1. A process for preparing metal alkoxides by means of transalcoholization, wherein
a lower metal alkoxide is fed via a side feed into a reactive distillation column comprising a top, a bottom, a rectifying section situated above the feed and a stripping section situated below the feed;
a higher alcohol is fed into the stripping section, the bottom and/or a bottoms circuit of the column;
a solution of a higher metal alkoxide in the higher alcohol is taken off at the bottom of the column and/or from the bottoms circuit; and
a vapor comprising lower alcohol is taken off at the top of the column, the vapor is at least partially condensed and a substream of the condensate is recycled to the top of the column as reflux;, wherein the higher alcohol has a higher boiling point than the lower alcohol.
