Abstract: The invention relates to a process for the preparation of saturated C3-C20-alcohols in which a liquid hydrogenation feed comprising at least one C3-C20-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.

Abstract: The invention describes a process for the preparation of surfactant alcohols and surfactant alcohol ethers which are, inter alia, highly suitable as surfactants or for the preparation of surfactants. The process, starting from olefin mixtures having a defined minimum content of linear hexenes, gives mixtures having a predominant fraction of branched dodecenes, which are subsequently derivatized to give surfactant alcohols and then optionally alkoxylated. The surfactant alcohol mixture obtained in the process has a degree of branching of from 2.0 to 3.0 and in particular exhibits advantageous properties as regards ecotoxicity and biodegradability. A description is also given of the use of the surfactant alcohols and surfactant alcohol ethers as surfactants by glycosidation or polyglycosidation, sulfation or phosphation.
