Abstract
The invention relates to a process for the preparation of saturated C -C -alcohols in which a liquid hydrogenation feed comprising at least one C -C -aldehyde is passed over a bed of a hydrogenation catalyst in the presence of a hydrogen-containing gas, which comprises adding to the hydrogenation feed an amount, homogeneously soluble therein, of a salt-like base. The addition of base suppresses side reactions, such as acetalization, aldolization, Tischtschenko reaction or ether formation.
