Abstract
The invention relates to an application of a stabilizer in cobalt-catalyzed hydroformylation reaction, which is characterized in that a compound containing an o-phenylenediamine structure is used as the stabilizer of a cobalt catalyst, and the stabilizer is matched with the cobalt catalyst for use to catalyze olefin and synthesis gas to generate hydroformylation reaction so as to realize recycling of the cobalt catalyst. The stability of a reaction system can be greatly improved, the cost of the catalyst can be reduced, meanwhile, the cobalt catalyst can be prevented from generating precipitates after the reaction, and the catalyst is always kept in a homogeneous phase in the reaction system, is convenient to directly distill and separate and can be directly recycled.
