Abstract

"MéTODO PARA PREPARAR ETILENODIAMINO-N, N' - DISSUCCINATO DISSóDICO". é revelado um prodesso para isolar o sal dissódico de uma mistura de isómeros mesos e racêmicos de sais de sódio do ácido N, N' - etilenodiamina dissuccínico, a partir de soluções aquosas alcalinas, ajustados-se o pH da solução alcalina entre 5 a 10 por adição de um ácido, seguido pela recuperação de um sal dissódico sólido. A mistura de isómeros pode ser preparada pela reação do maleato de sódio com etilenodiamina em uma solução aquosa alcalina. Esse método é particularmente apropriado para preparar o sal dissódico tetraidatado e evitar a formação de ácido livre. O produto final biodegrada mais rapidamente que o ácido N, N, N', N' - etilenodiaminotetracético (EDTA).
