METHOD OF PRODUCING MAGNETOACTIVE COMPOUND Russian patent published in 2012 - IPC C01G49/08 H01F1/28

Abstract RU 2453500 C1

FIELD: chemistry.

SUBSTANCE: to obtain a magnetoactive compound, ligosulphonates first undergo nitrosation with sodium nitrite in an acidic medium and the magnetoactive compound is then deposited in the presence thereof. During nitrosation, the acidic medium is formed by adding an acid, preferably nitric acid.

EFFECT: invention increases magnetic susceptibility of the magnetoactive compound.
