VERFAHREN ZUR HERSTELLUNG VON FLUORKOHLENWASSERSTOFFEN |
摘要 |
Disclosed is an improved HFC manufacturing processes of the type which produces an intermediate product stream that includes a mixture of HF and at least one compound, usually an HCFC, which is relatively resistant to further fluorination. The improvement involves separating the unreactive compound(s) from the product stream, preferably using liquid:liquid phase separation, and substantially avoiding recycle of the unreactive compound to the fluorination reaction. The separated unreactive compound(s) are substantially free of HF. |
