Nitroglycerine gelatine dynamite

A mixture with nitroglycol is now generally used instead of pure nitroglycerine. Gelatine dynamites are similar in composition. They contain nitroglycerine (and nitroglycol) and are gelatinized with nitrocellulose. 

Nobel invented gelatinous dynamite in 1875 by accident. He investigated the effect of nitroglycerine on the collodion (nitrocellulose in a mixture of ether and alcohol) that he used to treat a cut finger and found that it produced a tough plastic material with adjustable viscosity and high water resistance.

Stettbacher113 in 1931 described several dynamite-like explosives which contained both PETN and nitroglycerin. He called them by the general name of Penthrinit, and described simple penthrinit, gelatin penthrinit, and ammonpenthrinit. Naoum114 later in the same year reported comparative tests of ammonpenthrinit and gelatin dynamite, as follows. 

The French also have permissible explosives containing both ammonium nitrate and nitroglycerin (gelatinized), with and without saltpeter. These are called Grisou-dynamites or Grisoutines. 

Taylor and Rinkenbach found that 0.05-gram portions of hexa-methylenetriperoxidediamine, pressed in No. 8 detonator capsules under a pressure of 1000 pounds per square inch and fired by means of a black-powder fuse crimped in the usual way, caused the detonation of ordinary 40% nitroglycerin dynamite and of a gelatin dynamite which had become insensitive after storage of more than a year. The velocity of detonation of HMTD, loaded at a density of 0.88 in a column 0.22 inch in diameter, was found by the U. S. Bureau of Mines Explosives Testing Laboratory to be 4511 meters per second.

Quebrachitol nitrate is a transparent, viscous liquid, which is insoluble in water and acid. The compound is quite stable and much less sensitive then nitroglycerine. Quebrachitol nitrate shows excellent use as a high power substitute for nitroglycerine in dynamites and high performance gun propellants. It can also be used in making blasting gelatins with ammonium nitrate and fuel oil.
