The thermal decomposition of RDX at temperatures below the melting point. IV. Catalysis of the decomposition by formaldehyde

Author: Batten, J (1971) Australian Journal of Chemistry 24:2025. HERO ID: 1485426

[Less] The effect of formaldehyde (50000) on the decomposition of RDX (121824) at temperatures below the melting . . . [More] The effect of formaldehyde (50000) on the decomposition of RDX (121824) at temperatures below the melting point was investigated in-vitro. The hypothesis was suggested that, if catalysis by formaldehyde exists, then the activation energy of the decomposition in the presence of added formaldehyde should be less than that obtained in the presence of nitrogen (7727379). In each experiment, the weight of dry paraformaldehyde (30525894) was adjusted so that the pressure of formaldehyde at the reaction temperature was approximately constant at about 130 millimeters mercury. The temperature range studied was 170 to 197 degrees-C. At constant temperature, the sample, in the presence of formaldehyde, underwent the liquefaction process at a lower percentage of decomposition than was observed for the decomposition in the presence of nitrogen. A significant increase was observed in the positive catalytic effect of the formaldehyde, associated with decreasing reaction temperature. The kinetics of the decomposition were not altered by formaldehyde. The activation energy with the sample spread in the presence of added formaldehyde was about 44 kilocalories per mole at all stages of the decomposition to the end of the maximum rate. There was a marked increase in the accelerating effect of formaldehyde as the reaction temperatures decreased. The author concludes that previous values of activation energy are less than the energy of the weakest bond in RDX because of catalysis of the reaction by the decomposition product formaldehyde.

[More] By the use of a metal indentation techinque, microscopic transverse or side-running shock waves can be detected in composition C-4, an explosive consisting largely of cyclonite (RDX) with organic plasticizers. The minimum wave spacing observed is approximately 0.05 millimeters. with a lateral velocity of about 6.5 millimeters per microsecond. The instability was demnostrated in cylindrically divergent detonation waves.

[More] Composition C-4 is a putty-like explosive material that is widely used in Vietnam by US forces. It is found in Claymore mines and in standard demolition kits. Detonation is usually accomplished with a blasting cap. The main chemical component of Composition C-4 is RDX, which has been used as an explosive since World War I. The chemical structure of RDX is cyclotrimethylenetrinitramine, which is similar to TNT. Although insoluble in water, in 80 per cent ethanol RDX is broken down to its constitutent parts of methylamine, nitrous acid, ammonia, and formaldehyde. Composition C-4 also contains small amounts of polyisobutylene, motor oil and sebacate.

[More] Composition C-4 is the most common plastic explosive employed by the military in Vietnam. Ingestion is followed in a few hours by multiple generalized seizures, hematuria, severe nausea and vomiting, muscle twitching, and mentation changes. Six patients requiring hospitalization were treated by gastric lavage, maintenance of airway, control of seizures, monitoring of urine volume, and maintenance of fluid and electrolyte balance. No fatalities were observed.

Ingestion of an explosive material, composition C-4: A report of two cases

[More] The accidental or intentional ingestion of toxic substances frequently results in life threatening complications of various types. Frequently, the nature of the offending substance is unknown to the physician who must care for the critically ill or potentially critically ill patient. The following case reports describe two patients who, while intoxicated with ethanol, ingested unknown quantities of Composition C-4, a plastic-type explosive. This substance is widely available in Vietnam. Since there have been no previous reports in the literature of ingestion of this substance, the two cases are reported in some detail. Comments are made about the composition and chemical structure of C-4 together with a brief discussion of known toxic effects of some of its breakdown products.

Factors in Selecting and Applying Commercial Explosives and Blasting Agents

[More] The properties of explosives are reviewed including strength, velocity, density, detonation pressure, water resistance and fume class. Criteria for the selection of an explosive are discussed: physical conditions such as hardness and density of the work, geological features, moisture conditions, and available ventilation. The ingredients used in the manufacture of high explosives are classified as explosive bases, combustibles, oxygen carriers, antacids and sorbents. Three types of dynamites are described: straight nitroglycerin (55630), high density ammonia (7664417), and low density ammonia. The properties and uses of blasting gelatin, straight gelatin, ammonia gelatin, and semi gelatin are presented. Dry blasting agents and slurry blasting agents are discussed. Military explosives such as trinitrotoluene (118967), and cyclotrimethylenetrinitramine (121824) are presented. Devices used for initiating high explosives are discussed: blasting caps, electric blasting caps, delay blasting caps, and cap fuses. The author suggests that though this report is general in nature, more information on specific explosives can be obtained from any of a number of companies.
