  • Patent number: 6312578
    Abstract: The invention concerns a method for extracting by electrodialysis a compound comprising at least amine functions capable of protonation from a liquid medium. More particularly it concerns a method for extracting, and separating at least the monomers comprising amine functions capable of protonation from a liquid medium derived from the hydrolysis of polyamides. The method of extraction from a liquid medium consists in subjecting to protonation the amine function(s) of the compounds to be extracted by adjusting the pH of the medium and in separating the compounds by passing them through a cationic membrane under the effect of an electric current. The invention is particularly applicable in processes for the chemical stabilisation of polyamides such as the PA 66 PA 6.

  • Patent number: 4908108
    Abstract: Cerous 3.sup.30 values are converted into ceric 4.sup.+ values, in a conventional separator-free electrolytic cell, by emulsifying an organic phase containing a cerium 4.sup.+ extractant in an aqueous sulfuric phase which includes the cerium 3.sup.+ values to be converted; simultaneously electrolytically oxidizing the cerium 3.sup.+ values into cerium 4.sup.+ values in a zone of electrolysis including an anode and a cathode, whereby the cerium 4.sup.+ values formed are liquid/liquid extracted into the organic phase; separating the resulting emulsion into an aqueous phase and an organic phase enriched in cerium 4.sup.+ values; and recovering the enriched organic phase.
