Title:
METHOD FOR PREPARING BUTYRALDEHYDE BY MEANS OF PROPYLENE HYDROFORMYLATION
Document Type and Number:
WIPO Patent Application WO/2016/155338
Kind Code:
A1
Abstract:
A method for preparing butyraldehyde by means of propylene hydroformylation. A heterogeneous catalyst used in the method uses one, two or three of metal Rh, Co or Ir as active components and uses a phosphine-containing organic mixed polymer of a hierarchical porous structure as a carrier, and the phosphine-containing organic mixed polymer is formed by means of copolymerization of an alkylene-containing polydentate organic phosphine ligand and a monodentate organic phosphine ligand. The coordinate bond heterogeneous catalyst is applicable to reactors such as a fixed bed, slurry bed, bubbling bed or trickle bed reactor. The heterogeneous catalyst has good performance in preparing butyraldehyde by means of propylene hydroformylation; butyraldehyde with a high normal/isomeric ratio can be produced; the normal/isomeric ratio can be higher than 25, and the content of propane in the obtained product is lower than 0.1%; the heterogeneous catalyst has good stability, and the separation of the catalyst from a reactant and the product is simple and efficient.
