Procedure

In an amount of 32.4 g of behenic acid, 9.9 g of arachidic acid and 5.6 g of stearic acid were dissolved in 945 mL of pure water at 90° C. Then, the solution was added with 98 mL of 1.5 mol/L sodium hydroxide aqueous solution with stirring at high speed. Subsequently, the solution was added with 0.93 mL of concentrated nitric acid, cooled to 55° C. and stirred for 30 minutes to obtain a sodium behenate solution.
