Procedure
While stirring 876 g of behenic acid (Edenor C22-85R, product of Henkel Corporation), 4,230 ml of distilled water and 1,200 ml of tert-butanol at 75° C., added over 5 minutes was 492 ml of a 5N aqueous NaOH solution, and then reacted for 60 minutes to obtain sodium behenate solution. Independently, 2,062 ml of aqueous solution containing 404 g of silver nitrate (pH 4.0) was prepared and kept at 10° C. A reaction vessel containing 6,350 ml of distilled water and 300 ml of tert-butanol was kept at 30° C., and an entire volume of the aqueous silver nitrate solution was added at a constant flow rate over 60 minutes, and 7 minutes after, an entire volume of the sodium behenate solution was added at a constant flow rate over 62 minutes (the last 9-minute period was dedicated to the single addition of the sodium behenate solution). The mixture was allowed to stand for 20 minutes under stirring, and then cooled to 25° C. The solid content was separated by suction filtration, and then washed with water until electric conductivity of the filtered water decreased as low as 30 μS/cm. The obtained solid content was stored in a form of a wet cake without drying.
