The solution is then evaporated to dryness first in a water jet vacuum and later in a high vacuum. The white mixture obtained is pulverized in the grater and then dried over silica gel in a vacuum drying cabinet at 40 ° C. for at least 20 hours. 120 g of an explosive with an explosion heat of 769 cal / g are obtained. The melting point of this substance cannot be determined, it begins to foam at around 200 o C. pH of a solution of 1 g in 20 ml of water = 2.75. Water solubility: about 67 g / 100 ml (25 o C).
