| titleOfInvention | Preparation method of nano solid strong base catalytic material K2[ (OH) F4B3O3] |
| abstract | The invention relates to the field of nano material preparation, and aims to provide a nano solid strong base catalytic material K 2 [(OH)F 4 B 3 O 3 ]The preparation method of (1). The method comprises the following steps: stirring and mixing potassium fluoride, boric acid, potassium fluoborate, potassium tetraborate and deionized water, adding OP-10, cetyl alcohol and liquid paraffin, mixing and emulsifying; adding the mixture into a hydrothermal kettle, heating to 110-120 ℃, and carrying out hydrothermal treatment; carrying out hydrothermal treatment to obtain an emulsified mixed solution; demulsifying, centrifugally separating, cleaning and drying the obtained powder to obtain the nano solid strong alkali catalytic material. The product of the invention is a composite oxide material, has higher alkali strength, extremely low water solubility and F ionized in water ‑ The concentration is extremely low, and the environmental water body is not easy to be polluted. Therefore, the KF/Al is better replaced 2 O 3 The environment-friendly catalytic material. Can realize the high-efficiency catalysis of the Michelal addition reaction, and the yield of the product can reach more than 90 percent. The method can also be applied to the fields of brazing, heat insulation, metal corrosion prevention and the like, and has good application prospect in other industrial fields. |
