    • The production of alkylaryl compounds comprises the following stages: a) reaction of a C4/C5 olefin mixture on a metathesis catalyst to produce a C 4-8 olefin mixture containing 2-pentene and the optional isolation of the C 4-8 olefin mixture; b) isolation of between 5 and 100 % of the 2-pentene obtained in step a) and subsequent reaction on an isomerisation catalyst to form a mixture of 2-pentene and 1-pentene, which is returned to stage a); c) dimerisation of the C 4-8 olefin mixture obtained in stage b) after the isolation process, to form a mixture containing C 8-16 olefins, isolation of the C 8-16 olefins and optional isolation of a partial stream of the latter; d) reaction of the C 8-16 olefin mixtures obtained in stage c) or the partial stream with an aromatic hydrocarbon in the presence of an alkylation catalyst, to form alkyl aromatic compounds, whereby prior to the reaction an additional 0 to 60 wt. % linear olefins, in relation to the C 8-16 olefin mixtures obtained in stage c), can be added; e) optional sulphonation of the alkyl aromatic compounds obtained in stage d) and neutralisation to form alkylaryl sulphonates, whereby prior to the sulphonation an additional 0 to 60 wt. % linear alkyl benzols, in relation to the alkyl aromatic compounds obtained in stage d), can be added, provided that there were no admixtures in stage d); f) optional mixing of the alkylaryl sulphonates obtained in stage e) with between 0 and 60 wt. %, linear alkylaryl sulphonates, in relation to the alkylaryl sulphonates obtained in stage e), provided that there were no admixtures in stages d) and e).

    • The invention relates to a method for producing optionally akyl-substituted 1,4-butandiol by two-stage catalytic hydration in the gaseous phase of C4 dicarboxylic acids and/or the derivatives thereof with the steps of: a) introducing a gaseous flow of a C4 dicarboxylic acid or a derivative thereof at 200 to 300 °C and 2 to 60 bar in a first reactor and catalytic gas phase hydration to a mainly optionally alkyl-substituted gamma-butyrolactone containing product; b) introducing the product flow so obtained into a second reactor at a temperature of from 150 °C to 240 °C and a pressure of from 15 to 100 bar and catalytic gas phase hydration to optionally alkyl-substituted 1,4-butandiol; c) removing the desired product from the intermediates, byproducts and possibly not reacted educt; d) optionally returning non-reacted intermediates to one or both hydration stages, whereby in both hydration stages one catalyst each is used which comprises = 5 % by weight, preferably 5 to 95 % by weight, especially 20 to 90 % by weight of an oxidic carrier, the pressure prevailing in the second reactor is higher than in the first reactor, and the product mixture removed from the first reactor is introduced into the second reactor without further purifying it.
