Procedure
The following were mixed: 87.6 kg of behenic acid (trade name; Edenor c22-85R) made by Henckel Co., 423 L of distilled water, 49.2 L of an 5 mol/L aqueous NaOH solution, and 120 L of tert-butanol. The mixture was stirred at 75° C. for 1 hour to advance reaction. In this way, a sodium behenate solution was yielded. Separately, 206.2 L (pH: 4.0) of an aqueous solution of 40.4 kg silver nitrate was prepared, and the temperature of the solution was kept at 10° C. A reaction container in which 635 L of distilled water and 30 L of tert-butanol were put was kept at 30° C. While the solution was sufficiently stirred, thereto were added all amount of the sodium behenate solution and all amount of the aqueous silver nitrate solution at constant flow rates over 93 minutes 15 seconds and 90 minutes, respectively. In this case, for 11 minutes after the start of the addition of the aqueous silver nitrate solution, only the aqueous silver nitrate solution was added. Thereafter, the addition of the sodium behenate solution was started. For 14 minutes 15 seconds after the end of the addition of the aqueous silver nitrate solution, only the sodium behenate solution was added. At this time, the temperature of the reaction container was set to 30° C., and external temperature was controlled to make the temperature of the solution constant. Laying pipes of the sodium behenate adding system were kept warm by circulating hot water to the outside of its double pipes, and the solution temperature of an outlet made at the tip of an adding nozzle was adjusted to 75° C. Laying piles of the adding system of the aqueous silver nitrate solution were kept cool by circulating cool water to the outside of its double pipes. Positions where the sodium behenate solution and the aqueous silver nitrate solution were added were set to be symmetrical around a stirring axis as a center. The positions were also adjusted not to contact the reaction solution.
