Removal of the impurity HF acid from hydrofluoroolefins (HFO)
Thread Content
Dear sea friends: Someone has synthesized a hydrofluoroolefin (HFO) that is in liquid form at normal temperature and pressure. Since hydrofluoric acid (HF) is used as a catalyst in the synthesis, the product obtained after synthesis is acidic. It needs to be made neutral later in order to be used. What simple method can be used to remove hydrogen fluoride (HF) from it so that the solution becomes neutral? If you know, please let me know. Thank you!
The simplest method is alkaline cleaning.
Are there any other methods besides alkali washing? Can solid adsorbents be used?
The simplest method is to use quicklime for adsorption.
