Participants

Reaction Steps

In 3,000 ml of water were dissolved 28 g of gelatin and 13.2 g of benzotriazole. Keeping the resulting solution at 40° C. under stirring, 100 ml of an aqueous solution containing 17 g of silver nitrate was added to the solution over 2 minutes. The pH of the obtained emulsion was adjusted to precipitate the excess salt, and the excess salt was removed from the emulsion. The emulsion was then adjusted to pH 6.3 to obtain a benzotriazole silver emulsion. The yield of the emulsion was 400 g.
