Reaction Steps

A portion of 8-nitroso-1,4,5-trinitro-1,4,5,8-tetraazadecalin (1.0 g, 3.3 mmoles) was slowly added to 10 ml of well-stirred 100% nitric acid maintained at 0° C. over a 15-minute time period. The solution developed a light-yellow color. It was stirred for 5 additional minutes at 0° C., then the coupling bath was removed. The stirring was continued for 5 more minutes. The reaction mixture was quenched by pouring onto 20 g of ice. A white precipitate formed and was collected by vacuum filtration. It was washed well with water and dried. It weighed 0.72 g (2.2 mmoles, 68%) and decomposed at 236° C., but darkened above 200° C. It could be recrystallized to fine crystals by dissolving in hot cyclohexanone (1 g/10 ml) and adding an equal volume of ethanol. ##STR5##
