    • The preparation of alkylaryl compounds takes place by a) reaction of a C4/C5-olefin mixture over a metathesis catalyst to prepare a C4-8-olefin mixture comprising 2-pentene, and optional removal of the C4-8-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 C4-8-olefin mixture obtained in stage b) following removal in the presence of a dimerization catalyst to give a mixture containing C8-16-olefins, removal of these C8-16-olefins and optional removal of a partial stream thereof, d) reaction of the c8-16-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 c8-16-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).
    • 烷基芳基化合物的制备通过以下步骤进行:a)在复分解催化剂上使C 4-14 C 5 -C 5 - 烯烃混合物反应以制备C 4-8 - 其包含2-戊烯,任选地除去C 4-18α-烯烃混合物,b)除去在步骤a)中存在的5-100%的2-戊烯, 并随后在异构化催化剂上反应,得到2-戊烯和1-戊烯的混合物,将其返回到a)步骤,c)在步骤b中获得的C 4-18α-烯烃混合物的二聚反应 ),在二聚催化剂存在下除去,得到含有C 8-16 - 烯烃的混合物,除去这些C 8-16 - 烯烃并任选地除去 其部分流,d)在烷基化催化剂存在下,将阶段c)或部分流中获得的C 8-16 - α-烯烃混合物与芳族烃反应,形成烷基芳族化合物,其中 在反应之前,0至60重量%,b 在阶段c)中得到的C 8-16α-烯烃混合物中,可以另外加入线性烯烃,e)任选的在步骤d)中获得的烷基芳族化合物磺化,中和得到烷基芳基磺酸盐 ,其中在磺化之前,如果在步骤d)中没有混合,则可以另外加入基于直链烷基苯中得到的直链烷基苯0至60重量%,f)任选混合 如果在阶段d)和e)中没有混合,则在阶段e)中获得的烷基芳基磺酸盐以0至60重量%的量计,基于阶段e)中得到的烷基芳基磺酸盐,为直链烷基芳基磺酸盐。
