Recovery of highly fluorinated carboxylic acids from the gas phase |
| 摘要 |
The process for the recovery of highly fluorinated carboxylic acids from off-gas streams, in which the off-gas is brought into contact with an alkaline washing solution of density >1.15 g/cm3 so that the salt of the highly fluorinated carboxylic acid settles out as a separate phase, proceeds particularly advantageously when the alkaline washing solution is a potassium carbonate solution. |
