SEPARATION OF HYDROGEN FLUORIDE FROM A FLUOROCARBON/HYDROGEN FLUORIDE AZEOTROPIC MIXTURE BY SULFURIC ACID |
| 摘要 |
The invention provides a process for the separation of azeotropic mixtures of fluorocarbons from hydrogen fluoride. The most preferred fluorocarbon for this invention is 1,1,1,3,3-pentafluoropropane, which is also known as HFC-245fa. The separation is conducted by adding sulfuric acid to the mixture while the mixture is in either the liquid or gaseous states.
