    Abstract: Selective synthesis of new linear alpha -olefins comprises: (1) reaction of a linear, internal olefin with a trialkyl Al compound; (2) reaction of the linear alkyl Al compound formed with an olefin; (3) introduction of the linear alpha -olefin into a self-metathesis reaction; (4) reaction of the formed olefin with a trialkyl Al compound; (5) reaction of the linear alkyl Al compound formed with an olefin and formation of a trialkyl Al compound; and (6) isolation of the desired linear alpha-olefin. New linear alpha -olefins of 6-20 carbons are synthesized selectively in the following steps: (1) reaction of a linear, internal olefin or a mixture of these and having a carbon number of (n/2)+1, where n = the number of C atoms of the desired linear alpha -olefin in a transalkylation reaction with a trialkyl Al compound in isomerization conditions, where an olefin corresponding to the alkyl radical is released and the linear olefin thus added becomes attached to the Al during isomerization with formation of a corresponding linear alkyl Al compound; (2) reaction of the linear alkyl Al compound formed with an olefin, on release of the corresponding linear alpha -olefin having a carbon number of (n/2)+1, and formation of a trialkyl Al compound; (3) introduction of the linear alpha -olefin formed into a self-metathesis reaction, in which a linear internal olefin with the desired carbon number n is formed; (4) reaction of the formed olefin of carbon number n with a trialkyl Al compound under isomerizing conditions, in which an olefin corresponding to the alkyl radical is released, and the linear internal olefin becomes attached to the Al on isomerization and formation of a corresponding linear alkyl Al compound; (5) reaction of the linear alkyl Al compound formed with an olefin on release of the linear alpha-olefin having the desired carbon number n and formation of a trialkyl Al compound; and (6) isolation of the desired linear alpha -olefin having a carbon number n. Independent claims are also included for the following: (1) preparation of hexene from butene-containing streams, preferably raffinate (II), comprises: (a) metathesis of the insertion product with optional addition of ethene; (b) removal, by distillation, of the stream obtained in a 2-3C olefin containing light boiling fraction and in a 4-6C olefin and butane containing high boiling fraction; (c) separation, by distillation, of the low boiling fraction obtained in an ethene containing fraction and a propene containing fraction, where the ethene containing fraction is returned to step a' and the propene containing fraction is removed; (d) separation, by distillation, of the high boiling fraction in a butene and butane containing low boiling fraction, a pentene containing medium boiling fraction, and in a hexene containing high boiling fraction; and (e) removal of the hexene containing high boiling fraction and optional returning of the remaining fraction to step a; (2) a process in which 2-pentene from butene containing streams, preferably raffinate II, where in the educt stream the ratio of 2-butene to 1-butene is preferably at least 1, is prepared preferably using the steps: a' to e' as above; and (3) a process in which the catalyst used in metathesis can have an inorganic support and contains a compound of a group VI, VII, or VIII metal, preferably an oxide of a group VIb or VIIb metal, especially a metathesis catalyst selected from: Re2O7, WO3, and MoO3, most preferred catalyst Re2O7, on psi -Al2O3, or Al2O3/B2O3/SiO2 mixed supports.

    Abstract: The invention relates to a method for the production of propene by multiple execution of the following sequence of steps, whereby in step 1 a mixture M1, essentially comprising unbranched C4- to C9 monoolefins (Components 04-9), 0 to 15 mol. % ethylene (component E), based on the components 04-9, 0 to 100 mol. % saturated hydrocarbons (components KG), based on the components 04-9, 0 to 30 mol. % olefins with more than 9 hydrocarbon atoms (components 0>9), based on components 04-9, 0 to 1 mol. %, based on the components 04-9, propene (component 03), 0 to 10 mol. %, based on the components 04-9, of other hydrocarbons (components KS), is brought into contact with a metathesis catalyst at a temperature of 20 to 350° C., with the proviso that the molar proportion of the sum of the 1-olefins and the sum of the 2-olefins to the sum of the components 04-9 and 0>9 is at least 0.5%, so long as the mixture M1 is not simultaneously or previously subjected to an isomerisation, correspondingly changing the proportion of 1- and 2-olefins, thus producing a mixture M2. In step II a mixture M1 is produced from a mixture M2 whereby a) propene and optionally components 0>9 and components KS are completely or partially removed and b) amounts of components 04-09 are added, a maximum of 1 mol. % of component E, based on the added amounts of components 04-09 and optionally other saturated or olefinically-unsaturated hydrocarbons, based on the added amounts of components 04-09, are added.
