CATALYSTS FOR THE FLUORINATION IN THE GASEOUS PHASE OF CHLORINATED ALIPHATIC DERIVATIVES BASED ON CHROMIUM OXIDE MICROSPHERES, AND FLUORINATION PROCESSES USING THESE CATALYSTS |
| 摘要 |
<p>This invention relates to catalysts for gaseous phase fluorination of aliphatic chlorinated derivatives by hydrofluoric acid. The catalysts comprise chromium oxide microspheres obtained by a sol-gel process. This invention also relates to gaseous phase fluorination processes for aliphatic chlorinated derivatives utilizing these catalysts.</p> |
