Process for obtaining hexa-m-acetato-m3-oxo-tris(aqua)triferrum(III) nitrate in solid form and in the form of aqueous solution

摘要

The invention relates to chemistry, in particular to a process for obtaining hexa-µ-acetato-µ3-oxo-tris(aqua)triferrum(III) in solid and liquid form that can be used in different fields, especially in agriculture as antichlorosic complex.The process, according to the invention, provides for the sedimentation of iron(III) hydroxide from any water-soluble iron(III) salt, washing and treatment thereof with acetic and nitric acids in the molar ratio of 3:6:1, correspondingly, afterwards the obtained solution is optionally filtered. For complex obtaining in solid form the earlier obtained solution is concentrated, and then the crystallized product is separated and dried.
