| titleOfInvention | Method for producing electronic-grade ammonium fluoride water solution |
| abstract | The invention relates to a method for producing electronic-grade ammonium fluoride water solution. The method comprises the steps of taking industrial liquid ammonia as a raw material, heating the raw material to release ammonia; adsorbing and removing organic gas impurity in the ammonia by using active carbon; obtaining high-purity ammonia by deoxidizing adsorption; absorbing the high-purity ammonia by high-purity hydrofluoric acid, and then obtaining the electronic product grade ammonium fluoride water solution. The obtained electronic-grade ammonium fluoride water solution has high purity and stable quality, and can be directly used for producing electronic products. The method of the invention for producing electronic-grade ammonium fluoride water solution has a simple operation, and is suitable for continuously large-scale production. |
