FIELD: chemistry.
SUBSTANCE: described is method of obtaining cyanoborates of alkali metals of general formula M+[B(CN)4]-, where M - potassium by action of alkali metal cyanide on potassium tetrafluoroborate in conditions of hard-phase reaction, their further transformation into salts, including cyanoborate anions and organic cations, said salts can be used as ion liquids.
EFFECT: creation of efficient method of obtaining alkali metal cyanoborates.
