Claims14
A method for preparing acrylonitrile dimer comprising:
- (1) reacting acrylonitrile in the presence of a reaction solvent, a proton-donating solvent, and a phosphorus-based catalyst to prepare an acrylonitrile dimer;
- and
- (2) adding an amine-based solvent to a reaction mixture containing the acrylonitrile dimer prepared in (1) and extracting the same to separate the acrylonitrile dimer and the phosphorus-based catalyst.
