Abstract: The invention relates to a method of preparing surface-active alcohols and surface-active alcoholic ethers which are well suited for use as surface-active agents or for the preparation of surface-active agents. To this end, olefin mixtures containing a predominant share of branched dodecenes are prepared from olefin mixtures containing less than 30 % by weight linear hexene isomers, using a catalyst containing nickel, and derivatized to form surface-active alcohols which are then possibly alkoxylated. The invention also relates to the use of said surface-active alcohols and surface-active alcoholic ethers for the preparation of surface-active agents by glycosidation or polyglycosidation, sulfation or phosphation.

Abstract: The invention relates to a supported catalyst containing at least one water-soluble transition metal complex. The supported catalyst is characterized in that polymeric particles having a hydrophobic core and hydrophilic side-chains are utilized as a support. In the examples, tentagel, polymeric particles comprised of a cross-linked polystyrene core with polyethylene glycol side-chains grafted thereon are utilized as supports. The transition metal is selected from metals of groups VIIB, VII, IB or IIB of the periodic table and from mixtures thereof.
