    摘要: A method for removing cobalt values from the crude product of a cobalt-catalyzed hydroformylation reaction by the application of an airless cobalt demetalling step upstream of the stripping step of a Cobalt Flash hydroformylation catalyst recovery process for C.sub.4 to C.sub.14 olefins, whereby no oxygen is required to oxidize cobalt carbonyls to their cobaltous form. This airless demetalling step may also be used downstream of the stripping step in the case of C.sub.7 to C.sub.20 olefins to remove carbonyls from a water soluble cobaltous salt and carbon carbonyl stream which is taken as bottoms from the stripper reactor.

    摘要: A method for starting a preformer reactor disposed within a hydroformylation system which comprises an oxo reactor, a stripper reactor and a preformer reactor, wherein the bottoms from the stripper reactor comprise at least a water soluble cobaltous salt and wherein the overhead from the stripper reactor comprises entrained volatile cobalt compounds, wherein at least a portion of the entrained volatile cobalt compounds from the stripper reactor are recycled to the preformer reactor to act an initiator in the conversion of the cobaltous salt to cobalt carbonyl.
