    摘要： The invention relates to a method for separating 1-butene from C4-containing hydrocarbon mixtures, comprising isobutene and 1-butene, by hydroformylation, wherein the catalytic system used is made of one of the transition metals of the group 8 to 10, preferably rhodium, and a bisphosphite ligand of the formula (I), where X is a divalent substituted or unsubstituted bisalkylene or bisarylene group having one or more heteroatom(s), Y is a divalent substituted or unsubstituted bisarylene or bisalkylene group having one or more heteroatom(s), Z is oxygen or NR9, and R1, R2, R3, R4 are identical or different, substituted or unsubstituted, linked, unlinked or condensed aryl or heteroaryl groups, and R9 is hydrogen or a substituted or unsubstituted alkyl or aryl group having one or more heteroatom(s), wherein the bisphosphite ligand of the formula (I) is used in an excess of a molar ratio of 100:1 to 1:1 to the transition metal, and that with a 1-butene conversion of more than 95% less than 5% of the present isobutene is reacted method for separating 1-butene from c4-containing hydrocarbon streams by hydroformylation.
