Title:
HYDROFORMYLATION METHOD AND CATALYST USING RHODIUM-RUTHENIUM BIMETAL AND QUADRIDENTATE PHOSPHINE LIGAND
Document Type and Number:
WIPO Patent Application WO/2018/130011
Kind Code:
A1
Abstract:
A homogeneous catalytic reaction method for isomerization and hydroformylation of long-chain internal olefins, and a catalyst. A rhodium-ruthenium metal complex is used as the catalyst. A ligand uses a quadridentate phosphine ligand. By means of the catalytic system, homogeneous internal olefin isomerization and hydroformylation can be performed under a certain temperature and pressure to obtain aldehyde products having high normal/isomeric ratios. The present invention is applicable to not only long-chain internal olefins (≥C8) but also internal olefins having a carbon number less than 8.
