Silver → Silver behenate

Participants

Reaction Steps

To a solution prepared by dissolving 30 g of ossein gelatin in 750 ml distilled water, a 2.94M silver nitrate solution was added to result in a silver electrical potential of 400 mV. To the resulting solution, 374 ml of the above-mentioned sodium behenate solution was added at a rate of 44.6 ml/minute at 78° C., employing a controlled double-jet method, at the same time, an aqueous 2.94M silver nitrate solution was added to maintain the silver electrical potential at 400 mV. During the addition, the added amounts of sodium behenate and silver nitrate were 0.092 mole and 0.101 mole, respectively. After the addition, stirring continued for another 30 minutes, and the resulting water-soluble salts were removed using ultrafiltration.
