Coprecipitation of Mg~(2+) and Al~(3+) with N-tetradecylglycin at reasonable pH resulted in the formation of pillared hydrotalcite (N-LDH) where the N-tetradecylglycin anion occupied the interlayer space.

Succinate, adipate, dodecyl sulfonate, benzoate, p-hydroxybenzoate and terephthalate-pillared hydrotalcites have been successfully synthesized by direct reaction of the free acid with Mg4Al2(OH)12CO3.

Terephthalate pillared hydrotalcites, Mg 4Al 2(OH) 12 [C 6H 4(COO) 2] , were successfully synthesized through Mg 4Al 2(OH) 12 CO 3·4H 2O precursor in an organic solvent by ion exchange.

Zn-Al layered double hydroxides were prepared with Co-precipitation methods;The tartaric acid column pillared hydrotalcites were synthesized by direct reaction of the tartaric acid with Zn-Al-CO2-3precursor layered double hydroxides(LDHs).

The optical pure tartaric acid-pillared hydrotalcites were synthesized by direct reaction of the optical pure tartaric acid with Mg_4Al_2(OH)_(12)CO_3.

The maleic acid anions column pillared hydrotalcites were synthesized.

An auxiliary PVC thermal stabilizer, stearic acid pillared hydrotalcite, was prepared using anion-exchanged method.
