Two series of hybrid organic–inorganic hydrotalcites containing Mg2+ and Al3+ in the brucite-like layers (Mg/Al molar ratios of 2:1, 3:1 and 4:1) and lactate (Lc) as counter-anion were synthesized by coprecipitation using Lc/Al molar ratios of 0:1 and 3:1 to prepare the starting solutions. All samples have been characterised by element chemical analysis, powder X-ray diffraction, FT-IR spectroscopy, thermal analysis and morphology analysis (specific surface area measurement, particle size analysis and transmission electron microscopy). Delamination of the synthesized samples after dispersion in water and ultrasound treatment was followed by X-ray diffraction. Delamination has been compared to that shown by samples containing Zn and Al in the brucite-like layers, and it has been found that, contrary to the Zn-containing samples, restacking takes place in all cases upon solvent evaporation.
