    • An improved hydroformylation catalyst cycle is disclosed wherein the cobalt catalyst is recycled to the hydroformylation reaction mainly as a water soluble carbonyl salt, obtained from extraction of the acidic form of the homogeneous cobalt carbonyl catalyst from the hydroformylation product with an aqueous solution of a salt of a weaker acid. The organic product after extraction is submitted to a further demetalling step in the presence of a dilute acid and an oxidant. The water from this further demetalling step is suitable for use in the upstream extraction step. A free water phase present in the hydroformylation reaction product may be separated upstream from the extraction step and is suitable for use in the further demetalling step, such that the catalyst cycle has no waste water stream.
    • 公开了一种改进的加氢甲酰化催化剂循环,其中主要以水溶性羰基盐将钴催化剂再循环至加氢甲酰化反应,该水溶性羰基盐是从加氢甲酰化产物中提取酸性形式的均匀钴羰基催化剂得到的, 酸弱。 提取后的有机产物在稀酸和氧化剂存在下进一步脱金属步骤。 来自该进一步脱金属步骤的水适用于上游萃取步骤。 存在于加氢甲酰化反应产物中的游离水相可以从萃取步骤的上游分离,并且适合用于进一步脱金属步骤,使得催化剂循环不含废水流。

    • A compound comprising a sulfonated triorganophosphine of formula R1R2PR3[SO3M)]n, wherein R1 and R2 are selected individually from alkyl, aralkyl, and alicyclic groups; wherein R3 represents a branched divalent or polyvalent, alkylene or alicyclic radical that is bonded to the phosphorus atom and to one or more sulfonate substituents, and further wherein R3 does not contain any aryl moieties; M represents a monovalent cation; and n is an integer representing a total number of sulfonated substituents. The compound is useful as a ligand in transition metal-ligand complex catalysts that are capable of catalyzing the hydroformylation of an olefinically-unsaturated compound with carbon monoxide and hydrogen to form one or more corresponding aldehyde products. The ligand is incapable of alkyl-aryl exchange, thereby leading to reduced ligand usage and improving ligand and transition metal, e.g., rhodium, recovery and recycling, as compared with prior art ligands.
    • 包含式R 1 R 2 PR 3 [SO 3 M]] n的磺化三有机膦的化合物,其中R 1和R 2分别选自烷基,芳烷基和脂环基; 其中R3表示与磷原子和一个或多个磺酸酯取代基结合的支链二价或多价亚烷基或脂环族基团,其中R3不含任何芳基部分; M表示一价阳离子; n为代表磺化取代基总数的整数。 该化合物可用作过渡金属 - 配体配合物催化剂中的配体,其能够催化烯属不饱和化合物与一氧化碳和氢气的羰基化形成一种或多种相应的醛产物。 与现有技术的配体相比,配体不能进行烷基 - 芳基交换,从而导致配体使用减少并改善配体和过渡金属,例如铑,回收和再循环。
