More Information
Summary:The invention relates to process for the preparation of an alkali metal cyanoborate of formula (1): M +[B(CN)4] - (1), where M is Li, Na, K, Rb or Cs, comprising reacting an alkali metal tetrafluoroborate M[BF4], where M = Li, Na, K, Rb or Cs with an alkali metal cyanide MCN, where M = Li, Na, K, Rb or Cs, in a solid-state reaction. The alkali metal cyanoborate may subsequently be used in the preparation of a salt of general formula Kt +[BF(CN)4] - where the organic cation Kt + is (see above formula) and R is defined in claim 16.
