    • A hydroformylation process for unsaturated compounds such as monoolefins and diolefins is carried out in an ionic medium in which the catalytic species is dissolved, but in which the reaction products (aldehydes) formed are only slightly soluble or are insoluble. The ionic medium is liquid at a temperature below 90.degree. C. and comprises at least one quaternary ammonium and/or phosphonium cation and at least one anion which is preferably selected from the group formed by tetrafluoroborate when the cation is ammonium, hexafluorophosphate, hexafluoroantimonate, hexafluoroarsenate, perfluoroalkylsulphonates, fluorosulphonate, bis-perfluoroalkylsulphonyl amides or dichlorocuprate, tetrachlorocuprate, tetrachloroaluminate, or trichlorozincate. At the end of the reaction, the organic phase is separated out and the polar phase containing the catalyst is used again.
    • 用于不饱和化合物如单烯烃和二烯烃的加氢甲酰化方法在其中溶解催化物质的离子介质中进行,但其中形成的反应产物(醛)仅仅是微溶或不溶解的。 离子介质在低于90℃的温度下是液体,并且包含至少一种季铵和/或鏻阳离子和至少一种阴离子,当阳离子是铵,六氟磷酸盐,六氟锑酸盐时,优选选自四氟硼酸盐形成的基团, 六氟砷酸盐,全氟烷基磺酸盐,氟磺酸盐,双全氟烷基磺酰胺或二氯磷酸盐,四氯磷酸盐,四氯铝酸盐或三氯酸锌。 在反应结束时,分离有机相,再次使用含有催化剂的极性相。
