    Abstract: A process for coproducing alkyl-substituted or unsubstituted THF and pyrrolidones by catalytically hydrogenating C 4 -dicarboxylic acids and/or derivatives thereof in the gas phase in the presence of copper catalysts and reacting GBL with ammonia or primary amines to give pyrrolidones comprises a) hydrogenating C 4 -dicarboxylic acids and/or derivatives thereof in the gas phase at from 200 to 300° C., from 0.1 to 100 bar, catalyst hourly space velocities of from 0.01 to 1 kg of reactant/l of catalyst*hour and reactant/hydrogen molar ratios of from 20 to 800 in the presence of catalysts comprising copper, aluminum and/or zinc to give mixtures of THF and GBL, b) separating the hydrogenation effluent obtained by distillation into a THF/water mixture as the top product and a GBL-containing bottom product, c) separating the THF/water mixture from step b) in a distillation facility consisting of three columns by withdrawing water from the bottom of the first column, recycling water-containing THF from the second into the first column, passing a side stream of the first into the second column, recycling the bottom product of the third column into the first column and withdrawing a distillate at the top of the first column, wherein a side stream of the second column is passed into the third column and the pure THF is obtained as the top product of the third column, d) recovering GBL from the GBL-containing bottom product from step b) by distillation and e) reacting the GBL obtained with ammonia or amines to give corresponding pyrrolidones.

    Abstract: The present invention relates to a process for preparing alkylaromatics by reacting aromatic compounds with C1-C14-alkanes in the presence of a heterogeneous catalyst, which comprises using as the catalyst a crystalline, micro- and/or mesoporous solid comprising silicon and at least one father element selected from the group consisting of the transition metals and the main group elements gallium and tin, and activating said catalysts by a reducing pretreatment. Furthermore, the present invention relates to a process for preparing alkylarylsulfonates by sulfonating and neutralizing the alkyl aromatic compounds.

    Abstract: Crude water-containing tetrahydrofuran is purified by passing the crude tetrahydrofuran through three distillation columns, withdrawing water from the bottom of the first column, recycling water-containing tetrahydrofuran from the top of the second column into the first column, passing a sidestream of the first column into the second column, recycling the bottom product of the third column into the first column, and withdrawing a distillate at the top of the first column. Additionally, a sidestream of the second column is passed into the third column and the purified tetrahydrofuran is recovered as the top product of the third column.

    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.
