| titleOfInvention | Preparation method of directing agent and preparation method of magnesium aluminum hydrotalcite |
| abstract | The invention discloses a preparation method of a directing agent and a preparation method of magnesium-aluminum hydrotalcite. The preparation method of the directing agent comprises: preparing a carbon source, a magnesium salt and an aluminum salt into a mixed solution, adjusting the pH of the solution to alkaline, and carrying out reaction to obtain a first mixed solution; the mass ratio of C in the carbon source to Mg in the magnesium salt and Al in the aluminum salt is 0.13-0.31:1.33-2.67:1; the first mixed solution is The solution is crystallized at a temperature of 120-200° C. to obtain a directing agent. By controlling the molar ratio of carbon, aluminum and magnesium, a directing agent with a layered structure of magnesium-aluminum hydrotalcite is prepared, which can make the synthesis of magnesium-aluminum hydrotalcite not deviate from the target, the crystal form is well developed, the synthesis time is short, and the efficiency is high. , Simple operation, no pollution, and friendly to the environment. |
