Title (EN) PROCESS FOR PRODUCING ANION-LAYERED DOUBLE HYDROXIDE INTERCALATION COMPOUNDS AND PRODUCTS THUS PRODUCED
(FR) PROCEDE DE FABRICATION DE COMPOSES INTERCALES D'HYDROXYDE DOUBLE STRATIFIES ANIONIQUES ET PRODUITS AINSI FABRIQUES
Abstract: front page image
(EN)A process for producing anion-layered double hydroxide intercalation compounds wherein a metal hydroxide is used as the starting material of a layered double hydroxide (LDH) as the host substance and an anion compound even having a sterically complicated and large-sized structure is usable as the guest substance. This process is characterized in that the product of the reaction between the metal hydroxide and the anion compound is subjected to a hydrothermal reaction by heating in the absence of any anion component other than the anion compound employed as the guest substance. Anion-layered double hydroxide intercalation compounds containing bile acid as the anion compound serving as the guest substance which are useful as drug carriers, adsorbents for physiologically active substances, etc.
(FR)L'invention concerne un procédé de fabrication de composés intercalés d'hydroxyde double stratifiés anioniques. L'hydroxyde métallique sert de matériau d'amorçage d'un hydroxyde double stratifié (LDH) en tant que substance hôte et on peut utiliser comme substance invitée un composé anionique présentant même une structure de grande dimension et stériquement complexe. Ce procédé se caractérise en ce que le produit de la réaction entre l'hydroxyde métallique et le composé anionique est soumis à une réaction hydrothermique par chauffage en l'absence de tout élément anionique autre que le composé anionique utilisé comme substance invitée. Des composés intercalés d'hydroxyde double stratifiés anioniques contiennent de l'acide biliaire en tant que composé anionique servant de substance invitée sont utiles en tant que vecteurs de médicaments, d'adsorbants pour des substances physiologiquement actives, etc.
