Preparation of aromatic isocyanates |
| abstract |
In the process for preparing an organic isocyanate by reacting an organic nitro compound with carbon monoxide in the presence of a catalyst, improved recovery of the organic isocyanate is obtained when the reaction is carried out in the presence of discrete particles of an oxide of iron. Further improvement in the recovery is also obtained when an oxide of molybdenum, an oxide of chromium, or mixture thereof is also added to the reaction mixture along with the oxide of iron. |
