Abstract
A method can be used for producing alkali metal alcoholates in counter flow by reactive rectification. The alkali metal is selected from sodium and potassium. In a first part of the method, the alcohol is converted in counter flow with the respective alkali metal hydroxide. In a second part of the method, the mixture of alcohol and water obtained is separated in a rectification column, and the alcoholic vapour arising is condensed, as a result of which the temperature thereof increases. The energy dissipated during cooling of the condensed vapour is then used in the first part of the method. This permits an energy-efficient production of the alkali metal alcoholates concerned.
