| Abstract: | The extraction of some monocarboxylic acids (methanoic, ethanoic, propanoic, butanoic, chloroethanoic, dichloroethanoic and trichloroethanoic acid) with primary amine N1923 in different diluents were studied. The effects cf diluent, temperature and inorganic salt on the extraction equilibrium were investigated. The extraction mechanism was also examined by means of IR spec-troscopy. The orders of the extraction of the acids are: (1) trichloroethanoic> dichloroethanoic > chloroethanoic > ethanoic acid, the inductive effect is the main factor that influences the extraction equilibrium. (2) butanoic > propanoic > ethanoic > methanoic acid, the cavity effect plays an important role in the extraction process. |
