Abstract:
1. A method for removing a catalyst from a reactor effluent formed by reacting a substance that is a cyclical hydrocarbon or a cyclical oxygenated hydrocarbon with an oxidant in the presence of the catalyst in an oxidation reactor, the method comprising the following steps: cooling the reactor effluent; separating the reactor effluent into polar and less-polar phases; and transferring the less-polar phase to an ion exchange unit to remove the catalyst, wherein the transferring step is performed prior to recovery of the bulk of any oxidized substance from the reactor effluent, wherein the oxidized substance from the reactor effluent is found in the less-polar phase, and wherein the substance is selected from the group consisting of cyclohexane, cyclohexanone, cyclohexanol, cyclohexylhydroperoxide, and mixtures thereof.
