Procedure
A mixture of 28 g of gelatin and 13.2 g of benzotriazole was dissolved in 3,000 ml of water, and the resulting solution was stirred while maintaining it at 40° C. A solution of 17 g of silver nitrate in 100 ml of water was added over 2 minutes, and the resulting emulsion was precipitated and freed of excess salts by controlling its pH. Then the emulsion was adjusted to pH 6.0 to thereby yield benzotriazole (yield, 400 g).
Workup
- customthe resulting emulsion was precipitated
