POLYTYPE MG-AI HYDROTALCITE

摘要

The present invention pertains to Mg-Al anionic clay having 3R2 stacking. Thisnew polytype of anionic clay has a three-layer repeat, but it has a differentinterlayer arrangement than the conventional 3R1, hydrotalcite. Said newpolytype can be applied in all applications described before for theconventional 3R1 polytype anionic clay such as in catalyst compositions,catalyst additive compositions, catalyst supports, absorbent compositions,stabiliser compositions and in medicaments.
