Abstract

The invention discloses a catalyst for a hydroformylation reaction of alkene and a preparation method and application of the catalyst. The catalyst is prepared from a rhodium complex and a bidentate phosphine ligand, wherein the mole ratio of the bidentate phosphine ligand to metal rhodium in the rhodium complex is (1 to 100): 1; the rhodium complex is at least one of Rh(acac)(CO)2, RhCl3, [Rh(cod)Cl]2, [Rh(CO)2Cl]2, Rh(acac)(C2H4) or [Rh(C2H4)2Cl]2. According to the catalyst for the hydroformylation reaction of the alkene, the problem of the existing catalysts that the dialdehyde selectivityis low during the hydroformylation reaction of cyclic dienes can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of catalysts, and in particular relates to a catalyst for olefin hydroformylation and its preparation method and application. Background technique [0002] The hydroformylation reaction refers to the reaction of olefins with synthesis gas (H 2 +CO) under the action of a catalyst to generate a branched-chain aldehyde and a straight-chain aldehyde with one more carbon. Since Professor Otto Roelen discovered the reaction in 1938, hydroformylation has become one of the most important chemical reactions in today's industrial applications. [0003] The synthesis of phosphorus-containing ligands in the hydroformylation reaction has always been a research hotspot. In the industrial production of olefins, Rh and Co catalysts modified by ligands have shown more excellent results. Therefore, the modification of ligands is a hot field in the research of olefin hydroformylation. [0004] Phosphorus-containing ligands ...
