Abstract
(EN)
The invention provides a method of forming an iron hydroxypyrone compound comprising reacting a hydroxypyrone with a non-carboxylate iron salt in an aqueous solution, and precipitating the iron hydroxypyrone compound from the aqueous solution having a pH of greater than 7.
(FR)
La présente invention concerne un procédé de formation d'un composé d'hydroxypyrone de fer, consistant à faire réagir une hydroxypyrone avec un sel de fer non carboxylate dans une solution aqueuse, et à précipiter le composé d'hydroxypyrone de fer à partir de la solution aqueuse ayant un pH supérieur à 7.
