Method for separating nickel (O) complex and phosphorus-containing ligand from nitrile mixture |
| abstract |
It has a phosphorus ligand by extracting with hydrocarbon from the reaction effluent obtained during hydrocyanation of unsaturated mononitrile to dinitrile and separating the hydrocarbon and nitrile-containing solution into two phases. A method for extracting and removing nickel (O) complex, wherein at least one polar additive is supplied to the hydrocyanation effluent (feed solution) and / or the extraction stage. [Selection figure] None |
