    摘要： The present invention relates to a method of producing an acrylonitrile dimer, the method including: feeding an acrylonitrile monomer, a nonpolar solvent, an alcohol solvent, and a phosphorus-based catalyst to a dimerization reactor to perform a dimerization reaction and reaction product to a distillation column; feeding the acrylonitrile monomer, the nonpolar solvent, and the alcohol solvent from the distillation column to the dimerization reactor; feeding an acrylonitrile dimer and the phosphorus-based catalyst from the distillation column to an extraction device; oxidizing the phosphorus-based catalyst by feeding water including an acid component to the extraction device to inactivate the phosphorus-based catalyst; and separating the inactivated phosphorus-based catalyst and the acrylonitrile dimer.
