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. Also described is the use of surfactant alcohols and surfactant alcohol ethers to give surfactans by glycosidation or polyglycosidation, sulfation or phosphation.
