| abstract | 497,145. Explosives. TRIGGS, W. W. (United States Powder Co.) March 6, 1937, No. 555. Drawings to Specification. [Class 9 (ii)] An explosive mixture comprises a nitrocompound, such as dinitrobenzene, trinitrobenzene, dinitrotoluene, trinitrotoluene, picric acid, or styplinic acid, an oxidizer, such as an alkali, ammonium or alkaline earth nitrate or lead nitrate and, in addition, a nitro-derivative of naphthalene and an organic promoter consisting of one or more aliphatic or aromatic compounds in which the " molecular length," calculated from the values of atomic radii and bond angles given in the Specification, is within 0À1 angstrom unit of being equal to 3À83, 4À19, 4À84 or 5À13 angstrom units. The term " molecular length is defined as being the equilibrium distance between the atoms (exclusive of hydrogen atoms), which are farthest apart from each other in a molecule of either the aromatic or aliphatic type. Examples of such an organic promoter are ethyl acetate, methyl propionate, propanol, butanol, proprionic acid, lactic acid, butyric acid, alanine, butyric aldehyde, benzyl alcohol, benzylamine, benzaldehyde, benzoic acid, salicylic acid, 1À2-dichlorethylene or glycme. In general, the amount of promoter added to the nitronaphthalene is from À005 per cent to 2 per cent by weight of the entire explosive mixture. In making the explosive, the nitronaphthalene and the nitro-compound are melted together and to the molten mass is added the promoter and the necessary moisture, which is generally in the form of a 50 per cent calcium nitrate or aluminium nitrate solution and finally the powdered and warmed nitrate is incorporated in the mixture so that the particles of nitrate are coated with the organic explosive mixture. To produce a plastic powder, an additional quantity of a suitable mixture containing generally tetranitronaphthalene, dinitrotoluene and the promoter is added to the mixed explosive. Various examples are given in the Specification. |
