- n. A thick, pale yellow liquid, C3H5N3O9, that is explosive on concussion or exposure to sudden heat. It is used in the production of dynamite and blasting gelatin and as a vasodilator in medicine.
Century Dictionary and Cyclopedia
- n. A compound (C3H5N3O9) produced by the action of a mixture of strong nitric and sulphuric acids on glycerin at low temperatures. It is a light-yellow, oily liquid, of specific gravity 1.6, and is a most powerful explosive agent, detonating when struck, or when heated quickly to 306˚ F. For use in blasting it is mixed with one fourth its weight of silicions earth, and is then called
dynamite. Taken internally, it is a violent poison, but in minute doses is used in medicine in the treatment of angina pectoris and heart-failure. Also called glonoin, nitroleum, blasting-oil, glyceryl nitrate, trinitrate of glyceryl, and trinitrin.
- n. alternative spelling of nitroglycerine.
GNU Webster's 1913
- n. (Chem.) A liquid appearing like a heavy oil, colorless or yellowish, and consisting of a mixture of several glycerin salts of nitric acid, and hence more properly called
glycerin nitrate; also called trinitroglycerinand glyceryl trinitrate. 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.
- n. a heavy yellow poisonous oily explosive liquid obtained by nitrating glycerol; used in making explosives and medically as a vasodilator (trade names Nitrospan and Nitrostat)
