| titleOfInvention | Method of preparing organic isocyanates in the presence of molecular sieves |
| abstract | An improved process is disclosed for the phosgenation of aliphatic and aromatic amines to obtain the corresponding organic isocyanates. The improvement comprises carrying out the known phosgenation procedure in the presence of crystalline zeolitic molecular sieves. The organic isocyanate products of the improved process show lighter coloration and improved color stability in comparison to isocyanates obtained by the prior known phosgenation processes. |
