Title (EN) SIMPLIFIED SYNTHESIS OF ANION INTERCALATED HYDROTALCITES
(FR) SYNTHESE SIMPLIFIEE D'HYDROTALCITES A ANIONS INTERCALES
Abstract:
(EN) The present invention is one-step method for synthesizing a synthetic anion intercalated hydrotalcite material. The method comprises reacting an aluminum source with a magnesium source in the presence of an inorganic acid of the anion to be intercalated, and in the absence of a Group IA metal source. The resulting slurry can be dried to form the final product.
(FR) L'invention porte sur un procédé en une étape de synthétisation d'un matériau du type hydrotalcite à anion synthétique intercalé. Ledit procédé consiste à faire réagir une source d'aluminium avec une source de magnésium en présence d'un acide inorganique de l'anion à intercaler et en l'absence d'une source de métal du groupe IA. La boue résultante une fois séchée donne le produit final.
