Abstract
The acid-catalyzed intermolecular etherification of mono- or polyhydric alcohols and acid-catalyzed ether cleavage in the presence of water may be improved if etherification or ether cleavage is carried out in the presence of an acid catalyst and, additionally, a hydrogenation catalyst under a hydrogen atmosphere. The process relates in particular to the etherification of diols, triols and tetrols with the formation of hydroxyethers.
