BASIC IRON (III) ACETATE PRODUCING METHOD Russian patent published in 2008 - IPC C07C53/10 C07F15/02 

FIELD: salts of iron and organic acid producing processes, namely production of salt of iron (III) and acetic acid.

SUBSTANCE: method is realized by relation of metallic iron with acetic acid at presence of oxidizing agent; using molecular iodine, iron oxides such as Fe₂O_3, Fe₃O₄ and oxygen of air as oxidizing agent for converting impurity of iron (II) acetate to basic iron (III) acetate. Process is performed in beads mill at temperature 80°C_{and at mass relation of liquid charge and glass beads 1 : 1. Iron is used in the form of shell abutted to lateral surface of reactor housing. Initial molar relation of iron oxide and iodine is 10 : 1. Molar relation of acetic acid, its anhydride and iron oxide is in range 100 : (2 - 5.99) : (2 - 2.5). In time moment of practically complete consumption of iron oxide, solid phase of reaction mixture is taken off by filtering. Simultaneously consumed reagents are replenished and filtrate is returned to reactor for repeating process. Number of processes to be repeated is no more than 5. At second stage residues of iron (II) salt are after-oxidized to basic iron (III) acetate due to drying up taken off solid phase of product in filter by means of blowing air at environmental temperature. Preferably, hematite, γ-oxide or minimum is used as Fe2 O 3 and magnetite and Fe3O4 x 4H2Ois used asFe3 O4.}

EFFECT: simplified process, usage of available reagents.
