With sodium hydroxide; In water; at 45 - 65℃; for 10h;
Tolyltriazole (26.63 g. 200 mmol) and 3-chloro-2-hydroxy-l-propanesulfonic acid sodium salt hydrate (43.25 g, 220 mmol) are dissolved in 160 mL of distilled water at room temperature. To the stirred solution is added 16.0 g of 50% aqueous sodium hydroxide solution dropwise, and the solution is heated to 45 C for four hours and then held at 65 C for six hours. The solution is allowed to cool to room temperature and 137 g of distilled water is added. The solution is determined to be 25.45% solids.
