Title (EN) SILVER-DECORATED METAL-ORGANIC FRAMEWORK FOR OLEFIN/ALKANE SEPARATION
(FR) STRUCTURE ORGANOMÉTALLIQUE DÉCORÉE D'ARGENT POUR SÉPARATION D'OLÉFINE/ALCANE
Abstract:
(EN) There is provided a porous metal-organic framework comprising a Hafnium or Zirconium metal; an aromatic compound substituted with at least one carboxylate and optionally with at least one functional group selected from F, CF3, NH2, NO2, O-, S-, COO-, SO2- and PO3-; and a silver cation complexed to the aromatic compound. There is also provided a method for preparing a porous metal-organic framework as defined above, comprising i) dissolving an aromatic compound, substituted with at least one carboxylate and optionally at least one functional group selected from F, CF3, NH2, NO2, O-, S-, COO-, SO2- and PO3-, and a zirconium or hafnium salt in a solvent mixture of water and an organic acid, heating the solution to a temperature of 50-200ºC for 12-60 h to obtain a solid, ii) suspending the obtained solid and a silver salt in a solvent mixture of water and an organic solvent. There is also provided a process for separating an olefin from an alkane comprising placing a porous metal-organic framework as defined above into a container and purging the container with a mixture of an olefin and an alkane, wherein the olefin is preferentially retained within the porous metal-organic framework.
(FR) L'invention concerne une structure organométallique poreuse comprenant un métal de zirconium ou hafnium ; un composé aromatique substitué par au moins un carboxylate et éventuellement par au moins un groupe fonctionnel choisi parmi F, CF3, NH2, NO2, O-, S-, COO-, SO2 - et PO3 - ; et un cation d'argent complexé au composé aromatique. L'invention concerne également un procédé de préparation d'une structure organométallique poreuse telle que définie ci-dessus, consistant à : i) dissoudre un composé aromatique, substitué par au moins un carboxylate et éventuellement au moins un groupe fonctionnel choisi parmi F, CF3, NH2, NO2, O-, S-, COO-, SO2 - et PO3 -, et un sel de zirconium ou hafnium dans un mélange de solvants d'eau et d'un acide organique, à chauffer la solution à une température entre 50 et 200 °C pendant 12 à 60 heures pour obtenir un solide, ii) à mettre en suspension le solide obtenu et un sel d'argent dans un mélange de solvants d'eau et d'un solvant organique. L'invention concerne également un procédé de séparation d'une oléfine et d'un alcane, le procédé consistant à placer une structure organométallique poreuse telle que définie ci-dessus dans un récipient et à purger le récipient avec un mélange d'une oléfine et d'un alcane, l'oléfine étant de préférence retenue dans la structure organométallique poreuse.
