    摘要: The present invention provides a dye loaded zeolite material comprising: a) at least one zeolite crystal having straight through uniform channels each having a channel axis parallel to, and a channel width transverse to, a c-axis of crystal unit cells; b) closure molecules having an elongated shape and consisting of a head moiety and a tail moiety, the tail moiety having a longitudinal extension of more than a dimension of the crystal unit cells along the c-axis and the head moiety having a lateral extension that is larger than said channel width and will prevent said head moiety from penetrating into a channel; c) a channel being terminated, in generally plug-like manner, at least at one end thereof located at a surface of the zeolite crystal by a closure molecule hose tail moiety penetrates into said chanel and whose head moiety substantially occludes said channel end while projecting over said surface; and d) an essentially linear arrangement of luminescent dye molecules enclosed within a terminated channel adjacent to at least one closure molecule and exhibiting properties related to supramolecular organization.

    摘要: L'invention concerne une solution aqueuse ayant un pH supérieur à 5, de préférence d'au moins 6.5, utilisable dans un procédé d'échange ions, en particulier un procédé de fabrication de zéolite. Cette solution aqueuse contient des cations métalliques, tel le zinc, et un agent complexant desdits cations métalliques, tel l'acide citrique ou un sel de cet acide. La proportion de cations libres en solution représente de 0.1 % à 99 %, de préférence de 1 à 30%, de la quantité totale dudit métal dans la solution. L'invention porte aussi sur un procédé de fabrication de zéolites X ou A mettant en oeuvre une telle solution aqueuse et l'utilisation des zéolites ainsi obtenues pour séparer, purifier ou convertir un ou des constituants d'un flux gazeux, tels l'air, les gaz de synthèse ou les hydrocarbures, notamment les oléfines, par mise en ouvre d'un procédé d'adsorption, notamment de type PSA, VSA ou TSA.

    摘要: The formation of new materials in the form of alumino-silicate derivatives from 2:1 layer clay materials which are obtained by the chemical modification of 2:1 layer clay minerals by reaction with a salt having the formula MX wherein M is ammonium ion or alkali metal cation and X is a halide. The new materials have the following characteristics: (a) an amorphous x-ray diffraction signal manifest as a broad hump using x-ray powder diffraction between 22° and 32° 2theta using CuKalpha radiation; and (b) the presence of primarily tetrahedrally coordinated aluminum.
