<p>PCT No. PCT/EP91/01993 Sec. 371 Date Apr. 29, 1993 Sec. 102(e) Date Apr. 29, 1993 PCT Filed Oct. 21, 1991 PCT Pub. No. WO92/07795 PCT Pub. Date Mar. 5, 1992.Novel hydrophobicized double-layer hydroxide compounds, processes for their production by reaction of double-layer hydroxides with aliphatic mono- and/or dicarboxylic acids, and their uses as alkoxylation catalysts for compounds containing active H atoms or for fatty acid esters. The hydrophobicized double-layer hydroxide compounds correspond to formula (I) (M(II)1-xM(III)x(OH)2)Aa Bb * z H2O (I) in which M(II) is a divalent metal cation selected from the group consisting of magnesium, zinc, calcium, iron, cobalt, copper, cadmium, nickel and manganese; M(III) is a trivalent metal cation selected from the group consisting of aluminum, iron, chromium, manganese, bismuth and cerium; A is an equivalent of a monoanion of an aliphatic C2-34 monocarboxylic acid or an equivalent of a dianion of an aliphatic C4-44 dicarboxylic acid; B is an anion selected from the group consisting of carbonate, hydrogen carbonate, sulfate, nitrate, nitrite, phosphate, hydroxide, and halide; and wherein 0.1</=x</=0.5 0<a</=0.5 0</=b</=0.5 0<a+b</=0.5 0</=z</=10; but excluding compounds containing the combinations of magnesium and aluminum with carbonate and/or sulfate.</p> |
