<P>PROBLEM TO BE SOLVED: To provide a method for efficiently producing a tetracyanoborate compound (VI). <P>SOLUTION: A boron compound (for example, boron trichloride) and an ammonium derivative having a halogenide ion as a counter anion are mixed in xylol; then, a trialkylsilyl cyanide is added and reacted; the reaction system is subjected to a treatment with hydrogen peroxide, and an extraction treatment with butyl acetate; and butyl acetate is distilled out to obtain a tetracyanoborate compound represented by formula (VI) wherein [Kt]m+ is an ammonium cation; and m=1. In the formula, [Kt]m+ denotes an organic cation or an inorganic cation; and m denotes an integer of 1 to 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
