Verfahren zur intermolekularen Veretherung und zur Etherspaltung
摘要
Intermolecular etherification of mono- or multivalent alcohols is carried out in the presence of an additional acid-stable hydrogenation catalyst in a hydrogen atmosphere. Process for the intermolecular etherification of mono- or multivalent alcohols and ether splitting comprises treating the alcohol in the case of etherification or the ether in the case of ether splitting in the aqueous phase in the presence of an acid catalyst at at least 100 degrees C and then treatment is carried out using an acid-stable hydrogenation catalyst in a hydrogen atmosphere.
