Procedure

A solution was prepared by dissolving 10.27 grams (0.30 moles) of Aldrich sodiumtetraphenylborate in 250 milliliters of distilled water. To this, while stirring, was added a solution of 2.36 grams (0.32 moles) of Fisher reagent grade potassium chloride dissolved in 100 milliliters of distilled water. The white precipitate that formed was stirred for 10 minutes and filtered. The precipitate was then washed with distilled water and filtered, followed by drying at 60° C. under vacuum for 24 hours. Total yield was 10.20 grams (0.28 moles) of the potassium salt of tetraphenylborate.
