| titleOfInvention | Process for the preparation of a catalyst from clays for the hydration of olefins and the so prepared catalyst |
| abstract | Process for the preparation of a catalyst from clay minerals for the hydration of olefins with 2-3 C atoms to the corresponding alcohols from phosphoric acid and carrier material, whereby an essentially montmorillonite containing clay, with no more than 3% accompanying minerals such as quartz, feldspar and Mica, is contaminated and can contain up to 0.5% K 2 0, first treated with acid in a first stage until it has an Al 2 O 3 content of 13-18% by weight and, if appropriate, by adding precipitated alumina a surface area of 200 -400 m 2 / g, preferably 240 - 300 m 2 / g, comprising, after 5 to 15% by weight, based on the Gesamttrokkensubstanz, of one or more oxides of metals of VI.. Subgroup of the periodic table is added, then molded at a total water content of 20-35% by pressing, calcined at 500 - 800 ° C and then the shaped support material is treated in a second stage with acid until it has an Al 2 O 3 content of . 1-5 wt%, preferably 1 -. 3% by weight, and a surface area of 150- 250 m 2 / g, preferably, 180 - 220m 2 / g, and in impregnating the support thus obtained in a known manner with phosphoric acid.n n n Other minerals from the montmorillonite group which do not contain potassium but contain the montmorillonite crystal lattice can also be used. Furthermore, you can also start from an acid-treated bleaching earth. |
