    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: Producing slightly branched alkylaromatics by alkylating aromatics with olefins in the presence of an acid catalyst comprises reducing the hydroperoxide content of the olefin feed to less than 1 g per kg of catalyst per hour by treatment with an inorganic hydride. An independent claim is also included for producing alkylaryl sulfonates by contacting a C4 olefin mixture with a metathesis catalyst to produce an olefin mixture containing 2-pentene and/or 3-hexene; optionally separating the 2-pentene and/or 3-hexene; dimerizing the 2-pentene and/or 3-hexene, optionally together with C4 and/or C7 olefins, in the presence of a dimerization catalyst, to give a C8-C14 olefin mixture; optionally separating the C8-C14 olefins and separating 5-30 wt.% of low boilers; reducing the hydroperoxide content of the C8-C14 olefin mixture as above; optionally adding linear olefins in an amount of 0-60 wt.%; reacting the C8-C14 olefin mixture with aromatics in the presence of an acid catalyst to produce alkylaromatics; optionally adding linear alkylbenzenes in an amount of 0-60 wt.%; sulfonating the alkylaromatics and neutralizing the products to give alkylaryl sulfonates; and optionally mixing the alkylaryl sulfonates with 0-60 wt.% (words missing).

    Abstract: In a process for preparing alkylaryl compounds by reacting a C10-14-monoolefin mixture with an aromatic hydrocarbon in the presence of an alkylation catalyst to form alkyl aromatic compounds and if appropriate subsequently sulfonating and neutralizing the resulting alkylaryl compounds, in the C10-14-monoolefins, on average, more than 0% and up to 100% of methyl branches are present in the longest carbon chain and fewer than 50% of the methyl branches are in the 2-, 3- and 4-position, calculated starting from the chain ends of the longest carbon chain.

    Abstract: The invention relates to methods for producing alkyl aryl sulphonates by a) reaction of a C4 olefin mixture on a methathetical catalyst to produce an olefin mixture containing 2 pentene and/or 3 hexene and optionally the separation of 2 pentene and/or 3 hexene, b) dimerisation of the 2 pentene and/or 3 hexene obtained in stage a) on a dimerisation catalyst to obtain a mixture containing C10-12 olefins and the optional separation of said C10-12 olefins, c) reaction of the C10-12 olefin mixtures obtained in stage b) with an aromatic hydrocarbon in the presence of an alkylation catalyst for formin g alkyl aromatic compounds, whereby linear olefins can also be added prior to the reaction, d) sulphonation of the alkyl aromatic compound obtained in sta ge c) and neutralisation of the same to form alkyl aryl sulphonates, whereby linear alkyl benzoles can also be added prior to sulphonation, e) optional mixing of the alkyl aryl sulphonates obtained in stage d) with linear alkyl aryl sulphonates.
