ABSTRACT:
Acrylonitrile is catalytically dimerized in the presence of an organic phosphorus (III) catalyst, an inert hydrocarbon reaction solvent and a non-interfering proton-donating solvent; and the dimerized product separated from the catalyst by extraction. In the extraction the dimerized product is preferably dissolved in an extraction solvent and removed from the catalyst phase preparation. In the instant invention, the extraction solvent is an amide, preferably formamide. The extraction solvent and proton-donating solvent may be identical.
