PROCESS FOR THE SEPARATION OF CATALYST FROM PRODUCTS OBTAINED IN THE HYDROCARBOXYLATION OF UNSATURATED NITRILES

摘要

(5239) A process is provided which includes the separation of a hydrocarboxylation-type catalyst together with the hydrocarboxylation solvent from a reaction mixture containing an oxygenated cyanocompound product, the hydrocarboxylation catalyst and the hydrocarboxylation solvent by contacting the reaction mixture with a hydrocarbon to form a hydrocarbon/ solvent conjugate phase, and separating the resulting hydrocarbon phase from the solvent phase.
