    摘要： A process for the combined preparation of a butene and an octene from ethene, proceeds by: a) providing a solvent having a boiling point or boiling range above the boiling points of the butenes and below the boiling points of the octenes and wherein the solvent is an inert solvent or is hexene alone or is hexene admixed with pentane or hexane or heptane or is a mixture of pentane, hexane, and heptane; b) providing a first feed mixture containing at least the solvent and ethene dissolved therein; c) providing a second feed mixture containing at least hexene, the solvent and also ethene dissolved in the solvent and/or in the hexene; d) transferring the first feed mixture into a first synthesis and the second feed mixture into a second synthesis, wherein the first and second syntheses are physically separated from one another; e) oligomerising of at least part of the ethene present in the first feed mixture in the presence of a first heterogeneous catalyst and in the presence of the solvent in the first synthesis to give a first reaction mixture comprising at least the solvent, butene and hexene; f) separating a butene-containing low boiler fraction from the first reaction mixture or from a stream based on the first reaction mixture; g) separating an intermediate boiler fraction containing hexene and the solvent from the first reaction mixture or from a stream based on the first reaction mixture; h) using at least part of the intermediate boiler fraction in the course of providing the second feed mixture; and i) reacting at least part of the ethene present in the second feed mixture with at least part of the hexene present in the second feed mixture in the presence of a second heterogeneous catalyst and in the presence of the solvent in the second synthesis to give a second reaction mixture comprising at least octene and the solvent.
