Percentage expresses HPLC recovery of 2-bromo-4,6-dinitroaniline (BDNA). Additional thin layer chromatography measurements indicate anaerobic transformation BDNA... 

The rock explosives used in the U.S.A. are similar in composition to those used in Europe. In addition to blackpowder (with Chilian saltpetre) dynamites with the composition tabulated below are used extensively.
