METHOD OF PRODUCING MAGNETOACTIVE COMPOUND Russian patent published in 2017 - IPC C01G49/00 H01F1/44

Abstract RU 2634026 C1

FIELD: chemistry.

SUBSTANCE: method of producing a solution of a magnetoactive compound involves condensation from a solution of iron sulphate (II) containing lignosulfonates and an oxidant solution when mixed. An aqueous ammonia solution of silver nitrate with the addition of tetraethylammonium hydroxide is used as an oxidizing agent.

EFFECT: simplifying the synthesis of a magnetoactive compound and its production in the form of a stable aqueous solution.
