摘要： The disclosure relates to a method for producing composite explosives of the type hexotonal and octonal by the intermediary of a two-stage wet granulation process comprising a first granulation stage for producing primary granules of a certain amount of TNT (the primary TNT) suspended in water, together with other desired components in the explosive, with the exception of the aluminum powder, which, in its turn, is mixed into the remaining amount of secondary TNT in order thereafter, in a secondary granulation stage, to be added to the mixing water with the primary granules suspended therein, for a successive build-up of their surface layer.

摘要： The disclosure primarily relates to a method of phlegmatizing crystalline or otherwise particulate explosive substances or compositions in which these are included, by first coating the discrete particles with a thin layer of oxazolin wax in order thereafter to carry out a conventional wet-granulation with a true phlegmatization agent or a binder agent, such as one of the wax types included under different explosive standards or a plastic composition. The invention also concerns products manufactured according to said method.

摘要： The present invention relates to a method of working up and recovering returned explosives which are principally of the military type and which contain both fusible and non-fusible crystalline substances. In accordance with the invention, the returned explosive is treated in a multi-stage process which includes a first leaching stage for removing the non-crystalline, preferably fusible, component of the explosive in the form of trotyl, wax or plastic. The substance used in the leaching stage, principally toluene, does not affect the crystalline components of the explosive. The collected leaching liquid is separated off and the toluene, together with its dissolved content of trotyl or wax, is conveyed onwards for working up. The toluene which is recovered during the working up is returned to the process while the remaining filtrate from the filtration stage is treated with solvent which dissolves the crystalline high-energy explosives octagen and hexagen, respectively, which are relevant in this connection, which explosives, in a subsequent process stage, are precipitated out in the form of new crystals which, after a possible recrystallization, are ready to be reused. The solvent which is used in this connection is returned to the process.

摘要： The present invention relates to a method for the recrystallization of the high explosives HMX and RDX. According to the invention, the explosive is dissolved in a low molecular weight, liquid (at room temperature) lactone, after which the degree of saturation of the solution obtained, is changed by either lowering the temperature or by diluting with water.This method produces, depending on the crystallization method chosen, .beta.-HMX crystals or RDX crystals of either 50-1500 .mu.m or 5-50 .mu.m median particle diameter respectively.
