The present invention relates to a method for modifying a layered double hydroxide (LDH) comprising the following steps and a layered double hydroxide prepared according to the method: (a) water-soaked in water of formula (1) of) a / r ยท b H 2 O (1) ( formula, M and - [M z + 1- x M 'y + x (OH) 2] a + (x n: wet) layered double providing a hydroxide M'is a metal cation, z = 1 or 2, y = 3 or 4, x is 0.1 to 1, preferably x <1, more preferably x = 0.1 to 0.9, b is 0 To 10, X is an anion, r is 1 to 3, n is the charge on the anion X, a is determined by x, y and z, preferably a = z(1-x)+xy- 2); (b) maintaining the layered double hydroxide wet with water; And (c) contacting the layered double hydroxide wetted with water with at least one solvent (the solvent is miscible with water, preferably having a solvent polarity (P') in the range of 3.8 to 9). |
