Abstract:
Three new procedures were developed for preparing HMX from hexamine, one involving TAT as the intermediate; the others, DADN and DANNO. The DADN process was studied in some detail; the other two were not developed beyond the exploratory stage. Overall yield (hexamine to HMX) in the DADN process is about 13% higher than that of the conventional Bachmann process, and the acetic anhydride requirement is considerably lower. The first two steps were demonstrated in continuous pilot plant operation, yielding about 14 lb/hour of DADN in simple equipment. Application of the inert carrier concept (ICP) did not show promise. A cost study indicated that the DADN process offered no advantage over the Bachmann, mainly because two additional acids (sulfuric and polyphosphoric) are used. (Author)
