Abstract: The invention relates to a process for synthesis of lamellar solids based on silicates comprising: i) a mixing stage, during which a mixture that comprises an alkaline metal, a silica source, water and an organic structuring agent is prepared, and ii) a crystallization stage during which this mixture is kept under conditions allowing the formation of a crystalline solid. The organic structuring agent that is used in this process comprises an alcohol group and an amine group that are separated by a hydrocarbon chain.

Abstract: The invention concerns a crystalline solid, designated ITQ-31, which has the X ray diffraction diagram given below. Said solid has a chemical composition, expressed as the anhydrous base in terms of moles of oxide, defined by the general formula XO2: mYO2:pZ2O3:qR:sF, in which R represents an organic nitrogen-containing template, X represents one or more tetravalent elements other than germanium, Y represents germanium, Z represents at least one trivalent element and F is fluorine.

Abstract: The invention concerns a method for preparing a crystalline metalloaluminosilicate by direct synthesis using at least one source of aluminium and, as the source of silicon and as the source of at least one other metal M, at least one lamellar siliceous material containing metals in its framework. The invention also concerns the novel solids obtained, in particular solids with a given zeolitic structure containing particular metals in its zeolitic framework.
