Abstract
MéTODO DE PRODUçãO DE SAL DE áCIDO DINITRAMìDICO Um método de preparação de sal de ácido dinitramídico, que compreende a nitração de um composto inicial com uma mistura de ácido de nitração para formar ácido dinitramídico em uma mistura de reação. Um íon positivo é adicionado à mistura de reação e forma com o íon de dinitramida um complexo de par de íons que precipita na mistura de reação ácida, e o precipitado é separado da mistura. O ácido gasto remanescente pode ser reprocessado para recuperação de ácido para preparação de uma nova mistura de ácido de nitração.O íon positivo preferido é o íon de guaniluréia que dá um precipitado de guaniluréia dinitramida. O precipitado pode ser usado como material de partida para a preparação de outros sais de dinitramida, tal como KND e ADN. O íon de guaniluréia pode ser formado in situ no processo com a cianoguanidina sendo reagida com a mistura de reação.
