    • 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.
    • 本发明涉及通过加氢甲酰化从含有C4的烃混合物中分离出1-丁烯的方法,其中包括异丁烯和1-丁烯,其中使用的催化体系由8-10族的过渡金属之一制成,优选为铑 和式(I)的双亚磷酸酯配体,其中X是具有一个或多个杂原子的二价取代或未取代的双亚烷基或双亚芳基,Y是具有一个或多个杂原子的二价取代或未取代的双亚芳基或双亚烷基 s),Z是氧或NR 9,R 1,R 2,R 3,R 4是相同或不同的取代或未取代的连接,未连接或稠合的芳基或杂芳基,并且R 9是氢或被取代或未取代的烷基或芳基, 一个或多个杂原子,其中式(I)的二亚磷酸酯配体以过渡金属的过量摩尔比为100:1至1:1使用,而1-丁烯转化率更高 比不到95% %的本异丁烯是通过加氢甲酰化从含C4的烃流中分离1-丁烯的反应方法。
