Versuchsvorschrift
Water (20 L) was added to cetyl phosphate (molar ratio of diester/monoester=1/1; acid value, 194 mg KOH/g) (1 kg) while heating at 70° C., whereby the cetyl phosphate was dispersed uniformly. An aqueous solution of sodium hydroxide (500 g/L) (278 ml) was dropwise added to the mixture while keeping the said temperature. When the addition was finished, the mixture showed a pH of about 11. Further, stirring was continued at 70° C. for 60 minutes. An aqueous solution of barium chloride (200 g/L) (1825 ml) was gradually added thereto at a temperature of 70 to 80° C. After the addition was finished, the mixture was stirred at about 70° C. for 30 minutes. On confirming that the remaining barium ion became constant, the reaction was finished. The product was collected, washed with water, filtered, dried at 70° C. for 76 hours and pulverized in a mortar to give barium cetyl phosphate (1154 g). Yield, 93.5%. M.P., 174 to 183° C. Apparent specific volume, 3.6 ml/g. Elementary analysis: calcd., P=5.8%, Ba=19.2%; found, P=5.9%, Ba=18.0%.
