MODIFICATION OF LAYERED DOUBLE HYDROXIDES |
摘要 |
Disclosed herein is a process for modifying a layered double hydroxide (LDH), the process comprising a. providing a material comprising a layered double hydroxide of formula: [Mz+1-xM′y+x(OH)2]q+(Xn−)q/n.bH2O wherein M and M′ are metal cations, z is 1 or 2, x is 0.1 to 1, b is 0 to 5, y is 3 or 4, X is an anion, n is 1 to 3 and q is determined by x, y and z; b. optionally washing the material at least once with a mixture of water and a mixing solvent miscible with water; and c. washing the material obtained in a. or b. at least once with at least one first solvent, the first—solvent being miscible with water and having a solvent polarity P′ in the range of 3.8 to 9 to obtain a modified layered double hydroxide. |

1. A process for modifying a layered double hydroxide (LDH), the process comprising,
a. providing a material comprising a layered double hydroxide of formula:
[Mz+1-xM′y+x(OH)2]q+(Xn−)q/n.bH2Owherein M and M′ are metal cations, z is 1 or 2, x is 0.1 to 1, b is 0 to 5, y is 3 or 4, X is an anion, n is 1 to 3 and q is determined by x, y and z, b. optionally washing the material at least once with a mixture of water and a mixing solvent miscible with water, and c. washing the material obtained in step a or b at least once with at least one first solvent, the first solvent being miscible with water and having a solvent polarity P′ in the range of 3.8 to 9 to obtain a modified layered double hydroxide. |
