    • A process for the preparation of aldehydes or aldehydes and alcohols by hydroformylation of olefins containing more than 3 carbon atoms, comprising a hydroformylation stage, in which the olefin is hydroformylated under a pressure of form 50 to 1000 bar and at a temperature of from 50° to 180° C. by means of a rhodium catalyst dissolved in a homogenous reaction medium and a catalyst recovery stage comprising extraction of the rhodium catalyst with an aqueous solution of chelating agent, isolation of alcohols and/or aldehyde from the extracted hydroformylation product steam, precarbonylation of the aqueous rhodium-containing extract in the presence of carbon monoxide, synthesis gas as, or a gas mixture containing carbon monoxide under a pressure of from 50 to 1000 bar and at a temperature of from 50° to 180° C., separation of the effluent of the precarbonylation stage into an organic phase containing the major portion of the rhodium and an aqueous phase containing the chelating agent and recycling of the organic phase to the hydroformylation stage, where the rhodium catalyst is extracted from the effluent of the hydroformylation stage using an aqueous solution of a sulfonic acid group-free, water-soluble polymer capable of chelating rhodium.

    • A process for producing a rhodium complex solution, which comprises contacting an aqueous solution of a water-soluble rhodium compound and an organic solvent solution of a water-insoluble tertiary organic phosphorus compound, preferably in the presence of a C.sub.2-8 carboxylic acid, in a gas atmosphere containing carbon monoxide, followed by two phase separation, and recovering an organic solvent phase containing a rhodium-tertiary organic phosphorus compound complex. As the above aqueous solution of a rhodium compound, an aqueous solution having rhodium extracted into an aqueous phase from a waste catalyst liquid separated from a hydroformylation reaction step by oxidation treatment in the presence of a recovery accelerator such as a carboxylic acid, an amine, ammonia or an inorganic acid, is used, whereby recycling of rhodium represented by hydroformylation reaction/recovery of the catalyst/regeneration of the catalyst, is made possible, and a cumbersome step of preparing a complex catalyst from an inorganic salt or the like, or a step of preparing a soluble salt from a metal or oxide by combustion in water of the recovered catalyst, can be omitted.
    • 一种制备铑络合物溶液的方法,其包括使水溶性铑化合物的水溶液与水不溶性叔有机磷化合物的有机溶剂溶液,优选在C2-8羧酸存在下,在 含有一氧化碳的气体气氛,然后进行两相分离,并回收含有铑 - 叔有机磷化合物络合物的有机溶剂相。 作为上述铑化合物的水溶液,通过在回收促进剂如羧酸,胺等存在下,通过氧化处理,从加氢甲酰化反应步骤中分离出的废催化剂液体将含有铑的水溶液萃取到水相中, 氨或无机酸,从而可以通过加氢甲酰化反应/催化剂的回收/催化剂的再生来代替的铑的回收成为可能,并且从无机盐等制备复合催化剂的繁琐步骤,或 可以省略通过在回收的催化剂的水中燃烧而从金属或氧化物制备可溶性盐的步骤。
