Definitions

  • glycol dinitrate unless one or the other of these individual compounds is especially intended) are known substances having properties which render them suitable as explosives.
  • propylene-glycol dinitrate-containing highly underbalanced explosives are highly insensitive to impact. It is also known that highly overbalanced as well as underbalanced explosives are generally insensitive to impact, but that the sensitivity to impact will increase on oxygen-balancing, so that mixtures of considerable sensitivity will be obtained. It has now surprisingly been found that propylene-glycol dinitrate-containing explosives can be produced which maintain their high insensitivity to impact even after oxygen-balancing.
  • nitroglycol the dinitrate of ethylene glycol
  • our novel oxygen-balanced explosives present considerable advantages.
  • the use of nitroglycol is, as known, connected with physiological drawbacks. When admixed with nitroglycerine, the nitroglycol will increase the vasodilatory effect on the blood veins of man which is particularly manifested as headache and indisposition. Another reason why mixtures of nitroglycol with nitroglycerine are physiologically disadvantageous is ascribed to the poisonous effect of the nitroglycol itself.
  • the present invention relates to an explosive having an improved physiological acceptance and a low sensitivity to impact, consisting of or containing propylene-glycol dinitrate, and one or more inorganic oxygen-delivering salts.
  • One important characterizing feature of the explosive according to the invention is that the oxygen-delivering inorganic salt or salts are present in a suflicient amount to substantially oxygen-balance the explosive.
  • the explosives according to the invention possess a combination of high insensitivity to impact with an excellent physiological acceptance, they represent a valuable advance in the field of explosives.
  • the propylene-glycol dinitrate can either be the only liquid ingredient of the explosive oil, or it can be admixed with other liquid ingredients. If the explosive oil is a mixture of different substances, may contain up to about 50 percent of nitroglycerine. It is natural that the explosive must not contain any substantial amounts of nitro- GELATINIZING OF THE EXPLOSIVE OIL
  • An explosive oil, consisting of propylene-glycol dinitrate or at least mainly of this substance, does not form a gel with nitrocellulose at usual temperatures. In order to attain gelatinizing, increased temperatures Will be required. In this connection, that, especially if subjected to alternating freezing and thawing, rgels produced at high temperatures will gradually release their oil.
  • gelatinizing aids may generally be mentioned hydrogen bond-forming substances. Such aids will be effective in proportion to their ability to form such bonds.
  • Such aids there may be mentioned:
  • Eth'ers With lower alkyls monosubstituted ethyleneglycol and diethylene-glycol in which the lower alkyls may be methyl, ethyl, propyl and butyl, such as glycolmonomethylether and glycol-monoethylether.
  • the explosive according to the invention may contain high brisant explosives such as trotyl, pentyl, hexogen etc. Furthermore, it may contain usual oxygen-consuming substances such as saw duct, flours of different kinds and metal powders, and usual fillers such as kieselguhr.
  • Gap test 24 mm. cartridge
  • Example 2 A plastic explosive was made up by mixing together the following ingredients:
  • the oxygen-balance of the explosive was +40%.
  • the properties of the explosive were the following:
  • volume weight 1.45 Gap test (25 mm. cartridge), mm. at 20 C. -180 Impact sensitivity test according to Kast, 2 kg.
  • Example 3 A plastic explosive was made up by mixing together the following ingredients:
  • the oxygen-balance of the explosive was +33%.
  • the properties of the explosive were the following:
  • volume weight 1.49 Gap test (25 mm. cartridge), mm. at 20 C. 80-100 Impact sensitivity test according to Kast, 2 kg.
  • volume weight 1. 1 1. 46 Detonation velocity, kITL/S 4. 7 2. 75 Gap test (25 mm. cartridge) mm. at
  • a plastic explosive consisting of the following ingredients in the following amounts:
  • a plastic explosive consisting of the following in gredients in the following amounts:
  • An explosive composition having an improved physiological acceptance and a low sensitivity to impact comprising as its essential ingredients:
  • an explosive oil selected from the group consisting of the dinitrate of 1,2-propylene glycol, the dinitrate of 1,3-propylene glycol, and mixtures of one of these dinitrates with up to 50% by weight of nitroglycerme,
  • said oxygen-delivering inorganic salt being present in an amount to substantially oxygen balance the explosive.
  • An explosive composition according to claim 3 wherein said oxygen-delivering inorganic salt is selected from the group consisting of (a) nitrates of ammonium, alkali metals and alkaline earth metals, (b) perchlorates of ammonium, alkali metals and alkaline earth metals and (c) chlorates of alkali metals and alkaline earth metals.
