Abstract
The invention relates to a process for separating ketones from alcohols by chemical interaction. More specifically, a difference in chemical reactivity between ketones and alcohols with a third compound is used as a basis for the separation. The third compound in this case is an organo-metallic compound of the general formula M(X).sub.n. Herein is M a polyvalent metal atom, n equals the valence of the metal and X is an organic or inorganic group or atom, with the proviso that at least one organic group is present in the organo-metallic compounds according to the invention. If the ketone-alcohol mixture is subjected to the organo-metallic compounds according to the invention under suitable conditions, an exchange reaction between the alcohols and the groups X takes place, and the ketones can be isolated from the reaction mixture in a conventional way.
