    Abstract: The preparation of alkylaryl compounds takes place by a) reaction of a C 4 /C 5 -olefin mixture over a metathesis catalyst to prepare a C 4-8 -olefin mixture comprising 2-pentene, and optional removal of the C 4-8 -olefin mixture, b) removal of from 5 to 100% of the 2-pentene present in stage a) and subsequent reaction over an isomerization catalyst to give a mixture of 2-pentene and 1-pentene which is returned to stage a), c) dimerization of the C 4-8 -olefin mixture obtained in stage b) following removal in the presence of a dimerization catalyst to give a mixture containing C 8-16 -olefins, removal of these C 8-16 -olefins and optional removal of a partial stream thereof, d) reaction of the c 8-16 -olefin mixtures obtained in stage c) or of the partial stream with an aromatic hydrocarbon in the presence of an alkylation catalyst to form alkyl aromatic compounds where, prior to the reaction, 0 to 60% by weight, based on the c 8-16 -olefin mixtures obtained in stage c), of linear olefins may additionally be added, e) optional sulfonation of the alkyl aromatic compounds obtained in stage d) and neutralization to give alkylarylsulfonates, where, prior to the sulfonation, 0 to 60% by weight, based on the alkyl aromatic compounds obtained in stage d), of linear alkylbenzenes may additionally be added if no admixing has taken place in stage d), f) optional mixing of the alkylarylsulfonates obtained in stage e) with 0 to 60% by weight, based on the alkylarylsulfonates obtained in stage e), of linear alkylarylsulfonate, if no admixing has taken place in stages d) and e).

    Abstract: A process for preparing 1-butene, which includes nonoxidatively, catalytically dehydrogenating n-butane to obtain a product gas stream of n-butane, 1-butene, 2-butene, butadiene, hydrogen, and secondary constituents; removing hydrogen and the secondary constituents to obtain a C4 product gas stream; separating the C4 product stream into a recycle stream of n-butane and a stream of 1-butene, 2-butene and butadiene by extractive distillation, and recirculating the recycle stream to the dehydrogenation zone; introducing the 1 -butene, 2-butene and butadiene stream into a selective hydrogenation zone and selective hydrogenation of butadiene to 1-butene and/or 2-butene to obtain a stream of 1-butene and 2-butene; introducing the 1-butene and 2-butene stream, and a circulating stream of 1-butene and 2-butene into a distillation zone and isolation of a product stream; and introducing the 2-butene-containing stream into an isomerization zone to obtain a circulating stream of 1-butene and 2-butene, and recirculating the circulating stream to the distillation 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: A process for the continuous production of 1,3-dioxolan-2-ones such as ethylene carbonate or propylene carbonate by reacting a corresponding oxirane with carbon dioxide in the liquid phase in the presence of a catalyst comprises conducting the reaction in a two-part reactor in whose first part the reaction is taken with backmixing to a conversion of not less than 80% of the oxirane II and in whose second part the reaction is completed under nonbackmixing conditions, and passing the carbon dioxide in countercurrent to the oxirane II in the entire reactor.
