A process for the preparation of alkylarylsulfonates by a modified, dimerized olefins

The invention relates to processes for the preparation of alkylarylsulfonates by a) reaction of a C b) dimerization of the obtained in step a) 2-pentene and / or 3-hexene in the presence of a dimerization catalyst to give a C c) reacting the C obtained in step b) d) sulfonation in stage c) alkyl aromatic compounds obtained and neutralization to give alkylarylsulfonates, where, in addition linear alkylbenzenes can be added prior to the sulfonation, e) optionally mixing the mixture obtained in stage d) with linear alkylarylsulfonates alkylarylsulfonates.
