• Verwenden

  Pentaerythritol tetranitrate (PETN) is a high explosive, often used as the booster in artillery ammunition. It is frequently used as a detonation fuse, which is a form of primacord in which PETN powder is wrapped in waterproof fabric.

• Verwenden

  Pentaerythritol tetranitrate is used for chronic cardiac insufficiency. It prevents angina pectoris attacks and eases their course.

• Verwenden

  Mainly in the manufacture of detonating fuse (Primacord), a waterproof textile filled with powdered PETN.

• Definition

  ChEBI: A pentaerythritol nitrate in which all four hydroxy groups of pentaerythritol have been converted to the corresponding nitrate ester. It is a vasodilator with properties similar to those of glyceryl trinitrate, but with a more prolonged duration of action, and is used for treatment of angina pectoris. It is also one of the most powerful high explosives known and is a component of the plastic explosive known as Semtex.

• Manufacturing Process

  Cooling water was turned on and 420 parts nitric acid of 94% strength was introduced into the nitrator. The amount of acid was such that the ratio of nitric acid to pentaerythritol was 4.29. The agitator was started and the agitator speed adjusted to 120 rpm. 92 parts pentaerythritol, which had been screened previously through a 14-mesh screen was used in each charge. About 45 parts pentaerythritol was added to the nitrator at such a rate that the temperature in the nitrator gradually rose to 110°F. This required about 12 minutes. Time was allowed for the temperature rise to cease before each succeeding increment of material was added.
  After reaching 110°F the charge was maintained at about said temperature from 12 to 14 minutes during which time approximately 30 parts pentaerythritol was added to the nitrator. During the following 14 minutes, approximately, the remainder of the 92 parts pentaerythritol was added in like manner to the charge and the temperature gradually reduced. The pentaerythritol was introduced into the acid in finely divided and welldispersed particles and not in large unitary quantities. The entire 92 parts of pentaerythritol tetranitrate was introduced in 35 to 40 minutes. The pentaerythritol thus obtained was separated from the spent acid by filtering or drowning in water. To recover the spent acid the charge was passed onto a nutsch and filtered. The crude product was washed with water, then with a weak water-soluble alkali solution, such as sodium carbonate for example, and subsequently with water in order to remove the acid.
  After the removal of acid, the nitrate was dried by suction on the nutsch for about 15 minutes. The dried material was refined by means of acetone treatment or other suitable refining means. About 210 parts refined pentaerythritol tetranitrate per charge was obtained.

• Reaktivität anzeigen

  Pure PENTAERYTHRITE TETRANITRATE is an explosive. Severe explosion hazard when shocked or exposed to heat. Explodes when heated to 205-215°C. Highly dangerous when mixed with oxidizing agents. On decomposition Pentaerythritol tetranitrate emits highly toxic fumes of NOx (Sax and Lewis, 1987 pp. 699-700).

• Health Hazard

  Some are toxic and may be fatal if inhaled, swallowed or absorbed through skin. Contact may cause burns to skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.

• Health Hazard

  Skin contact can cause dermatitis. There is no report of any major adverse effects in humans. However, drawing a parallelism with other nitroorganics of similar structures, PETN is expected to cause poisoning with symptoms of headache, nausea, abdominal pain, and dyspnea.

• Brandgefahr

  PETN is a high explosive, as powerful as cyclonite. It is more sensitive than TNT to shock. It explodes on percussion or heating. The detonating temperature is 210°C (410°F). The detonation velocity is 7.9 km/s.

• Sicherheitsprofil

  Human systemic effects by ingestion: dermatitis. Effects are sirmlar to those of nitroglycerin, i.e., headache, weakness, and fall in blood pressure. Very low oral toxicity. Severe explosion hazard when shocked or exposed to heat. It explodes at 215’C. On decomposition it emits hghly toxic fumes of NO,; can react vigorously with oxidizing materials. Used in detonators and explosive specialities. See also NITRATES and EXPLOSIVES, HIGH.

• Synthese

  Pentaerythritol tetranitrate, 2,2-bis(hydroxymethyl)-1,3- propandioltetranitrate (19.1.2), is also synthesized by a nitration reaction of pentaerythritol with nitric acid, but using 2,2-bis(hydroxymethyl)-1,3-propandiol instead of glycerol as the starting material.

  

• mögliche Exposition

  First introduced following WWII, PETN shares the same chemical family as nitroglycerine. It is 70% more powerful than TNT. Used in the manufacture of fuses for detonation and explosive specialties, including the plastic explosive, Semtex, and in blasting caps. PETN is also used as a medical vasodilator to lower blood pressure by widening blood vessels to improve blood flow. PRTN has been used in terrorism attempts in 2001 by the so-called “shoe bomber,” in 2009 by the “underwear bomber,” and most recently in October 2010, hidden in printer cartridges being shipped internationally by passenger jet.

• läuterung methode

  Crystallise pentaerythritol tetranitrate from acetone or acetone/EtOH. When crystallised from H2O at 0o, it may have m 26-28o (hydrate). It detonates more easily than TNT on percussion. The O-acetate, when crystallised from EtOH, has m 87-88o. Although it has been distilled at 60o/2mm, distillation should NOT be attempted as it is VERY EXPLOSIVE. Itis a vasodilator. [Marans et al. J Am Chem Soc 76 1304 1954, Camp et al. J Am Chem Soc 77 751 1955, Beilstein 1 IV 2816, 2 IV 264.]

• Inkompatibilitäten

  Treat PETN as an unstable explosive. Rapid heating can cause detonation when heated to 210C. PETN is a dangerous high explosive and a strong oxidizer. PETN normally requires a blasting cap or other kind of detonator but may decompose explosively from concussion, shock, friction, static charges. Keep away from combustible materials; other oxidizers, for example, nitrates and permanganates. Contact with sulfur trioxide may cause detonation. Contact with reducing agents, e.g., zinc and alkaline metals may cause explosion. May explode in the presence of strong bases (i.e., sodium or potassium hydroxide). May react with heavy metals.

• Waste disposal
