Catalyst for preparation of 4-cyanothiazole |
| 摘要 |
4-Cyanothiazole is prepared by the catalytic vapor phase ammoxidation of 4-methylthiazole using a novel catalyst composition comprising a cobalt molybdate catalyst wetted with different levels of potassium hydroxide. The process affords high selectivity to the desired 4-cyanothiazole.
