摘要：
Aminonitrobenzodifuroxan (CL-18) is prepared by directly converting pentanitroaniline to aminonitrobenzodifuroxan with heat in the presence of an excess of sodium azide. The pentanitroaniline is prepared in high yield from 3,5-dinitroaniline with a mixture of nitric acid and sulfuric acid in which the final sulfuric acid concentration is from 99.0 to 99.5%.
