Abstract: The invention relates to a method for oligomerizing olefins according to which an olefin is brought into contact with a catalyst system comprising: a) at least one transition metal complex having a multidentate complex ligand, and; b) an alkylalumoxane in quantities in which the molar ratio of aluminum to transition metal is greater than 10, whereby at least one portion of the quantity of the transition complex is added continuously or in portions over the course of oligomerization. The method enables the production of greater quantities of olefin oligomers with a given quantity of alkylalumoxane.

Abstract: A process for preparing surfactant alcohols and surfactant alcohol ethers by derivatization of olefins having about 10 to 20 carbon atoms or of mixtures of such olefins and optional subsequent alkoxylation is described. As features, the process involves (a) subjecting a C4-olefin mixture with a 1-butene/2-butene ratio of ?1.2 to a metathesis, (b) separating off olefins having 5 to 8 carbon atoms from the metathesis mixture, (c) subjecting the separated-off olefins individually or in a mixture to a dimerization to give olefin mixtures having 10 to 16 carbon atoms, (d) subjecting the resulting olefin mixture, optionally after a fractionation, to derivatization to give a mixture of surfactant alcohols and (e) optionally alkoxylating the surfactant alcohols. The olefin mixture obtained in the dimerization comprises a high content of branched components and less than 10% by weight of compounds which contain a vinylidene group.
