| Abstract: | Volatile amines are used in boiler-water treatment and their performance is judged not only from two main factors, viz., basicity and volatility, but also from their thermodynamic stability, metal complexation capacity and interaction with ion-exchange systems. The complexation of copper by 1-dimethylaminopropan-2-ol was studied. Its pKb value was found to be 4.5 at 25°C. It formed a coloured complex in the pH range 8.5–10.5 and its log K value was found to be 18.2. |
