Sodium Hydroxide → HCID 178440700, compound

1.0 g of 5-butylbenzotriazole, 0.24 g of sodium hydroxide, and 25 g of phthalated gelatin were dissolved in 700 mL of water. The solution was kept at 60° C. and stirred. Then, to the resulting solution were added a solution prepared by dissolving 5 g of 5-butylbenzotriazole and 1.2 g of sodium hydroxide in 150 mL of water and a solution prepared by dissolving 5 g of silver nitrate in 150 mL of water, simultaneously, over a period of 4 minutes. The resulting solution was stirred for 5 minutes. After that, to the solution were added a solution prepared by dissolving 5 g of 5-butylbenzotriazole and 1.2 g of sodium hydroxide in 150 mL of water and a solution prepared by dissolving 5 g of silver nitrate in 150 mL of water, simultaneously, over a period of 6 minutes. The pH of the resulting emulsion was adjusted so as to cause precipitation and excess salt was removed. After that, the pH was adjusted to 6.0, and a silver 5-butylbenzotriazole emulsion in an yield of 470 g was obtained.
