実験手順

In the preparation of Types I & II silver stearate, solution A was first prepared by adding 0.15 moles of solid sodium hydroxide to a dispersion of 0.1575 moles and 0.176 moles of stearic acid in 1 L of deionized water at 75° C. thereby producing a solution of sodium stearate with a pH of ca. 9. Solution B, 250 mL of 0.6M aqueous silver nitrate acidified with 0.4 g of 65% nitric acid at a temperature of 65° C., was then added with vigorous stirring to solution A in 15s while maintaining a temperature of 75° C. After 1 minute the resulting suspension of silver stearate was cooled to room temperature and had a pH of ca. 5 and a UAg of ca. 310 mV. The silver stearate was filtered off under reduced pressure, washed twice each time with about 5 L of deionized water and dried in a forced air drying cupboard at 40° C.
