    Abstract: Production of alkylaromatic compounds (I), by reacting 3-30C olefins (II) (or alcohols forming (II) under the reaction conditions) with aromatic hydrocarbons (III) in presence of an alkylation catalyst (IV), is carried out in a cascade of at least two reactors each containing (IV), where at least 80 % of (III) is supplied to the first reactor of the cascade and at least 40 % of (II) is supplied after the first reactor. An independent claim is included for the preparation of alkylarylsulfonates (A), by: (1) converting a 4C olefin mixture over a metathesis catalyst to give an olefin mixture containing 2-pentene and/or 2-hexene; (2) catalytically dimerizing the 2-pentene and/or 2-hexene (optionally after isolation) to give a mixture containing 10-12C olefins, optionally separating the 10-12C olefins and separating 5-30 wt. % (based on the 10-12C olefins) of low-boiling components of the 10-12C olefins; (3) reacting the obtained 10-12C olefin mixture with (III) in presence of (IV) to give alkylaromatic compounds (I'), optionally with addition of 0-60 wt. % (based on the 10-12C olefin mixture) of linear olefins before the reaction; (4) sulfonating (I') and neutralizing to give (A), optionally with addition of 0-60 wt. % (based on (I')) of linear alkylbenzenes (provided that no mixing has been carried out in the previous step); and (5) optionally mixing the obtained (A) with optionally with addition of 0-60 wt. % (based on (A)) of linear aralkylsulfonates (provided that no mixing has been carried out either of the previous two steps); The novel feature being that the reaction in the alkylation stage (3) is carried out as for the present procedure for preparing (I).

    Abstract: The invention relates to a process for the preparation of alkylarylsulfonates by a) reaction of a C 4 -olefin mixture over a metathesis catalyst for the preparation of an olefin mixture comprising 2-pentene and/or 3-hexene, and optional removal of 2-pentene and/or 3-hexene, b) dimerization of the 2-pentene and/or 3-hexene obtained in stage a) over a dimerization catalyst to give a mixture containing C 10-12 -olefins, and optional removal of the C 10-12 -olefins, c) reaction of the C 10-12 -olefin mixtures obtained in stage b) with an aromatic hydrocarbon in the presence of an alkylating catalyst to form alkylaromatic compounds, where, prior to the reaction, additional linear olefins may be added, d) sulfonation of the alkylaromatic compounds obtained in stage c), and neutralization to give alkylarylsulfonates, where, prior to the sulfonation, linear alkylbenzenes may additionally be added, e) optional mixing of the alkylarylsulfonates obtained in stage d) with linear alkylarylsulfonates.

    Abstract: The production of alkyl aryl compounds can be achieved by the following step s: 1) production of an olefin mixture, comprising, as a statistical mean, predominantly single-branched C10-14 olefins, by means of a) reaction of a C 4 olefin mixture on a metathesis catalyst to give an olefin mixture containing 2- pentene and/or 3-hexene and optional separation of 2-pentene and/or 3-hexene , followed by dimerisation of the obtained 2-pentene and/or 3-hexene on a dimerisation catalyst to give a mixture containing C10-12 olefins and option al separation of the C10-12 olefins, or b) extraction of predominantly single- branched paraffins from kerosene fractions and subsequent dehydrogenation, o r c) Fischer-Tropsch synthesis of olefins or paraffins, whereby the paraffins are dehydrogenated, or d) dimerisation of short-chain internal olefins, or e ) isomerisation of linear olefins or paraffins, whereby the isomerised paraffi ns are dehydrogenated, 2) reaction of the olefin mixture obtained in step 1) wi th an aromatic hydrocarbon in the presence of an alkylation catalyst containing zeolites of the faujasite type.
