| titleOfInvention | Purification device and method for ammonium bifluoride |
| abstract | The present disclosure provides a purification device and method for ammonium bifluoride, comprising: a heating bottle for placing the ammonium bifluoride to be purified; Ammonium bifluoride is subjected to sub-boiling distillation; the condensing bottle is located outside the heating jacket; the connecting elbow, the two ends of the connecting elbow are connected with the heating bottle and the condensing bottle respectively, and the connecting elbow has an ascending section at the part connected to the heating bottle. The part connected to the condensing bottle has a descending section, so that the ammonium bifluoride sub-boilingly distilled in the heating bottle flows into the condensing bottle through the ascending section and the descending section. The disclosed ammonium bifluoride purification device has simple structure, simple operation, low cost, and is easy to obtain ultra-high-purity ammonium bifluoride. |
