Supported hydroformylation catalyst and preparation method thereof, and method for synthesizing 4-acetyloxy-2-methyl-2-butenal

Abstract

A supported hydroformylation catalyst and an application method thereof, and a method for synthesizing a 4-acetyloxy-2-methyl-2-butenal are provided. A structure expression of the supported hydroformylation catalyst is Rh@P—N/AC, Rh of which represents an active center of the catalyst and P—N/AC of which represents carriers of the catalyst including an AC carrier and a P—N carrier. The AC carrier in the P—N/AC is an activated carbon and the P—N carrier in the P—N/AC is a phosphine-nitrogen (P—N) organic ligand with one structural formula selected from the group consisting of structural formulas I-IV. The catalyst is capable of achieving catalytic cycling of precious metal and phosphine ligand and has high activity and C2 selectivity.
