実験手順

Water (88 L) was added to stearyl phosphate (molar ratio of diester/monoester=1/2.7; acid value, 232 mg KOH/g) (5 kg) while heating at 90° C., whereby the stearyl phosphate was dispersed uniformly. An aqueous solution of potassium hydroxide (300 g/L) (3862 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. The saponified dispersion was divided in five equal parts, and an aqueous solution of zinc sulfate (300 g/L) (1591 ml) was added to each part at 50°, 60°, 70°, 80° or 90° C. and the mixture was further stirred for 90 minutes. The product was collected, washed with water, filtered, dried at 75° C. for 72 hours and pulverized by the aid of a water-cooling type hammer mill to give zinc stearyl phosphate. The results are shown in Table 1.
