The preparation of alkylaryl compounds takes place by
1) preparation of a mixture of, on statistical average, predominantly monobranched C
10-14
-olefins by
a) reaction of a C
4
-olefin mixture over a metathesis catalyst for the preparation of an olefin mixture comprising 2-pentene and/or 3-hexene, and optional removal of 2-pentene and/or 3-hexene, followed by dimerization of the resulting 2-pentene and/or 3-hexene over a dimerization catalyst to give a mixture comprising C
10-12
-olefins, and optionally removal of the C
10-12
-olefins, or
b) extraction of predominantly monobranched paraffins from kerosene cuts and subsequent dehydrogenation, or
c) Fischer-Tropsch synthesis of olefins or paraffins, where the paraffins are dehydrogenated, or
d) dimerization of shorter-chain internal olefins, or
e) isomerization of linear olefins or paraffins, where the isomerized paraffins are dehydrogenated,
2) reaction of the olefin mixture obtained in stage 1) with an aromatic hydrocarbon in the presence of an alkylation catalyst which contains zeolites of the faujasite type.
