FIELD: chemistry.
SUBSTANCE: invention can be used for obtaining solutions of lithium ferrocyanide, which is applied in synthesis of normal ferrocyanides of transition metals (Cu2+, Ni2+, Co2+, Zn2+, Fe3+, etc.) of general formula Me2[Fe(CN)6]. Method of obtaining solution of lithium ferrocyanide consists in application of strongly acidic cationite, which is transferred from H+-form into Li+-form, after which, solution of ferrocyanide of alkali metal is passed through it. Cationite KY-2-8 in H+-form is used as strongly acidic cationite.
EFFECT: invention makes it possible to obtain pure solutions of lithium ferrocyanide of various concentrations, simplify technology and reduce time of finished product obtaining.
