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
trinitroglycerin and
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
