PREPARATION OF AMINOPOLYCARBOXYLATE-FERRIC SOLUTIONS WITH IMPROVED LONG-TERM STABILITY

摘要

A process for producing a ferric aminopolycarboxylic acid chelate withimproved long term stability is disclosed. The process involves heating amixture of iron oxide, ammonia and aminopolycarboxylic acid chelant at anelevated temperature for a sufficient time to improve the stability of theformed chelate.
