An oily, viscous liquid, C3H5(OH)3, colorless and odorless, and with a hot, sweetish taste, existing in the natural fats and oils as the base, combined with various acids, as oleic, margaric, stearic, and palmitic. It may be obtained by saponification of fats and oils. It is a triatomic alcohol, and hence is also called glycerol. See Note under Gelatin. [ 1913 Webster ]

It is made by the action of nitric acid on glycerin in the presence of sulphuric acid. It is extremely unstable and terribly explosive. A very dilute solution is used in medicine as a neurotic under the name of glonion. [ Written also nitroglycerine. ] [ 1913 Webster ]

☞ A great number of explosive compounds have been produced by mixing nitroglycerin with different substances; as, dynamite, or giant powder, nitroglycerin mixed with siliceous earth; lithofracteur, nitroglycerin with gunpowder, or with sawdust and nitrate of sodium or barium; Colonia powder, gunpowder with nitroglycerin; dualin, nitroglycerin with sawdust, or with sawdust and nitrate of potassium and some other substances; lignose, wood fiber and nitroglycerin.
