Process for separating impurities from explosives, and application of the process to the determination of purity or to the determination of the composition of the impurities

摘要

In order to separate minute impurities from trinitrotoluene, a solution of trinitrotoluene in toluene is allowed to flow through silica gel having a layer thickness of a few cm, and the impurities eluted from the silica gel with acetone can then be determined qualitatively and quantitatively.
