Zirconium sulphate, disulfatozirconicacid - References
| Introduction | Zirconium sulfate is a white crystalline powder or crystalline solid. Hygroscopic. When heated to 100 °c, it becomes one molecule of crystal water, and becomes anhydrous at 380 °c. Soluble in water (18 ° C water solubility of 52g/100g), ethanol-soluble, insoluble in hydrocarbons, aqueous solution of litmus acidic. Aqueous solution at room temperature for a long time after 4 ZrO2 -3SO3-15H2O precipitation, the more dilute the solution more easily precipitated. Low toxicity, the median lethal dose of 3500mg/kg (rats, by mouth), irritating. |
| Application | Zirconium sulfate is an intermediate product used in the preparation of other zirconium compounds and can also be sold as finished products for rubber, paper, tanning and other industries. |
| production process | There are many methods to produce Zirconium sulfate. The methods to produce Zirconium sulfate from zircon are:(1) zircon → alkali fusion → water washing → Sulfuric acid leaching → ammonia precipitation → washing in addition to sodium → Sulfuric acid dissolution → evaporation crystallization → recrystallization → Zirconium sulfate product;(2) zircon → alkali fusion → water washing → hydrochloric acid leaching → hydrolysis → Sulfuric acid dissolution → crystallization → Zirconium sulfate product. |
| preparation | The zircon sand was crushed into zircon sand fine powder with particle size less than 325 mesh, and the zircon sand fine powder and sulfuric acid were mixed at 0.5MPa, the reaction was carried out at 200 ℃ for 5H, in which the mass ratio of zircon sand to sulfuric acid was 1:5.5, and the concentration of sulfuric acid was 70%. After the reaction was completed, the reaction was cooled to below 100 ℃, water 5 times the mass of zircon sand is added for stirring and washing, and then the filtrate is filtered and collected. Oxalic acid is added to the filtrate for complexation, and the mass of oxalic acid is 3.5 times that of ferric oxide, the reaction temperature was 60 ° C. And the reaction time was 2H. The resulting solution was crystallized to obtain Zirconium sulfate. |
