How do you dispose of nitroglycerin?

Answer 1

The nitroglycerin content of angina pills is very small, and does not constitute an explosion hazard of any sort. Nitroglycerin pills should be disposed of as per the packaging insert (typically, wrapped thoroughly in newspaper, then put in trash). If you have bulk quantities of pure nitroglycerin -- more than a fraction of a teaspoon -- you have a very hazardous material that must be handled with care. Nitroglycerin is highly energetic; the detonation of a tablespoon (30cc) could amputate the hand holding the spoon and possibly kill someone. There are methods, typically involving the reaction of nitroglycerin with a base such as sodium hydroxide, for neutralizing the nitroglycerin. However, unless you are an experienced chemist or otherwise have experience in the handling of sensitive materials, you should not attempt neutralization -- or disposal -- of nitroglycerin yourself. Call your local fire department to let them know what you have. They can assist you or contact someone who can. Be aware that you may have some explaining to do, if you have more than experimental quantities and don't have an ATF license...

Answer 2

Nitroglycerin was once used as an explosive. It was so unstable, and sensitive to heat and shock, that its use as a pure material for blasting was eliminated in the 19th century. Since 1866 when Alfred Nobel discovered that nitroglycerine retains its explosive power while loosing its "touchy" nature when mixed with sawdust or diatomaceous earth, nitroglycerin is the explosive agent ingredient in dynamite. Nitroglycerin is also a medication used to treat chest pain associated with restricted blood flow to the heart. In this application it is a "pill" dissolved under the tongue.
