Fremgangsmåte for fremstilling av guanylureadinitramid

En metode for fremstilling av salter av dinitramidsyre som omfatter nitrering av en utgangsforbindelse med en blanding av nitrersyrer for å danne dinitramidsyre i en reaksjonsblanding. Et positivt ion er tilsatt til reaksjonsblandingen og danner et ioneparkompleks med dinitramid ionet som feller ut...

description En metode for fremstilling av salter av dinitramidsyre som omfatter nitrering av en utgangsforbindelse med en blanding av nitrersyrer for å danne dinitramidsyre i en reaksjonsblanding. Et positivt ion er tilsatt til reaksjonsblandingen og danner et ioneparkompleks med dinitramid ionet som feller ut i den sure reaksjonsblandingen og bunnfallet blir separert fra blandingen. Den resterende oppbrukte syren kan bli tilbakeført for gjenvinning av syren for fremstilling av en ny nitrerende syreblanding. Det foretrukne positive ionet er guanylurea ionet som fører til en utfelling av guanylurea dinitramid. Bunnfallet kan bli brukt som startmateriale for fremstilling av andre dinitramid salter, slik som KDN og ADN. Guanylurea ionet kan bli dannet in situ under prosessen ved at cyanoguanidin blir reagert med reaksjonsblandingen. A method of preparing salt of dinitramidic acid, comprising nitration of an initial compound with a nitrating acid mixture to form dinitramidic acid in a reaction mixture. A positive ion is added to the reaction mixture and forms with the dinitramide ion an ion pair complex which precipitates in the acidic reaction mixture, and the precipitate is separated from the mixture. The remaining spent acid can be reprocessed for recovery of acid for preparation of a new nitrating acid mixture. The preferred positive ion is the guanylurea ion which gives a precipitate of guanylurea dinitramide. The precipitate can be used as starting material for preparation of other dinitramide salts, such as KDN and ADN. The guanylurea ion can be formed in situ in the process by cyanoguanidine being reacted with the reaction mixture.
