A parametric study of the synthesis of 2,3,4,6-tetranitroaniline
Source abstract
Abstract
Abstract As part of the synthesis scale-up of the explosive 7-amino-4,6-dinitrobenzofuroxan (ADNBF), the mixed-acid preparation of 2,3,4,6-tetranitroaniline (TNA) from m-nitroaniline has been reinvestigated. Yields of 80–97% were obtained under extremely mild reaction conditions. During the course of our study we had an incident which resulted in sudden and rapid ejection of reaction material onto laboratory personnel. The reaction conditions which underlie this potential hazard have been identified and safe reaction conditions are discussed. The improved procedure is now regarded as very safe with an easily controlled exotherm.
