PROCESS FOR THE PREPARATION OF CARBOXYLIC ACID |
| 摘要 |
<p>A carboxylic acid is prepared by contacting an aqueous solution of the alkali metal or ammonium carboxylate with a liquid cation-exchange agent dissolved in an organic solvent in which the acid is water-immis-cible. As an example, an aqueous solution of trisodium N-(2-hydroxyethyl)ethylenediaminetriacetate is contacted with di(2-ethylhexyl)phosphoric acid in kerosene to thereby form N-(2-hydroxyethyl)ethylenediaminetriacetic acid in the aqueous solution.</p> |
