Abstract
"PROCESSO PARA PREPARAR SOLUçõES DE AMINOCARBOXILATO FéRRICO TENDO ESTABILIDADE MELHORADA, COMPOSIçãO E PRODUTO DE QUELATO FéRRICO". é divulgado um processo para preparar um quelato férrico de um ácido ácido aminopolicarboxílico onde um material contendo ferro é reagido com um quelante de ácido aminopolicarboxílico na presença de uma base, que compreende empregar reagentes de maneira tal que a razão molar de quelante para ferro seja de 0,8 a 0,99. Em concretizações preferidas o quelato é quelato de ácido etilenodiaminatetraacético de amónio férrico. Os quelatos inventivos mostram uma tendência reduzida a formar precipitado escuro quando em repouso. Este processo é particularmente adequado para uso para preparar quelatos para uso em aplicações tais como branqueamento fotográfico. Também são divulgados a composição e produtos de quelato férrico preparados pelo processo descrito.
