    摘要: This patent describes an economical and environment-friendly continuous process for the synthesis of anionic clay-containing compositions. It involves reacting a slurry comprising aluminium trihydrate and/or its calcined form, 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.

    摘要: This patent describes economical and environment-friendly processes for the synthesis of anionic clays and anionic clay-like materials with acetate anions as the charge-balancing interlayer species. It involves combining a slurry of a gibbsite or its thermally treated form with a slurry or solution of a magnesium source and magnesium acetate. The product is not washed, needs no filtration and exists in a close to neutral pH condition. It can be spray dried directly to form microspheres or can be extruded to form shaped bodies. Because of the absence of foreign salts 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.

    摘要: This patent describes an economical and environment-friendly process for the synthesis of anionic clays with carbonate and/or hydroxide anions as the charge-balancing interlayer species. It involves reacting a slurry comprising an aluminium source and a magnesium source, the aluminium source comprising two types of aluminium-containing compounds, preferably aluminium trihydrate and/or thermally treated calcined aluminium trihydrate. 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.
