Hydroformylation of 1-octene using Rh catalysts supported on Pcontaining activated carbon materials

Abstract

Hydroformylation is a relevant industrial homogeneously catalyzed reaction, largely applied in industry for production of aldehydes and other bulk chemical platforms. The most common catalysts used at industrial scale are homogeneous cobalt and rhodium complexes, especially those with phosphorus ligands, which further require severe separation processes. Therefore, the heterogenization of these catalysts leads to a cost-efficient and environmentally friendly process, even more convenient when biomass residues are used as renewable carbon-based catalyst supports. The objective of the present work is to use P-containing activated carbon materials prepared from lignin, a co-product from the paper-making industry, as the catalysts support for Rh catalysts for the hydroformylation of 1-octene. The influence of different P/Rh molar ratios, as well as the presence of Mg on the carbon precursor and the catalyst recyclability was studied.
