Abstract
494,277. Explosives. DEHN, F. B. (Western Cartridge Co.) July 23, 1937, No. 20460/37. [Class 9 (ii)] Propellent explosive grains are surface treated by first treating them with a solvent so as to prime or soften the surface and then treating them with the surface treating agent which may be an accelerator such as nitroglycerine or a deterrent such as dinitrotoluene, or diamyl or dibutyl phthalate. The treatment with solvent is preferably carried out while the grains are in a suspension or slurry in a non- solvent liquid which is preferably not substantially miscible with the solvent. The subsequent treatment with an accelerator or deterrent is also preferably carried out while the grains are in a suspension or slurry in a non- solvent liquid in which the accelerator or deterrent may be emulsified. This treating process is advantageously used for the powder grains produced as described in Specification 473,057. As an example, the grains are made into a slurry with four parts of water at about 40‹ C., a water emulsion of a solution of 60 per cent isopropyl acetate and 40 per cent benzene is added in amount of 5 to 15 per cent of the weight of explosive to prime the surface, and subsequently a water emulsion of 50 per cent nitroglycerine and 50 per cent toluene is added in amount sufficient to introduce 5 to 35 per cent of nitroglycerine into the explosive but deposited at the surface. The temperature is raised to 65‹ C. for thirty minutes to ensure completion of surface treatment.
