反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: then adding a quantity of sodium hydroxide as a 2M aqueous solution (for quantity see table 7) at the same temperature as the palmitic acid dispersion with stirring over a particular time (see table 7 for the time of addition) thereby producing a clear solution with a pH of about 9.2 substantially containing sodium palmitate; for the time of addition)

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: In the preparation of Types I & II silver palmitate 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 palmitic acid respectively in 1 L of deionized water at 68° C. thereby producing a solution of sodium palmitate 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 58° C., was then added with vigorous stirring to solution A in 15 s while maintaining a temperature of 68° C. After 1 minute the resulting suspension of silver palmitate was cooled to room temperature and had a pH of ca. 5 and a UAg of ca. 350 mV. The silver palmitate 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. A was first prepared
