    Abstract: The invention relates to a method for producing reactive halogen-free polyisobutene containing more than 60 mole % terminal double bonds and having a mean molecular weight Mn of between 800 and 3,000 dalton, by cationic polymerization of isobutene in the liquid phase on an acid, substantially halogen-free heterogeneous catalyst. According to said method a) an isobutene-containing hydrocarbon mixture which consists essentially of C4 hydrocarbons and contains between 10 and 80 % by weight isobutene is used as educt; and b) continuous polymerization is carried out at between -30 and 0 DEG C and mean dwell times of the educt of no more than one hour, the temperature and dwell time being chosen such that isobutene conversion is less than 60 %. After separation of the resulting polyisobutene present in the fully reacted hydrocarbon mixture the isobutene is either enriched and returned to the polymerization stage or fed to another isobutene conversion stage which is coupled to the polymerization stage.

    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).
