METHOD FOR SEPARATING 1-BUTENE FROM C4-CONTAINING HYDROCARBON STREAMS BY HYDROFORMYLATION

METHOD FOR SEPARATING 1-BUTENE FROM C4-CONTAINING HYDROCARBON STREAMS BY HYDROFORMYLATION

Separation of 1-butene from 4C hydrocarbon mixture containing isobutene and 1-butene by hydroformylation, is claimed, where: a catalyst system used in the process is a transition metal of the groups 8-10, preferably rhodium, and a bisphosphite ligand (I), which is used in an excess molar ratio of 10...

Zusammenfassung:Separation of 1-butene from 4C hydrocarbon mixture containing isobutene and 1-butene by hydroformylation, is claimed, where: a catalyst system used in the process is a transition metal of the groups 8-10, preferably rhodium, and a bisphosphite ligand (I), which is used in an excess molar ratio of 100:1-1:1 to the transition metal; and 5-95% of 1-butene is converted to isobutene. Separation of 1-butene from 4C hydrocarbon mixture containing isobutene and 1-butene by hydroformylation, is claimed, where: a catalyst system used in the process is a transition metal of the groups 8-10, preferably rhodium, and a bisphosphite ligand of formula (I), which is used in an excess molar ratio of 100:1-1:1 to the transition metal; and 5-95% of 1-butene is converted to isobutene. X, Y 1> : bivalent optionally substituted bisalkylene- or bisarylene residue containing one or more heteroatom; Z : O or NR 9>; R 1>-R 4> : optionally substituted, optionally linked or condensed (hetero)aryl; and R 9> : alkyl or aryl (both optionally substituted and containing one or more heteroatom) or H.
