    摘要: Acrylonitrile is dimerised in a homogenious liquid phase comprising a phosphinite or phosphonite catalyst, a proton donating solvent and an aromatic and aliphatic hydrocarbon solvent, the aromatic solvent, unconverted acrylonitrile and proton donating solvent is distilled from the product and a mixture is left which separates into two phases, one comprising the catalyst and the other the dinitrile.
