    • In general, when Brønsted acid catalysis is employed for the ether synthesis from two alcohols, water has to be removed to achieve complete conversion, because also the back reaction, that is, the conversion of an ether into two alcohols in the presence of water, is catalyzed by Brønsted acids. In the case of the solid Lewis acids, this back reaction is not facilitated by the catalyst. The ether may coordinate to the Lewis acid center, however, it will not be activated for the ether hydrolysis as the alcoholate is not converted into a better leaving group
