摘要:A method for the synthesis of 2,6-Diamino-3,5-dinitropyrazine-1-oxide including nitration of 2,6-diaminopyrazine-1-oxide. The step of nitration may use nitrating agents 20% Oleum/100% HNO3, 100% HNO3 and conc. H2504/100% HNO3 or nitronium tetrfluoraoborate. The synthesis of 2,6-diaminopyrazine-1-oxide may involve both the oxidation of 2,6-diaminopyrazine, the amination of a precursor 2,6-disubstitutedpyrazine-1-oxide or direct formation of the 2,6-diaminopyrazine-l-oxide from the precursor, 2-amino-6-hydroxamino-pyrazine-1-oxide.

标 题 :Process for the large-scale synthesis of 4,10-dinitro-2,6,8-12-tetraoxa-4,10-diazatetracyclo-[5.5.0.05,903,11]-do decane

摘要:A process for synthesizing 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo-[5.5.0.0 5 ,9 0 3 ,11 ]-dodecane ('TEX') involves combining at least one hexa-substituted piperazine derivative with a medium containing at least one nitronium anion source and at least one acid sufficiently strong to generate nitronium anions from the nitronium anion source. According to this invention, TEX yield is significantly improved by pre-heating the medium to 55° C. to about 70° C. and maintaining the medium from 55° C. to about 70° C. to permit the hexa-substituted piperazine derivative and nitronium anions to react and form the TEX. At least one NO x scavenger is added to the medium, preferably before the addition of the hexa-substituted piperazine derivative, to increase TEX yield.
