|benzalaminoguanidine nitrate||molecular mass
I don't have much information on this explosive other than it is a derivative of the explosive nitroguanidine as it uses that material as its precursor. I would assume it has properties similar to nitroguanidine. This explosive may also be called benzaldehyde guanylhydrazone nitrate.
|acetic acid||Erlenmeyer flask|
|ethyl alcohol||graduated cylinder|
|nitric acid||stirring rod|
Into a 300-mL Erlenmeyer flask, add 26 g of zinc dust, 10.4 g of nitroguanidine, and 150 mL of water. Slowly add 42 mL of glacial acetic acid from a small beaker at such a rate that the temperature of the mixture does not rise above 40 °C. The liquid at first turns yellow because of the formation of nitrosoguanidine but becomes colorless again when the reduction is complete. After all the zinc has disappeared, add 45 mL of concentrated nitric acid , then 102 mL of benzaldehyde. Shake the mixture well to mix the contents then scratch the inside of the flask with a glass stirring rod to facilitate the precipitation of benzalaminoguanidine nitrate crystals. The product can be purified by recrystallizing from water or from ethyl alcohol. You will need a graduated cylinder for measuring liquids and a thermometer to monitor the temperature.
