Removal of organic cations from polar fluids |
| abstract |
ABSTRACT Cationic organic impurities such as ternary sulfonium ions and quaternary ammonium and phosphonium compounds are effectively removed from polar liquids such as water or water/alcohol mixtures by contacting the polar liquid with an absorbent comprising a trini-troarenol such as a picric acid. This method is par-ticularly effective for removing such cationic impuri-ties from polar liquids containing organic zwitterions. 37,417-F |
