Catalyst for preparation of 4-cyanothiazole |
| 摘要 |
4-Cyanothiazole is prepared by the catalytic vapor phase ammoxidation of DELTA 3-4-methylthiazoline or 4-methylthiazole, using as catalyst a novel composition comprising a slurried chromium cobalt molybdate. The process affords high selectivity in the production of 4-cyanothiazole.
