Improved process for manufacturing an explosive eutectic composition comprising about 46% by weight ammonium nitrate, about 46% by weight ethylene diamine dinatrate, and about 8% by weight potassium nitrate. First, potassium hydroxide, ammonia, water, nitric acid, and ethylene diamine are reacted in aqueous solution to produce the indicated components of the eutectic mixture. Then the solution is cooled to supersaturate each solute thereof and passed through a continuous crystallizer to crystallize the components of the product in eutectic proportions. The product is then separated from the mother liquor, which is recycled. The process can be operated continuously and safely without producing by-products or employing solvents which must be evaporated from the composition or disposed of.
改进的制造爆炸性共晶组分的工艺包括约46%重量的硝酸铵、约46%重量的乙二胺二硝酸盐和约8%重量的硝酸钾。首先,在水溶液中反应氢氧化钾、氨、水、硝酸和乙二胺,以产生共晶混合物的指示成分。然后将溶液冷却以使每种溶质超饱和,并通过连续结晶器使产品的成分以共晶比例结晶。然后将产品与母液分离,而母液则被回收利用。该工艺可以连续、安全地操作,不会产生副产品,也不需要使用必须从组分中蒸发或处理的溶剂。
