  • Patent number: 7622422
    Abstract: A method of preparing an ionic conducting gel in solid form, known as ionogel. The method includes a step of mixing an ionic liquid with at least one molecular precursor containing at least one hydrolyzable group, if necessary in the presence of an acid, such as a carboxylic acid. The mixture is subsequently left to stand for one or more days until a gel is formed by polycondensation of the molecular precursor(s). The gel contains the aforementioned ionic liquid and can be set, in particular in transparent monolithic solid form.
    Type: Grant

  • Patent number: 7160836
    Abstract: The invention describes materials comprising organic groups containing sulphur and phosphorous bonded together by a hydrocarbon chain and bonded via phosphorous and oxygen atoms to a mineral oxide of an element M, said materials being characterized in that they comprise M-O-M? bonds, M?representing an element of a mineral oxide identical to or different from M, in that the ratio of the element M to the phosphorous is about 0.5: 1 to about 500:1 and in that each phosphorous atom of the phosphorous-containing groups forms at least one P—O-M bond and/or P—O-M? bond. The invention also describes a process for preparing such materials.

  • Patent number: 6958307
    Abstract: The present invention relates to a composition including an organic phosphorous-containing group bonded via an oxygen atom to a metal oxide of at least one element M. Generally, the composition is essentially amorphous, and includes an essentially monomolecular layer of an organic group directly bonded to the phosphorous atom. In addition, the composition is generally essentially free of any phosphate, phosphonate or phosphinate phase of the element M. Moreover, the composition has a ratio of the element M to phosphorous of about 15:1-200:1.

  • Publication number: 20020128150
    Abstract: The invention describes materials comprising organic groups containing sulphur and phosphorous bonded together by a hydrocarbon chain and bonded via phosphorous and oxygen atoms to a mineral oxide of an element M, said materials being characterized in that they comprise M—O—M′ bonds, M′ representing an element of a mineral oxide identical to or different from M, in that the ratio of the element M to the phosphorous is about 0.5: 1 to about 500:1 and in that each phosphorous atom of the phosphorous-containing groups forms at least one P—O—M bond and/or P—O—M′ bond. The invention also describes a process for preparing such materials.

  • Publication number: 20020023573
    Abstract: Essentially amorphous functionalized materials comprise an essentially monomolecular layer of organic phosphorous-containing groups bonded to a mineral oxide of an element M via an oxygen atom of said oxide to a phosphorous atom that is itself preferably bonded to a hydrocarbon chain substituted at a distance from the phosphorous atom by a sulfur-containing group or by a reactive group that can be transformed into a sulfur-containing group, said materials being essentially free of phosphate, phosphonate and phosphinate phases of said element M and the sulfate of said element M when the materials comprise a sulfur-containing group. A process for preparing functionalized materials brings a suspension in a liquid of at least one mineral oxide of at least one element M into contact with a solution in a solvent of at least one phosphorous-containing compound usually comprising, at a distance from the phosphorous atom, a sulfur-containing group connected to said phosphorous atom via a hydrocarbon chain.

  • Patent number: 5767216
    Abstract: The present invention relates to the synthesis of optionally alkoxylated polyorganosiloxane (POS) resins by non-hydrolytic condensation. The object is to provide a process which offers the possibility of controlling the crosslinking. This object, inter alia, is achieved by the process according to the invention, which makes provision for carrying out a non-hydrolytic condensation reaction between alkoxysilyl units (Mo1) and halogenosilyl units (Mo2), both of which are carried by identical or different silanes, in the presence of a catalyst of the Lewis acid type, said condensation reaction generating essentially .tbd.Si--O--Si.tbd. linkages and coproducts XR (X=halogen).
