Explosives dynamite

Dynamite is probably the best known explosive. Dynamite is composed of either wood pulp or diatomaceous earth soaked in nitroglycerin and pressed into a stick shape. Nitroglycerin is very unstable—it can explode if it is disturbed—so the wood pulp helps to stabilize the dynamite.

Alfred Nobel invented the explosive dynamite in the 1860s and continued to develop other explosives. In his will he used his fortune to establish the Nobel Prizes. 

SAFETY PROFILE Permissible explosives are essentially high explosives (dynamite) modified by the introduction of dopes. The function of the dopes in general is to decrease flame temperature, and to a smaller extent, the length and duration of flame, when the explosive is converted from a solid into a gas, i.e., when it is fired or detonated. The designation permissible is given to an explosive of modified dynamite tjqje after it has passed certain tests designated by the Federal Bureau of Mines. The permissible character of such explosives depends not only upon the ingredients in the explosive, but also on certain well-defined specifications as to...

Because nitroglycerin is so unstable, it is difficult to use as a controllable explosive. The Swedish inventor Alfied Nobel (T RGURE 8.16) found that mixing nitrc lycerin with an absorbent solid material such as diatomaceous earth or cellulose gives a sohd explosive (dynamite) that is much safer than liquid nitrc ycerin. 

Nobel, Alfred Bernhard (1833-96) Swedish chemist and engineer who discovered the element nobelium and invented a safer explosive by mixing nitroglycerin with the diatomaceous earth kieselguhr. He called this explosive dynamite. It earned him so much money that he was able to leave more than 9 million for the establishment of the Nobel Prize. 

It might at first seem impossible that nitroglycerine, used to make the first modem blasting explosive, dynamite, could also be used safely to make propellants. Nitroglycerine requires the shock from a blasting cap (or detonator) to canse reliable detonation of the material. When blended with less explosive materials and ignited with flame rather than shock, it is capable of burning, and was found to be qnite nsable and effective in propellant formnlations. 

G. is primarily used as - explosive (dynamite), in - fire fighting in oil wells and in rocket propellants. It is also used in medicine as a vasodilator in coronary spasm.
