Process for making nitriles |
| abstract |
Adiponitrile is made by reacting 3-pentenenitrile with hydrogen cyanide. The 3- pentenenitrile is made by reacting 1,3-butadiene with hydrogen cyanide and by isomerizing 2-methyl-3-butenenitrile. Both reactions take place in the presence of a catalyst comprising zero valent nickel and a phosphorus-containing ligand. The ligand is partially degraded by hydrolysis or oxidation. Phosphorus-containing ligand degradation products are removed during the production of 3-pentenenitrile and adiponitrile. |
