Nitroglycerin trapping in melamine matrices

Melamine (Mel) was used as host matrix for liquid nitroglycerin (NG), to prepare Mel/NG solid powdered compounds containing up 45 wt% of this explosive. The two preparation processes purpose consisted in evaporating a solution both components, either ambient conditions or under reduced pressure by the Spray Flash-Evaporation (SFE) process. In materials, amorphous is distributed crystallized melamine inclusions, which were found be smaller size material prepared SFE materials are not stable over time: they gradually lose contain evaporation.
