PROCESS FOR THE MANUFACTURE OF 1,1,1,3,3-PENTAFLUOROPROPANE AND 1,1,1,3,3,3-HEXAFLUOROPROPANE |
| 摘要 |
<p>An integrated manufacturing process for producing HFC-245fa, HFC-236fa or a mixture thereof by reaction of HCC-240fa, HCC-230 or a mixture thereof with HF. HCC-240fa, HCC-230 or a mixture thereof is reacted with hydrogen fluoride in a liquid phase in the presence of a fluorination catalyst. Optionally, produced HCl is removed by distillation. HF present is thereafter recovered by liquid-vapor extraction. Unsaturated compounds are then removed by photochlorination and HFC-245fa, HFC-236fa or a mixture thereof is obtained by distillation.</p> |
