| Abstract: | A new method of manufacturing potassium sulfate by solvent extraction has been studied. The result indicates that isopentol is more selective in extracting hydrochloric acid. At room temperature, when trioctylamine (0.5 mol/L) isopentol is used as mixed extracting agent, the conversion per pass can be up to 88.64%, and the purity of potassium sulfate is very high, impurity of chloride is as low as 0.18%, which coincides with the National Standards. |
