Abstract: The invention relates to a method for producing alkyl aromatic compounds by reacting C3-30 olefins or alcohols, from which C3-30 olefins are formed under the reaction conditions, with an aromatic hydrocarbon in the presence of an alkylation catalyst. The reaction is carried out in a reactor cascade consisting of at least two reactors, whereby each of the reactors contain the alkylation catalyst, at least 80 % of the aromatic hydrocarbon is fed into the first reactor of the reactor cascade, and at least 40 % of the olefins are fed in an intermediate manner after the first reactor.

Abstract: Disclosed is a method for hydrating hydrocarbon compounds selected among the group comprising alkynes, dienes, alkenynes, and polyenes (hydrocarbons I). According to the inventive method, a gas stream containing hydrogen and a hydrocarbon I is directed through a hydration zone containing a hydration catalyst. The beginning of the hydration zone is located at a point whose geodetic height is lower than that of the end of the hydration zone.

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: Process for the production of at least one alkanolamine by reaction of ammonia with alkylene oxide. The process is carried out in a reactor in the presence of a catalyst and yields mono-, di and/or trialkanolamines. The distribution of the different alkanolamines is regulated by the temperature in the reactor, which is characterized by adjustment of the temperature by regulation of the temperature profile in the reactor.
