Procedure

Added to 945 ml of pure water were 32.4 g of behenic acid, 9.9 g of arachidinic acid, and 5.6 g of stearic acid, mixed, and stirred at 90° C. Subsequently, while stirring the resulting mixture at a high speed, 98 ml of a 1.5N aqueous sodium hydroxide solution was added. After adding 0.93 ml of concentrated nitric acid, the resulting mixture was cooled to 55° C. and stirred for 30 minutes to obtain a sodium behenate solution.
