycerin rendered it useless as a commercial explosive.
A seminal work of traditional Chinese medicine was the Huangdi neijing (Yellow Emperor's Inner Canon) compiled between the 3rd and 2nd centuries BC (i.e. originating in the Warring States period), which viewed the human body, its organs and tissues through the lens of the metaphysical five phases and yin and yang, and stated a belief in two ...
Gelignite (/ ˈ dʒ ɛ l ɪ ɡ n aɪ t /), also known as blasting gelatin or simply "jelly", is an explosive material consisting of collodion-cotton (a type of nitrocellulose or guncotton) dissolved in either nitroglycerine or nitroglycol and mixed with wood pulp and saltpetre (sodium nitrate or potassium nitrate).
Nitration gives nitroglycerin, an essential ingredient of various explosives such as dynamite, gelignite, and propellants like cordite. Nitroglycerin under the name glyceryl trinitrate (GTN) is commonly used to relieve angina pectoris , taken in the form of sub-lingual tablets, patches, or as an aerosol spray.
