Title (EN) METHOD FOR PREPARING MESOPOROUS SILICA
(FR) PROCÉDÉ DE PRÉPARATION DE SILICE MÉSOPOREUSE
Abstract:
(EN) A method for preparing mesoporous silica from a hybrid silica/alkylene polyoxide material, comprising the extraction of the organic agents used in the preparation of the hybrid silica/alkylene polyoxide material by means of a treatment with supercritical CO2.
(FR) Procédé de préparation de silice mésoporeuse à partir d'un matériau hybride silice/ polyoxyde d'alkylène, ce procédé comprenant l'extraction des agents organiques utilisés dans la préparation du matériau hybride silice/ polyoxyde d'alkylène au moyen d'un traitement par CO2 supercritique.
