Abstract

A process for producing high-purity hydrotalcites by reacting alcohols or alcohol mixtures with at least one or more divalent metal(s) and at least one or more trivalent metal(s) and hydrolyzing the resultant alcoholate mixture with water. The corresponding metal oxides can be produced by calcination.
