Process for the separation of catalyst from products obtained in the hydrocarboxylation of unsaturated nitriles

摘要

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.
