PROCESS FOR THE PREPARATION OF CARBOXYLATES OF RARE-EARTH ELEMENTS |
| 摘要 |
A proposed process provides the possibility for the preparation of carboxylates of REE in pure form with high yield. A process comprises the interaction of carboxylic acid with already produced amorphous hydroxide of rare-earth element (III) in medium of dry toluene at a temperature of 75-85 °C with simultaneous separation of water. |
