    Abstract: Production of propene (Pr) from a mixture (M1) that comprises: (1) ethylene (E); (2) hexenes (H); (3) other olefins (K1a); and (4) optionally other inert hydrocarbons (K1b). The mixture is contacted with a metathesis catalyst (MC) at 20-350 deg C. Production of propene from a mixture (M1) that comprises: (1) ethylene (E); (2) hexenes (H); (3) other olefins (K1a); and (4) optionally other inert hydrocarbons (K1b). The mixture is contacted with a metathesis catalyst (MC) at 20-350 deg C. The mixture (M1) has: (i) a molar proportion of the sum of 2-hexene (H2) and 3-hexene (H3) in (H) of 4-99:1; (ii) a molar ratio of (E) to the sum of (H) and (K1a) of 1-100:1; and (iii) a ratio of (H2) to (H3) of at least 2:1, as long as (H3) is not simultaneously isomerized to increase the (H2) proportion correspondingly.

    Abstract: The invention relates to a method for selective production of linear .alpha. - olefins having a carbon number ranging from 6 20, comprising the following steps: a) reaction of a linear, internal olefin or a mixture of linear, internal olefins having a carbon number of (n/2) + 1, wherein n is the carbo n number of the desired linear .alpha.-olefin, in a transalkylation with a trialkyl aluminium compound in isomerizing conditions, wherein an olefin corresponding to the alkyl radical is released and the linear olefin thus added becomes attached to the aluminium during isomerization and the formati on of a corresponding linear alkyl aluminium compound; b) reaction of the forme d linear alkyl aluminium compound with an olefin upon release of the corresponding linear .alpha. olefin having a carbon number of (n/2) + 1 and formation of a trialkyl aluminium compound, c) introduction of the formed linear .alpha.-olefin into a self methathesis reaction, wherein a linear internal olefin having the desired carbon number n is formed, d) reaction of the formed olefin having a carbon number n with a trialkyl aluminium compoun d in isomerizing conditions, wherein an olefin corresponding to the alkyl radical is released and the linear, internal olefin becomes attached to the aluminium upon isomerization and formation of a corresponding linear alkyl aluminium compound e) reaction of the formed linear alkyl aluminium compound with an olefin upon release of the linear .alpha.-olefin having the desired carbon number n and formation of a triialkylaluminium compound; f) isolation of the desired linear .alpha.-olefin having a carbon number n.

    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.
