Participants

Reaction Steps

The mixture thus obtained was stirred for 5 minutes, and mixed with a solution of 3.4 g of benzotriazole and 1.2 g of sodium hydroxide in 150 ml of water and a solution of 5 g of silver nitrate in 150 ml of water simultaneously over 6 minutes, to prepare an emulsion. “DEMOL N” manufactured by Kao Corporation was added to the emulsion to control its pH, to precipitate the emulsion and remove excess salts. The pH of the emulsion was then controlled to 6.0 to prepare a silver benzotriazole emulsion with a yield of 476 g.
