This substance was first prepared by H. Ficheroulle and A. Kovache in 1949. This explosive is somewhat stable to mechanical shock but will explode when brought into contact with flame. The solid will pull moisture out of the air, being hygroscopic. The more moisture it contains, the less likely it is to explode, conversely the drier it is the more likely it is to explode. Keep this material tightly stoppered and perhaps damp when storing, but keep it dry for detonating. Thus far there have been no practical military or civilian applications for this compound.
|lead nitrate||graduated cylinder|
|sodium benzoate||stirring rod|
Dissolve 2.4 g of lead nitrate in 50 mL of water heated to 90-95 °C in a beaker, and add, with stirring, a concentrated solution of sodium benzoate , prepared by neutralizing 2 g of benzoic acid with 0.6 g of sodium hydroxide. Evaporate the mixture on a water bath to a small volume while the liquid still remains clear. Cool and add 50 mL of 95% ethyl alcohol. This results in a very fine, light yellow precipitate, which is separated by vacuum filtration. After drying at 50 °C, the yield should be about 41.82%. A moisture content in excess of 20% will make this explosive nearly impossible to detonate. You will need a graduated cylinder for measuring liquids, a stirring rod for mixing, and a thermometer to monitor the temperature.
