Benzoic Acid → Potassium Benzoate

In a separate run, a mixture of 61 g (0.5 mole) benzoic acid and 34.6 g (0.52 mole) potassium hydroxide in 146 g of distilled water was stirred at 80°-85° C. under a stream of air until 115 g of water had evaporated. The resulting mixture was cooled to yield solid potassium benzoate which contained 34 weight percent water based on the total material weight. A portion of the solid was removed for slurry viscosity measurement, and the rest of the solid was filtered to remove excess water. The filtered solid contained about 23 weight percent water based on the total material weight. Separate slurries of the wet KBz solid, and of the filtered KBz solid in terphenyl were prepared at 150° C. The slurry viscosities at 200° C. were 225 centipoise for the wet solid and 14.8 centipoise for the filtered solid.
