Abstract
An economical and environment-friendly processes for the synthesis of anionic clays and the products made therefrom. It involves reacting a slurry comprising non-peptized boehmite with a magnesium source. There is no necessity to wash or filter the product. It can be spray dried directly to form microspheres or can be extruded to form shaped bodies. The product can be combined with other ingredients in the manufacture of catalysts, absorbents, pharmaceuticals, cosmetics, detergents, and other commodity products that contain anionic clays.
