| titleOfInvention | A kind of preparation method of high-purity indium acetate crystal |
| abstract | The present invention relates to a preparation method of high-purity indium acetate, which comprises the following steps: S1, material preparation: prepare materials according to a certain proportion of indium hydroxide powder, glacial acetic acid and pure water; add glacial acetic acid with a purity of more than 99.5% to pure water , then stir and disperse to form the first mixed solution; S2, dissolve: after heating the first mixed solution to a constant temperature, add indium hydroxide powder with a purity of 99.99% to the first mixed solution at a certain rate, indium hydroxide After the powder is added, the second mixed solution is formed; the second mixed solution is condensed and refluxed for a certain period of time under normal pressure conditions, and after the reaction is complete, water is added to the second mixed solution and stirred until the second mixed solution is completely clear, and the second mixed solution is obtained. Three mixtures; S3, purification: add hydrogen peroxide at a certain rate to the third mixture, keep the pH of the third mixture constant for a certain period of time, filter the precipitate, and obtain a colorless and transparent indium acetate solution with a certain concentration; S4, crystallization: Crystallization in the evaporator. |
