The invention relates to a method for producing novel surfactant alcohols and surfactant alcohol ethers by derivatising olefins with approximately 10 to 20 C-atoms or mixtures of such olefins to produce alkanols and optionally, subsequently alkoxylating them. The method is characterised in that a C4- olefin-mixture is subjected to metathesis, the resulting olefins are dimerised and then derivatised to produce surfactant alcohols, and these are optionally alkoxylated. The olefin mixture obtained from dimerisation contains a large proportion of branched components and less than 10 wt. % of compounds containing a vinylidene group. The invention also relates to the use of surfactant alcohols and surfactant alcohol ethers for producing surfactants by glycosylation or polyglycosylation, sulphation or phosphation.

L'invention concerne un procédé de production de nouveaux alcools tensioactifs et éthers d'alcools tensioactifs, par dérivatisation d'oléfines comportant environ 10 à 20 atomes de carbone ou de mélanges de telles oléfines pour former des alcanols, la dérivatisation étant suivie éventuellement par une alcoxylation. L'invention est caractérisée en ce que l'on soumet un mélange d'oléfines C¿4? à une métathèse, on effectue une dimérisation des oléfines obtenues, puis une dérivatisation pour former des alcools tensioactifs, ces derniers étant ensuite éventuellement alcoxylés. Le mélange d'oléfine obtenue lors de la dimérisation présente une teneur élevée en composants ramifiés, et contient moins de 10 % en poids de composés renfermant un groupe vinylidène. L'invention concerne en outre l'utilisation d'alcools tensioactifs et d'éthers d'alcools tensioactifs pour la production de tensioactifs par glycosidation ou polyglycosidation, sulfatation ou phosphatation.
