Definitions

• An explosive composition which does not exude at temperatures below 100 C. comprises at least one of hexogene (cyclotrimethylenetrinitramine) or octogene (eyclotetramethylenetetranitramine) in intimate mixture with at least one of 2,4,6-trinitro-N-methylaniline or 2,4,6-trinitro-N,N'-dimethylaniline.
• the composition may also contain at least one additive of the group consisting of waxes, graphite and metallic powders.
• one method of filling munitions comprises pouring a fluid explosive mixture, which then solidifies and hardens.
• explosive mixtures include on the one hand tolite (trinitrotoluene, TNT) and on the other hand nitramines such as hexogene (cyclotrimethylenetrinitramine) or octogene (cyclotetramethylenetetranitramine) and also, as required, one or more other materials such as wax, graphite and, metallic powders.
• the present invention thus relates to explosive compositions containing:
• compositions can also contain other additives, such as waxes, graphite and metallic powders.
• present invention also relates to the means for obtaining these compositions. Having regard to the high melting points of the nitrated derivatives, hot water coating at ordinary pressure cannot be used.
• METHOD 1 The direct introduction of dry hexogene or octogene into the trinitromethylaniline or trinitrodimethylaniline is the most simple method for making the mixture, but it has the disadvantage of requiring the drying of pure hexogene or octogene, which are explosives offering considerable risks when handled whilst dry.
• METHOD 2 It is of advantage therefore to prepare, for instance by one or other of methods 3 and 4, a composition containing, for example, 90 of hexogene or octogene covered with 10% of the nitrated aniline, in order to phlegmatise or otherwise protect the hexogene or octogene.
• This dry granular composition is then introduced into a bath of the molten nitrated aniline, as is the current practice in the case of hexogene/tolite mixtures.
• the third method mentioned consists in coating hexogene or octogene with the nitrated aniline in water under pressure, the temperature being sufliciently high for the nitrated aniline to be molten, the upper limit being given by the temperature of hydrolysis of hexogene (about C.) or of octogene (about C.).
• the fourth method is utilisable with a solvent which is immiscible or slightly miscible with water and involves dissolving the trinitromethylaniline or trinitrodimethylaniline.
• This solvent will be subsequently entrained with steam and it will remain in suspension in the water from the composition desired.
• Solvents which can be used include, for instance, aromatic hydrocarbons, nitroparaffins, esters, ketones and other oxides.
• Examples (1) g. of 2,4,6-trinitro-N-methylaniline were dissolved in a flask maintained at 120 C. by means of an oil bath. g. of hexogene recrystallised from cyclohexanone were added in stages with stirring. The mixture was then poured into a small flat dish. A yellow plate of the mixture desired was thus obtained. This pouring can also be made into a glass tube which has previously been evacuated. After cooling a cartridge is obtained having a speed of detonation (7750 m./s.) which is substantially the same as that of a cartridge of 60% hexogene, 40% tolite. The stability under vacuum at 130 C. of this mixture is better than that of a 60/40 hexogene/tolite mixture under the same conditions.
• An explosive composition which does not exude below 100 C., which consists essentially of at least one substance selected from the group consisting of hexogene and octogene plus at least one substance selected from the group consisting of 2,4,6-trinitro-N-methylaniline and 2,4,6-trinitro-N,N-dimethylaniline in intimate mixture therewith.
