Process for the separation of triphenylphosphine rhodium halide catalysts

摘要

The present invention provides a process for the separation of a triphenylphosphine rhodium halide catalyst from a polar, organic solution which contains other substances hydrogenated by means of homogeneous catalysts and hydrogen, comprising adding to the solution a solid adsorption agent and a reducing agent with a redox potential of less than about -0.1 volt, allowing the mixture to react and, after completion of the reaction, separating the adsorption agent with the adsorbed rhodium from the solution.
