    • The production of alkylaryl compounds comprises the following stages: a) reaction of a C4/C5 olefin mixture on a metathesis catalyst to produce a C4-8 olefin mixture containing 2-pentene and the optional isolation of the C4-8 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 C4-8olefin mixture obtained in stage b) after the isolation process, to form a mixture containing C8-16 olefins, isolation of the C8- 16 olefins and optional isolation of a partial stream of the latter; d) reaction of the C8-16olefin 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 C8-16 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).
    • 烷基芳基化合物的生产包括以下阶段:a)C4 / C5烯烃混合物在复分解催化剂上的反应,以产生含有2-戊烯的C 4-8烯烃混合物和任选的C4-8烯烃混合物的分离; b)分离步骤a)中获得的5-100%的2-戊烯和在异构化催化剂上的后续反应,形成2-戊烯和1-戊烯的混合物,将其返回到a)阶段; c)在分离过程之后在阶段b)中获得的C4-8烯烃混合物的二聚,形成含有C8-16烯烃的混合物,分离C8-16烯烃并任选分离后者的部分流; d)在烷基化催化剂存在下,将步骤c)中获得的C8-16烯烃混合物或部分物流与芳族烃反应,形成烷基芳族化合物,由此在反应之前,再加入0至60wt。 可以加入相对于阶段c)中得到的C8-16烯烃混合物的直链烯烃; e)在步骤d)中获得的烷基芳族化合物的任选磺化和中和以形成烷基芳基磺酸盐,由此在磺化之前,另外加入0至60wt。 可以加入相对于阶段d)中获得的烷基芳族化合物的直链烷基苯酚,条件是在d)阶段中不存在混合物; f)任选地将阶段e)中获得的烷基芳基磺酸盐与0至60wt。 %,线性烷基芳基磺酸盐,相对于阶段e)中获得的烷基芳基磺酸盐,条件是在阶段d)和e)中没有混合物。
