摘要

Hydrophobised double-layer hydroxide compounds may be produced if double-layer hydroxide compounds of general formula (I): [M<(II)>1-xM<(III)>x(OH)2] Ax * n H2O, in which M<(II)> is a divalent metal cation, M<(III)> is a trivalent metal cation, A is an equivalent of a single and/or multi-basic inorganic acid, x is a number from 0.2 to 0.5 and n is a number from 0 to 10, are caused to react at high temperature and autogenous pressure with at least one carboxylic acid or its salt and the reaction product is then dried. The hydrophobised double-layer hydroxide compounds obtained by this process are suitable as catalysts for the alkoxylation of compounds with active hydrogen atoms or fatty acid esters.
