  • Obtaining multimetallic oxides derived from hydrotalcite type compounds
    Patent number: 8211395
    Abstract: A procedure for obtaining mixed multimetallic oxides derived from hydrotalcite type compounds, characterized in that the laminar metallic hydroxides obtained are constituted by three or four metallic cations, forming part of the sheets of the hydrotalcite type material represented by the formula: [M(II)1?x?y?zM(II)?xM(III)yM(III)?z(OH)2](An?y+z/n).mH2O. by a process comprising: (1) preparing an aqueous or organic solution containing three or more cations; (2) preparing an alkaline solution; (3) slowly combining solutions (1) and (2) to cause the co-precipitation of the cations in the form of hydroxides; (4) washing the precipitate containing the hydrotalcites with water, until removal of the non-precipitated ions; (5) drying; and (6) calcining the hydrotalcites.
    Type: Grant
