Abstract

A process for preparing an organically modified layered double hydroxide comprising an organic anion as charge-balancing anion by (a) preparing an aqueous suspension or solution comprising a divalent metal ion source, a trivalent metal ion source, and water and (b) reacting said divalent metal ion source and said trivalent metal ion source in said aqueous suspension or solution to obtain a layered double hydroxide, wherein an organic acid and a nonionic surfactant are added to the aqueous suspension or solution before, during or after step (b), and wherein the amount of the nonionic surfactant is between 0.1 and 10 wt%, based on the total weight of organic acid and nonionic surfactant.
