Procedure

87.6 Kg of behenic acid (tradename: Edenor C22-85R) manufactured by Henkel, 423 L of distilled water, 49.2 L of an aqueous NaOH solution having a concentration of 5 mol/L and 120 L of t-butyl alcohol were mixed and the mixture was stirred at 75° C. for one hour to react, thereby obtaining a sodium behenate solution. Separately, 206.2 L (pH 4.0) of an aqueous solution containing 40.4 kg of silver nitrate was prepared and kept at 10° C. A reactor containing 635 L of distilled water and 30 L of t-butyl alcohol and kept at 30° C. was charged with all the foregoing sodium behenate solution and all the foregoing aqueous silver nitrate solution at constant flow rates respectively over 93 minutes and 15 seconds and 90 minutes.
