実験手順
88 kg of the recrystallized behenic acid, 422 L of distilled water, 49.2 L of a 5 mole/L sodium hydroxide aqueous solution and 120 L of t-butyl alcohol were mixed and reacted by stirring at 75° C. for 1 hour to obtain sodium behenate solution B. Separately, 206.2 L of an aqueous solution of 40.4 kg of silver nitrate (pH 4.0) was prepared and maintained at 10° C. A reaction vessel charged with 635 L of distilled water and 30 L of t-butyl alcohol was maintained at 30° C., and the sodium behenate solution and the silver nitrate aqueous solution were entirely added thereto under sufficiently stirring at constant flow rates over 93 minutes and 15 seconds and 90 minutes, respectively. At this time, only the silver nitrate aqueous solution was added in the duration for 11 minutes after starting the addition of the silver nitrate aqueous solution. Thereafter, the addition of the sodium behenate solution was started, and only the sodium behenate solution was added in the duration for 14 minutes and 15 seconds after completing the addition of the silver nitrate aqueous solution. The temperature inside the reaction vessel at this time was 30° C., and the outer temperature was controlled to maintain the liquid temperature constant. The piping of the addition system for the sodium behenate solution was kept temperature by circulating warm water in the outer space of the double pipe, so as to adjust the liquid temperature at the outlet of the addition nozzle to 75° C. The piping of the addition system for the silver nitrate aqueous solution was kept temperature by circulating cold water in the outer space of the double pipe. The addition position of the sodium behenate solution and the addition position of the sodium nitrate aqueous solution were symmetrically disposed with respect to the stirring axis, and were prevented from being in contact with the reaction solution by adjusting the heights thereof.
