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.

标题 :Synthesis of bis(2,2-dinitropropyl) formal (BDNPF)

摘要:A nonsolvent process of synthesizing bis(2,2-dinitropropyl)formal (BDNPF) is disclosed. In the process, 2,2-dinitropropanol (DNPOH) is reacted at low temperature with a formaldehyde source in the presence of a protic acid catalyst, such as H 2 SO 4 , HCl, H 3 PO 4 , or HBr. To inhibit byproduct formation, the reaction temperature is maintained from about -30° C. to 30° C. Upon completion of the reaction, the reaction solution is quenched with water and washed with an aqueous hydroxide ion solution. The hydroxide ion concentration should be sufficient to neutralize the protic acid catalyst during the quenching step and to solubilize unreacted 2,2-dinitropropanol as well as other aqueous soluble byproducts in the reaction solution. The BDNPF product is extracted with a low boiling temperature polar organic solvent, such as methyl tert-butyl ether (MTBE) or equivalent solvent. The organic solvent is evaporated to yield usable BDNPF product. The resulting yield is at least 60% based on the starting quantity of 2,2-dinitropropanol.

摘要:A nonsolvent process of synthesizing bis(2,2-dinitropropyl)acetal (BDNPA) is disclosed. In the process, 2,2-dinitropropanol (DNPOH) is reacted at low temperature with an acetaldehyde source in the presence of an acid catalyst, such as a Lewis acid catalyst or protic acid catalyst. To inhibit by product formation, the reaction temperature is maintained from about -30° C. to 30° C. Upon completion of the reaction, the reaction solution is quenched with water and washed with an aqueous hydroxide solution. The hydroxide concentration should be sufficient to neutralize any acid formed during the quenching step and to solubilize unreacted 2,2-dinitropropanol as well as other aqueous soluble byproducts in the reaction solution. The BDNPA product is extracted with methyl tert-butyl ether (MTBE) or equivalent solvent. The organic solvent is evaporated to yield usable BDNPA product. The resulting yield is at least 50% based on the starting quantity of 2,2-dinitropropanol.
