RECOVERY METHOD FOR PHODIUM COMPLEX CATALYST |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method for efficiently recovering a complex catalyst from an internal part when liquid is drawn out of a reaction apparatus of hydroformyl reaction of an olefin for the purpose of periodic inspection. <P>SOLUTION: In the recovery method for the complex catalyst from the reaction apparatus for performing the hydroformyl reaction of the olefin in the presence of a rhodium-trivalent organophosphoric complex dissolved in a reaction solvent, the reaction apparatus is internally washed with the reaction solvent or washing liquid comprising the component thereof and the remaining complex catalyst is dissolved in the washing liquid. <P>COPYRIGHT: (C)2004,JPO |
