A process for synthesizing 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo-[5.5.0.0.sup.5,9 0.sup.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
A process for synthesizing 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo-[5.5.0.0.sup.5,9 0.sup.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.degree. C. to about 70.degree. C. and maintaining the medium from 55.degree. C. to about 70.degree. C. to permit the hexa-substituted piperazine derivative and nitronium anions to react and form the TEX. At least one NO.sub.x scavenger is added to the medium, preferably before the addition of the hexa-substituted piperazine derivative, to increase TEX yield.

[ What is claimed is:] [1.] A process for synthesizing 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo-[5.5.0.0.sup.5,9 0.sup.3,11 ]-dodecane, comprising:(a) combining at least one hexa-substituted piperazine derivative with a medium, said medium being in a range from about 55.degree. C. to about 70.degree. C. in temperature and comprising at least one nitronium anion source and at least one acid sufficiently strong to generate nitronium anions from the nitronium anion source, and maintaining the medium from about 55.degree. C. to about 70.degree. C. to permit the hexa-substituted piperazine derivative and nitronium anions to react and form 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo-[5.5.0.0.sup.5,9 0.sup.3,11 ]-dodecane;(b) combining the medium with at least one NO.sub.x scavenger; and(c) subsequent to said (a) combining of the hexa-substituted piperazine-derivative with the medium, cooling the medium into a sufficiently low temperature range to precipitate the 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo-[5.5.0.0.sup.5,9 0.sup.3,11 ]-dodecane.
