PROCESSO PARA A RECUPERACAO DE UM COMPLEXO DE RODIO |
摘要 |
A method for the recovery of rhodium-triarylphosphine complexes used in the hydroformylation of olefins is described, which comprises contacting an extracted catalyst liquid containing therein a rhodium-triarylphosphine complex with hydrogen in the presence of an alcohol containing 1 to 8 carbon atoms and water to precipitate a hydrogen-coordinated rhodium-triarylphosphine complex, and recovering the precipitated hydrogen atom-coordinated rhodium-triarylphosphine complex from the liquid. |
